Usage:

Caterpillar Products: All

Introduction

Note: Do not perform any procedure outlined in this Special Instruction until you have read and understood this information.

Some products may have exceptions or special circumstances that may impact the instruction found within this special instruction. Do not perform any procedure outlined within this special instruction until you have read and understood the storage information found within your products Operation and Maintenance Manual.

This Special Instruction begins by providing engine storage procedures for any application, then lists detailed steps on how to perform the work for various vehicular systems. Discussions on Generators and Marine Gear are covered separately.

General Requirements

Engine

Caterpillar recommends the use of Volatile Corrosion Inhibitors (VCI) oil to prevent internal engine damage due to moisture during storage. These inhibitors act by evaporating inside the engine, then condensing over the inside surfaces.

This evaporation and condensing process offers full protection to surfaces that cannot be reached with preservatives that require a direct application. This process is also easier to clean from the engine when removing the engine from storage.

The volatile vapors are removed by simply running the engine to operating temperature. A mineral oil base is left behind after the volatile vapors are removed. The oil should then be drained and new oil and filters installed.

Vehicular

Vehicular storage is generalized to recommendations for specific systems such as: hydraulic system, batteries and electrical system, tires and track, implements and attachments, transmissions and drives, air tanks and compressors and cabs.

Corrosive materials can collect on the product during shipment that results in the acceleration of oxidation of the components. Corrosive materials include spray from chemicals for ice melting on roadways, spray from salt or salt air as a result of marine transportation. Corrosive materials must be removed from the product upon the receipt and prior to placing the product into storage. Corrosive materials must be removed from the product prior to applying rust preventative.

Generator

Generator storage provides the necessary information to protect your power generation equipment for periods of time while not in operation.

Marine Gear

Marine gear storage requires the use of VCI oil to protect the marine gear.

Cooling Systems

Cooling systems should be maintained with Caterpillar coolant or equivalent.Caterpillar coolant contains the necessary inhibitors to prevent corrosion and pitting. When used in the proper mixture, the coolant will prevent damage due to rust and freezing.

Storing the engine with water in the cooling system in warm climates is common. In such cases, distilled or deionized water is recommended for use in engine cooling systems. DO NOT use hard tap water or salt softened tap water in engine cooling systems.

If distilled or deionized water is not available, use water that meets the minimum acceptable requirements listed in section "Coolant Specifications" of Supplement, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations For Lubricants, Diesel Fuel, And Coolants".

Note: All Caterpillar engines equipped with Air-to-Air Aftercooling (ATAAC) require a minimum of 30 percent glycol to prevent water pump cavitation.

When approved water (distilled, deionized, or water that meets minimum acceptable Caterpillar requirements) is used, the water MUST be treated with 6 to 8 percent by the volume of water with Caterpillar Supplemental Coolant Additive (SCA). This additive is also calledCaterpillar Cooling System Conditioner, or equivalent. Under NO circumstances should the engine be stored without the addition of the Caterpillar Supplemental Coolant Additive or equivalent.

Note: Refer to section "SCA And Water Cooling Systems", Page 16, of Supplement, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations For Lubricants, Diesel Fuel, And Coolants". Take special note of the chart "Caterpillar SCA Requirements For SCA And Water Cooling Systems" on the same page.

Always fill the radiator full to prevent rusting of the top tank. Do not leave any exposed air space within the radiator. All exposed surface areas will rust.

Caterpillar Coolant and Antifreeze

Caterpillar Extended Life Coolant (ELC) is the preferred coolant to use in cooling systems. Caterpillar ELC provides the best coolant service life, corrosion protection, service life of the water pump seal, and radiator service life. An acceptable alternative to ELC is Caterpillar Antifreeze. Both Caterpillar ELC and Caterpillar Antifreeze contain the necessary corrosion inhibitors to protect the cooling system from rust and pitting of cooling system components. Use Caterpillar ELC or Antifreeze and approved water to provide the necessary coolant mixture required for the lowest ambient temperature anticipated. (For a definition of “approved”water, refer to "TARP Preservative" in this document.)

Note: For additional information, refer to Special Publication, SEBD0518, "Know Your Cooling System".

Note: For additional information specifically about 3600 Engines, refer to Supplement, SEBU7003, "Caterpillar 3600 Series Diesel Engine Fluids Recommendations For Lubricants, Fuels, And Coolants".

Caterpillar ELC and Antifreeze is available from your local Caterpillar dealer. Contact your local Caterpillar Dealer for part numbers and available sizes of containers.

Cooling System Cleaner

Caterpillar Cooling System Cleaner is designed to clean the cooling system of harmful scale and corrosion. The cleaner is available in 1.9L (.5 gal U.S.) containers. Directions for the use of the cleaner are included on the container.

Necessary Equipment

Sprayer

A 331-3626 Fuel Flow Checking Tool Group or an air compressor with a sprayer attachment can be used to prepare the engine for storage.

Change the nozzle adjustment to provide either a spray or a fog pattern. The fog adjustment pattern is better if access to components is difficult. The spray pattern is better for parts on the outside of the engine.

Paint

Outside parts of the engine, marine gear, or other components can best be protected by thorough use of a good quality Caterpillar approved paint. Contact your Caterpillar dealer for ordering a Caterpillar approved paint. Paint provides good protection for a storage period up to 2 years. Before painting, thoroughly clean and dry the product to be free of the following items: dirt, oils, oxides, and corrosion.

Plastic Bags

Use ultraviolet light resistant plastic bags. If a Volatile Corrosion Inhibitor (VCI) oil is used inside the bag and the bag is sealed, the bag must have a minimum thickness of 0.10 mm (0.004 inch)

Sealing Tape

Use a sealing tape with appropriate adhesive properties. DO NOT use duct tape because duct tape will loosen over a short time. Rolls of sealing tape that are 2 inches wide are recommended.

An appropriate quality sealing tape is available from the following suppliers:

Oils and Lubricants

Refer to the Operation & Maintenance Manual for your equipment. Use only the specified oils that are recommended for engine crankcase, drive train, hydraulic system, and other components.

Multipurpose Grease

Use a multipurpose-type grease such as 5P-0960 Grease Cartridge (Molybdenum) and a suitable corrosion inhibitor, to lubricate rod threads, ball joints, linkage, and other components. The 5P-0960 Grease Cartridge (Molybdenum) contains 3 to 5 percent molybdenum disulfide conforming to MIL-M-7866

Note: Grease that contains molybdenum should not be used in u-joints or other high-speed applications with small moving parts.

NLGI No. 2 Grade is suitable for most temperatures.

Filters

Refer to the Parts Book for your equipment. The Parts Book will list all the necessary filter part numbers for engine crankcase, air inlet, hydraulics, marine gear, and other components. These filters are available through your local Caterpillar Dealer.

Coolant Conditioner Test Kit

Use the 8T-5296 Conditioner Test Kit to check the concentration of conditioner in the cooling system. Maintain the cooling system with a 3 to 6 percent concentration of conditioner. Instructions are included with the kit. (Systems consisting of only water should be maintained with a 6 to 8 percent concentration of conditioner. Refer to the section "TARP Preservative" in this Special Instruction.)

Coolant and Battery Tester

The tester is used for checking coolant freezing point and battery fluid condition. Instructions are provided with the tester. The 5P-0957 Coolant and Battery Tester Group is available with the temperature scale in degrees Fahrenheit. The 5P-3514 Coolant and Battery Tester Group is available with the temperature scale in degrees Celsius.

VCI Oil

Volatile Corrosion Inhibitor (VCI) oil can be used in all tanks, engine, fuel tank, hydraulic tank, power steering tank, transmission, differential, and other components. The inhibitor is an oil stabilizer and a rust preventative. The inhibitor can be used in combination with any petrochemical. Apply by using a spraying or fogging pattern.

Special consideration is needed when using VCI oil in compartments where friction material is present in such places as wheel stations and transmissions. The oil in these compartments must be replaced and the compartment will require flushing. Premature failure of fiction material can result if all residual VCI is not removed. Use the following publications or similar procedures to ensure proper flushing of the system.

Note: Aftertreatment Catalyst or Particulate Filters should not be treated with spray on VCI Oil.

Reference: Contamination Control Guidelines, SEBF8438, "Procedure for Filtering Off-Highway Truck Rear Axle Oil"

Reference: Contamination Control Guidelines, SEBF8446, "Procedure for Filtering Off-Highway Truck Hydraulic Oil"

Reference: Contamination Control Guidelines, SEBF8445, "Procedure for Filtering Off-Highway Truck (769-793)"

Caterpillar recommends the use of VCI oil to prevent internal engine damage due to moisture during storage. These inhibitors act by evaporating inside the engine then condensing over the inside surfaces.

Table 4 lists the various available quantities of VCI oil.

Show/hide table

Table 4
Available Quantities of VCI Oil
Part Number	Size
4C-6792	0.946 L (1.0 qt)
4C-6794	18.950 L (5.0 US gal)

This evaporation and condensing process offers full protection to surfaces that cannot be reached with preservatives that require direct application. This process is also easier to clean from the engine when removing the engine from storage.

The volatile vapors are removed by running the engine to operating temperature. A mineral oil base is left behind after the volatile vapors are removed. The oil should then be drained and new oil and filters installed.

VCI oil should not be used full strength on non-ferrous metals where the inhibitor will have direct, prolonged contact. The VCI oil must be diluted as recommended in the instructions that follow.

To be successful when treating an engine with VCI oil, the engine must be sealed when stored. VCI oil is so volatile that any opening left unsealed will allow the vapors to escape, causing the engine to lose protection.

Volatile corrosion inhibitor (VCI), NOX-RUST VCI #10oil, or equivalent, provides liquid and vapor protection to ferrous metal surfaces against corrosion caused by moisture. In a closed compartment, protection is either by direct contact with VCI oil or by contact with VCI vapors. Contact your local supplier for a similar type oil.

Diesel Fuel

Diesel fuel left in fuel tanks and fuel injection systems will sometimes cause problems due to the growth of small organisms. These small organisms may result in plugged fuel filters, corrosion, sticking fuel pumps, or malfunctioning fuel injection valves.

This problem can be minimized by draining the fuel injection pump and refilling the pump with Caterpillar Calibration Fluid.

Note: Calibration Fluid is available from your local Caterpillar Dealer.

Show/hide table

Available Quantities of Caterpillar Calibration Fluid
Part Number	Size
6V-6067	208.1 L (54.9 US gal)
6V-6068	18.9 L (5.0 US gal)

Caterpillar Calibration Fluid is the preferred choice as a preservation fluid because the Caterpillar Calibration Fluid contains Rust and Oxidation inhibitors. If Caterpillar Calibration Fluid is not available, kerosene is a second consideration. However, kerosene does not contain Rust and Oxidation inhibitors and, as the result, Caterpillar Calibration Fluid is by far the best choice. In addition, kerosene is preferred over diesel fuel (another alternative) because kerosene is not as prone to oxidation as diesel fuel. Kerosene also will not thicken as much as diesel fuel during long storage periods.

Fuel tanks should be protected internally with VCI oil and then sealed.

Diesel Fuel Biocide

To prevent the growth of small organisms in the diesel fuel, use diesel fuel biocide such as Biobor JF or equivalent.

Engine

Storage - Greater than 30 Days and less than 1 Year

All Diesel and Natural Gas Engines

Note: If long-term storage for time exceeding 1 year is necessary, contact your local Caterpillar Dealer for the preferred procedure to use in your specific case.

Note: Engines that are stored for more than 6 months must be prelubed and rotated in 6-month intervals.

This storage procedure is to be used for all diesel and natural gas engines in all applications.

If an engine is not used, oil can run off the following parts that normally receive lubrication: cylinder walls, piston rings, main bearings, connecting rod bearings, crankshaft, and gears.

This lack of lubricant allows corrosion to begin to appear on the metal, especially in areas of high humidity (water content in the air).

When the engine is started again, before these surfaces receive oil, the metal-to-metal contact will cause wear. To minimize this wear, use the starter to turn the engine with the throttle in the FUEL OFF position. When oil pressure is shown on the pressure gauge, start the engine.

Clean the engine of any dirt, rust, grease, and oil. Inspect the exterior. Paint areas that contain paint damage with a good quality paint.
Remove any dirt from the air cleaner or cleaners. Check all seals, gaskets, and the filter element for damage.
Apply lubricant to all points shown in the Operation & Maintenance Manual, "Lubrication & Maintenance Table" for your equipment.
Drain and replace the crankcase oil and change the oil filter or filters. For the proper procedure, refer to the Operation & Maintenance Manual for your equipment.
If equipped with an air starter, fill the reservoir with a mixture of 50 percent VCI oil and 50 percent engine oil.
Add VCI oil to the crankcase at the rate of 3 to 4 percent by the volume of the crankcase.
Note: If the engine crankcase is full, drain enough engine oil so the mixture can be added.
Remove the air filter element or elements. Turn the engine at cranking speed with the throttle control in FUEL OFF position. Use a sprayer to add a mixture of 50 percent VCI oil and 50 percent engine oil into the air inlet or turbocharger inlet.
Note: VCI oil mixture is also to be added to the inlet by removing a plug for checking boost pressure/temperature at the cylinder head air inlet area. The sprayer should produce a fog to ensure it is drawn into each cylinder. The minimum application rate is 5.5 mL per L (3 oz per 1000 cu in) of engine displacement.
Use a sprayer to apply a 50 percent VCI oil and 50 percent engine oil mixture into the exhaust openings. The minimum application rate is 5.5 mL per L (3 oz per 1000 cu in) of engine displacement. Seal the exhaust pipe, including any drain holes in the muffler.
Remove the fuel from the secondary fuel filter housing or empty and reinstall the spin-on fuel filter element to remove any dirt and water. Drain the fuel injection pump (sleeve metering only).
Clean the primary fuel filter. Fill with calibration fluid or kerosene. Install the primary fuel filter and operate the priming pump. This procedure will send clean fuel to the secondary filter and engine.
Open the fuel tank drain valve and allow any water or dirt to drain from inside the fuel tank. Apply a spray of 30 mL per 30 L (1 oz per 7.50 gal U.S.) of fuel tank capacity to prevent rust in the fuel tank. Add 0.15 mL per L (.02 oz per 1 gal U.S.) of commercial biocide such as Biobor JF or and equivalent to the fuel.
Apply a small amount of oil to the threads on the fuel tank filler neck and install the cap. Seal all openings to the tank to prevent evaporation of the fuel and preservative.
Remove the fuel nozzles or spark plugs and apply 30 mL (1 oz) of VCI oil mixture (50 percent VCI oil and 50 percent engine oil) in each cylinder.
Use a bar or turning tool to turn the engine over slowly to put the oil on the cylinder walls. Install all fuel nozzles or spark plugs and tighten to the correct torque.
Note: On Natural Gas Engines apply the VCI oil mixture (50 percent VCI oil and 50 percent engine oil) into the holes for the exhaust thermocouples. Adding the mixture must be done while the engine is being turned over. Install the exhaust thermocouples back into the ports.
Note: The VCI oil mixture must be sprayed into the combustion sensor ports on 3600 Engines that cannot be rotated.
Spray the VCI oil mixture (50 percent VCI oil and 50 percent engine oil) on the flywheel, ring gear teeth, and starter pinion. Install the covers to keep in the VCI vapors.
Apply a heavy amount of multipurpose grease (MPGM) to all outside parts that move, such as rod threads, ball joints, linkage, and other components.
Note: Install all covers and ensure that the tape has been installed over all the following openings: air inlet, exhaust openings, flywheel housing, crankcase breather, aftercooler condensate drains, and dipstick tubes.
Ensure that all covers are air tight and weatherproof. Use a waterproof, weather resistant type tape such as Kendall No. 231 or an equivalent. Do not use duct tape. Duct tape will only seal for a short time.
Under most conditions remove the batteries and use the batteries in another application. As an alternative, place the batteries in storage where the batteries can be periodically checked and electrically charged again when needed.
If the batteries are not removed, wash the tops of the batteries until clean. Apply an electrical charge to the batteries to obtain a specific gravity of 1.225.
Disconnect the battery terminals. Place a plastic cover over the batteries.
Note: For additional information, refer to Special Instruction, SEHS7633, "Battery Test Procedure".
Loosen all belts (fan, alternator, and the associated equipment).
Place a waterproof cover over the engine. Ensure that the engine cover is secure, but loose enough to allow air to circulate around the engine to prevent damage from condensation.
Attach a tag to the engine with a notation of the date that the unit was preserved.
Remove the waterproof covers, the dipstick, and the fill caps every 2 months or 3 months and check the engine for moisture or corrosion. If the engine has signs of moisture or corrosion at the check period, repeat the protection procedure.

Aftertreatment System

SCR Systems

Ensure that the SCR system is purged of all Diesel Exhaust Fluid (DEF). The DEF system should be flushed with clean water to eliminate any remaining DEF. DEF will crystallize as the water portion of the DEF evaporates over time. DEF crystals can potentially damage the components in the SCR system. Any spilled DEF should be cleaned up immediately and the area flushed with water.

Catalyst removed from the reactor housing for storage must be stored in an indoor environment out of direct sunlight and moisture. The catalyst face should be covered to prevent impact damage. The temperature range for storage is −30° C (−22° F) to 80° C (176° F). Exposure to high humidity levels may affect catalyst coatings which will affect performance. Catalyst may be stored in VCI paper or plastic but VCI oil should not be sprayed on catalyst.

DOC / DPF Storage

Ensure that all openings are sealed and that water is not able to enter the unit or come in contact with the catalyst/filter. Only VCI paper or plastic should be used, do not spray DOC/DPF substrates with VCI oil.

Fresh Water Systems

This information applies to all systems containing fresh water, such as engine blocks, separate circuit aftercoolers, and other related components.

Note: Water is not the preferred substance to use in cooling systems of Caterpillar diesel engines.

If the stored engine will never be subjected to below freezing temperatures, completely drain the fresh water system. The system can be drained by removing the drain plugs from the engine block, oil cooler, heat exchanger body, and radiator.

Clean the system. Refill the system with approved water and supplemental coolant additive. For a definition of "approved" water, refer to "TARP Preservative" in this document.

If the stored engine will be subjected to below freezing temperatures, completely drain the fresh water system. The system can be drained by removing the drain plugs from the engine block, oil cooler, heat exchanger body, and radiator.

Clean the system. Refill the system with:

Caterpillar Premixed ELC (with distilled water in 50/50concentration),
Caterpillar Antifreeze premix (with distilled water in 50/50 concentration), or
50 percent Caterpillar Antifreeze Concentrate and 50 percent approved water.

Note: Caterpillar Concentrate ELC is available only in the 1 gallon size. The Caterpillar Concentrate ELC should ONLY be used to adjust the level of the cooling system.

Raw Water Systems

Completely drain the raw water system by removing all the drain plugs from the raw water pump, water shield manifolds, heat exchanger bonnets, and aftercooler.

After the system has been drained, inspect all zinc plugs (normally painted red) for corrosion damage.

Note: To ensure complete drainage and evaporation during storage, DO NOT install the drain plugs and zinc plugs. Place all removed plugs in a cloth bag and fasten the bag to the engine for storage.

Removal from Storage

Remove all outside protective covers.
Change the oil and filters. Flush any compartment that contains friction material to removal all residual VCI oil. Premature failure of fiction material can result if all residual VCI is not removed.
Check the condition of the fan and alternator belts. Replace the belts, if necessary. Tighten the belts as specified in the Operation & Maintenance Manual.
Replace the fuel filter elements.
Remove the plastic covers from the air cleaner elements.
Use a bar (or turning tool) to turn the engine in the direction of rotation to ensure that there are no hydraulic locks or resistance.
Before starting the engine, remove the valve cover or covers. Put a large amount of engine oil on the camshaft, cam followers, and valve mechanism to prevent damage to the mechanism.
To ensure immediate lubrication and prevent damage to the engine in the first few seconds after starting, pressure lubricates the engine.
Note: Refer to the topic "Pressure Lubrication Procedure".
Check the condition of all rubber hoses. Replace, as necessary.
Before start-up, test the cooling system for a 3 to 6 percent concentration of coolant conditioner. Add liquid coolant conditioner or a maintenance coolant conditioner element, if equipped.
Test the coolant mixture for proper nitrite level. Adjust the coolant mixture, as necessary.
Prime the engine with clean diesel fuel before starting.
If equipped with a fresh water system, ensure that the system is clean, full, and has the necessary amount of supplemental cooling system conditioner.
If equipped with a raw water system, install all the drain plugs and zinc plugs. Fill the system. The raw water system pumps may need priming before operation.
On the first day of operation, check the entire engine several times for leaks and correct operation.
Note: Refer to the topic "Initial Operation after Storage" within this document.
If the engine was removed from storage in which temperatures of less than -12°C (10°F) were encountered, refer to Service Manual, SEBU5898, "Cold-Weather Recommendations Operation and Maintenance".

Pressure Lubrication Procedure

The engine must have adequate (necessary) lubrication during the first few seconds of operation. A “dry start” (without adequate and necessary lubrication) can cause bearing damage.

To prevent the possibility of a “dry start” and, consequently, bearing damage during the first seconds of operation, pressure lubrication of the engine is necessary. Pressure lubrication consists of filling the main oil passages with oil under pressure.

An optional prelube pump is available for some engines. After the crankcase has been filled with the correct quantity of oil, the prelube pump sends oil to all parts of the engine. This procedure provides lubrication before starting.

The 331-3626 Flow Checking Tool Group can be used as a prelube pump on smaller engines. However, pressure lubrication of larger engines may be difficult because of the limited oil capacity of the tool group. Other sources of clean oil under pressure, such as a service shop central oil supply, can also be used for pressure lubrication.

If the 331-3626 Flow Checking Tool Group is being used, thoroughly clean the tank.
Put the correct amount of engine oil in the crankcase. Put engine oil in the tank of the flow checking tool group.
Note: Use a minimum of 30 percent of the engine oil capacity in the tank of the tool group. Filling the tank several times may be necessary.
Connect the tool to the main oil passage of the engine.
Add air pressure to the tank with the regulator set at 240 ± 35 kPa (35 ± 5 psi). Although the tank has a hand pump, the hand pump will make achieving sufficient air pressure difficult to perform a satisfactory job. Therefore, shop air is the best option, if available.
Note: The shop air system should be equipped with a moisture separator.
Fill the crankcase with the correct amount of oil. The amount of oil used in the pressure lubrication procedure must be subtracted from the refill capacity given in the Operation & Maintenance Manualfor your engine.

Initial Operation after Storage

The quality of oil control components used inCaterpillar Engines ensures that only an operational check at initial start is necessary before operation.

The purpose of this operational check is to ensure that the correct pressures and temperatures are kept in the lubrication, cooling, and fuel systems. Also, the operation ensures that any leaks are corrected.

To ensure a safe, uniform check at initial start, use the following procedure:

Turn the engine at cranking speed with the throttle in FUEL OFF position until engine oil pressure is present.
Operate the engine for 10 minutes at low idle rated speed.
Operate the engine for 15 minutes at half rated load and 3/4 rated speed.
Operate the engine for 30 minutes at full rated load and full rated speed.
Check frequently for leaks such as oil, coolant, and fuel during the first few hours of operation. Repair any leaks as soon as detected.

Machine

Before storage of any machine, perform all required maintenance as recommended in the Operation & Maintenance Manual, "Maintenance Interval Schedule" section of your equipment.

If the equipment is to be stored for a short time period (90 days or less) and the ambient temperature is above -18°C (0°F), use the storage procedure "Storage with Exercise" in this document.

If temperatures are below -18°C (0°F), and for storage (up to 1 year), use the storage procedure "Storage - Up To 1 Year" in this document.

Prepare all electric powered machines for storage using this procedure and store the machine indoors.

Storage - Up To 1 Year

Note: Refer to the section "Storage - Greater than 30 Days and less than 1 Year" in this Special Instruction for additional information.

These instructions provide procedures that will minimize the possibility of damage for storage of 1 year or less.

Note: If long-term storage for a period exceeding 1 year is necessary, contact your local Caterpillar Dealer for the preferred procedure to use in your case.

Perform a complete operational check of the equipment, perform all necessary repairs. Inspect all hydraulic systems before storage, perform all necessary repairs.
- Install and operate all implements.
- Set implements level on ground and check hydraulic oil level. Fill to the full mark, if necessary.
DO NOT disconnect any hydraulic lines.
Clean the equipment to be stored thoroughly to remove all dirt, mud, grease, and oil on all external surfaces.
DO NOT wash new machines when received from the factory.
Prepare all surfaces that are to be painted by removing any accumulation of rust. Apply a Caterpillar approved quality paint to all surfaces that require painting. A good quality paint, applied properly to prepared surfaces, can protect exposed surfaces for up to 2 years.
DO NOT apply paint to the following surfaces:
- All chromed surfaces such as hydraulic cylinder rods.
- Parts not subject to corrosion such as plastic handles, shift guide, handle threads, and name plates.
- Transmission parts such as the following: control line mounting surfaces at lines, transmissions, ratio selector connections, mounting studs, surfaces on output flanges passing through seals, input clutch and drive member, ratio selector linkage and electrical connections
- Control valve stems on seal wiping surfaces.
- Surfaces on shafts passing through seals.
- Machined mounting surfaces.
- Visually inspect the following components to ensure that the components are free of paint: lift, tilt, steering, coupler, cylinder rods, push-pull cables, and center drive shaft slip seal area.
- All other surfaces where paint would be detrimental to machine and/or implement operation and maintenance.
Park the machine in the storage area. Place blocks under the machine and ensure that the machine is level. All buckets, implements, and truck beds that can collect and hold water should be placed and blocked into a position allowing proper draining of water.
Remove the tires and rims on rubber tired machines that will be stored for an extended time. Cover the tires and wheels with black plastic or store inside an enclosed building.
If the decision is made not to remove the rubber tires and wheels, the machine should be supported to relieve the load on the tires.
Reduce tire pressure to the tire manufacturers recommendations and cover with black plastic. The cover is used to provide protection from the sun and elements.
Inspect the tires. Water, entering through cuts and breaks in the rubber and eventually freezing, could cause deterioration to the tires.
Track type machines should be parked and leveled on a surface such as planks or timbers to prevent freezing to the ground.
Note: Machines equipped with sealed track should be exercised every 45 to 60 days to prevent the seizing of the track pins and bushings.
Machines equipped with rubber track should be parked and leveled on a surface such as planks or timbers to keep from freezing to the ground. DO NOT loosen the track tension on rubber tracked machines. Cover the track with black plastic.
Loosen the tension of the conveyor belts on machines that are equipped with conveyors. Refer to the Operation & Maintenance Manual for the procedure for your equipment.

Refer to "ISO 22241" document series for more information about DEF quality control.

Note: Dispose of all fluids according to applicable regulations and mandates.

Exercising

Exercising all moving parts is important for a machine during storage. Exercising renews protective oil films, allows seals to receive the necessary lubricant to minimize seal dry out, and helps prevent seals from taking a set.

Note: DO NOT exercise equipment in temperatures below -18°C (0°F).

Machines should be exercised once every 45 to 60 days. During periods of high humidity, exercising more frequently may be necessary.

To exercise the machine, perform the following:

Remove the inlet and exhaust covers
Perform a walk-around inspection and pre-start checks as recommended in the Operation & Maintenance Manual for your machine.
If any higher than normal leakage is found, DO NOT start the engine until repairs are made.
Ensure that all compartments are at the proper level for operation. Ensure that there is no accumulation of water (condensation) in any machine compartment.
Disconnect the alternator field wire when the unit is operated without the batteries installed. Disconnecting the field wire will prevent damage to the alternator.
Start the machine using the procedure in the Operation & Maintenance Manual.
Ensure that all instruments and controls properly operate.
Allow for a warmup period. Then run the engine at operating temperature for at least 30 minutes to drive off any accumulation of water vapor.
During the 30 minute exercise period, operate all machine controls such as steering, transmission, clutch, brake, and so on. Stop the machine often with seals and bearings in different positions. This procedure will prevent seal damage from being in a SET position.
Operate all power-driven components for at least 1 minute
After completion of the exercise period, install all covers previously removed from all inlet and exhaust openings.

Note: For 3600 Engines DO NOT start the engine if the engine is to remain in storage. Prelube the engine and use the barring device to rotate the crankshaft several revolutions. Repeat this procedure every 6 months. If stored longer than 1 year, reapply the VCl oil.

Generator

Storage

When a generator is in storage, moisture may condense in the winding insulation system. To minimize condensation, always put the generator in a dry storage area.

It is necessary to perform an insulation resistance and Polarization Index (PI) test on all generators at the beginning of storage. Record the results of the insulation test. A PI test should be performed to provide a baseline for future reference.

Note: Ensure that the baseline is established with the unit dry.

To protect against collecting contaminants, the generator should be covered with a plastic cover or a similar type of protective cloth. The protective cover should extend to the ground, but the cover should remain loose around the generator to allow proper ventilation to the generator.

Caterpillar recommends maintaining the temperature of the insulated parts and the air that surrounds the parts at a temperature of at least 5°C or 9°F above ambient temperature to prevent condensation. The following methods are the normal methods for providing the required heat:

Space heaters
Warm air blowers - Do not exceed 207 kPa (30 psi)
Light bulbs - Install a light bulb (60 Watt minimum) inside the generator in the proximity of the stator core at the lowest possible location

Note: The light bulb method only works if there is no air movement around the generator

Ensure that the generator rotor shaft is rotated 10 revolutions every 60 days throughout the storage period.

Removal From Storage

Operate space heaters for at least 24 hours prior to removing covers.

Remove all protective covers. If the unit does not have a space heater, use an alternate means to raise the temperature to at least 5°C or 9°F higher than the ambient temperature. The following methods are the normal methods for providing the required heat:

Space heaters
Warm air blowers - Do not exceed 207 kPa (30 psi)
Light bulbs - Install a light bulb (60 Watt minimum) inside the generator in the proximity of the stator core at the lowest possible location

Note: The light bulb method only works if there is no air movement around the generator

Before start-up of a generator, visually inspect the generator for any foreign material. Use an insulation tester to check insulation resistance for moisture and/or foreign material. Refer to the Operation and Maintenance Manual of the generator for the procedure.

Use the Polarization Index (PI) test procedure to determine the moisture content of the insulation system. PI is greater than or equal to two for a “dry” insulation system. PI is a ratio of the Insulation Resistance Measured for 10 minutes to the insulation resistance value measured after 1 minute. Polarization Ratio equals Insulation Resistance after 10 minutes divided by Insulation Resistance after 1 minute.

Insulation resistance readings with a 50 percent reduction or more from the previous reading, or a PI reading of less than 2 may indicate that the winding has absorbed too much moisture. The generator needs to be dried and retested. If the retest still comes out low the generator will have to be sent to a rewind shop for service. If cleaning or drying is necessary, reference Special Instruction, SEHS9124, "Cleaning and Drying of the Generator".

The system can be stored under long-term conditions without any additional concerns. If the UPS is stored longer than 1 year, you will need to change the oil for the vacuum pump. Thereafter, change the oil in the vacuum pump annually. After completing the oil change for the vacuum pump, you will need to energize the vacuum pump. Operate the vacuum pump for 4 hours. Operation of the pump will ensure proper lubrication of the seals for the vacuum pump.

The vacuum pump is shipped from Service Parts without oil. Therefore, you are not required to change the oil for the vacuum pump for any inventory from service parts.

Do not utilize a vacuum pump that has exceeded specifications for storage of the vacuum pump. Do not utilize a vacuum pump that has exceeded the operational environmental specifications of the vacuum pump. The vacuum pump must be replaced. The replacement cost of the vacuum pump is not a warrantable repair.

Setup Procedure

The vacuum pump has a tamperproof label. This label prohibits the service technician from utilizing a 120 VAC source to begin the vacuum draw on the flywheel during the commissioning procedure. A tamperproof label that is corrupted will void any warranty claim that is associated with the vacuum pump.

To operate the vacuum pump prior to commissioning, disconnect the 240 VAC internal wiring to the receptacle on the right side of the pump. Connect a 240 VAC line cord from an external source. Ensure that you have removed the external 240 VAC source prior to energizing the input terminals.

Refer to the appropriate Operation and Maintenance Manual when you perform the following procedures:

commissioning of the UPS
replacement (field service) of the vacuum pump
installation of bearings for the flywheel

In addition, perform the following operations:

When you change the bearing retainers to install bearings, complete the procedure in a timely manner. Installation of the bearings in place of the bearing retainers should be completed prior to energizing the vacuum pump. Efficient installation will minimize any possible contamination of the chamber for the flywheel. Efficient installation should decrease the time that is required to create an acceptable vacuum level within the chamber for the flywheel.
Do not use a 120 VAC source to begin the vacuum draw on the flywheel.
Remove any externally connected 240 VAC source from the vacuum pump.
Perform a thorough inspection of the vacuum lines and connection points. Look for any possible discrepancies that could result in a vacuum leak.
Verify that the vacuum pump has clean, fresh oil. Verify that the oil for the vacuum pump is filled to the appropriate level. Use 190-8487 Vacuum Pump Oil for the vacuum pump. The pump capacity is 0.7 L. The capacity of the container for the oil (service parts) is 1.0 L.
Do not overfill the reservoir for the vacuum pump. Overfilling the reservoir will cause the following results: misting oil from the vacuum pump, contamination of the interior of the UPS and the appearance of a leaking vacuum pump.
The vacuum pump is equipped with two control switches. One switch controls the gas ballast. The other switch controls the operation mode of the vacuum pump. For normal operation of the vacuum pump, turn the gas ballast switch to the Closed position ("O"). The switch for the mode selector is in the Full Clockwise position.
Remove the air bubbles from the vacuum system by turning the switch for the ballast from the 0 position to the II position. The switch for the ballast is on the top middle of the pump behind the exhaust port. Run the pump for 1 hour. Return the switch for the ballast to the 0 position and allow the pump to pull a vacuum.
For systems that have been in dealer storage with an age equal to or exceeding 12 months, lubricate the O-ring seal of the polymer elbow. The O-ring is on the suction side of the vacuum pump. Utilize 6V-2055 Grease for the O-ring.

NOTICE

Use rubber gloves when handling the o-ring. Do not use bare hands.

Double Conversion Uninterruptible Power Supply

If the uninterruptible power supply must be stored prior to installation, the storage area must be dry. Also, the power supply must be stored in an area that is −25° C (−13° F) to 45° C (113° F).

Note: The batteries should be stored in accordance with the manufacturers instructions.

Energize the UPS on a monthly basis for at least 24 hours when the UPS is stored for extended periods. This action charges the battery. If this action is not performed, the battery may be damaged beyond repair.

The UPS is designed for normal operating conditions of altitude, ambient operating temperature, relative humidity, and ambient transport and storage. The UPS will operate correctly under normal conditions, but the battery may fail. The maximum storage time of the UPS is limited due to the need to recharge the integrated battery.

The following operating conditions may justify special measures of design or protection:

Smoke, dust, or abrasive dust
Humidity, vapor, salt air, bad weather, or dripping
Dust and gas mixture that is explosive
Extreme temperature variations
Improper ventilation
Conductive heat and radiant heat from other sources
Cooling water that contains acid or impurities that could cause scale, silt, electrolysis, or corrosion of the parts that are exposed to the water.
Strong electromagnetic fields
Levels of radiation that are higher than the natural environment
Fungus, insects, and rodents
Operating conditions of the battery

Marine Gear

Storage - Up To One Year

Note: If long-term storage for time exceeding 1 year is necessary, contact your local Caterpillar Dealer for the preferred procedure to use in your case.

Thoroughly clean the marine gear and cover with a quality paint.
If the marine gear will be stored for more than 6 months, add VCI oil at a rate of 2 percent of lube oil capacity. This oil will provide extra protection from moisture.
Operate the marine gear for a short period to circulate oil through the gear.
Cover and place tape over all openings.
Place a waterproof cover over the unit.
Place the marine gear in a clean, dry area during storage.
Put a heavy amount of multipurpose grease (MPGM) on all outside, moving parts (linkage, and so on).

Marine Gear Operation After Storage

Remove all protective covers, grease, and so on.
Ensure that the oil level is correct and there is no concentrations of moisture (water) in the oil.
Replace or clean all oil filters or elements.
