Introduction

This Special Instruction provides the procedure to exercise your Hydraulic Excavator. This Special Instruction provides the procedure to store your Hydraulic Excavator. This Special Instruction also provides information for the prevention of rust by using Fluid Film^® for your Hydraulic Excavator.

Do not perform any procedures until you have read the information in this publication.

Fuel Tank Preparation with Additive

Caterpillar recommends the use of Volatile Corrosion Inhibitor (VCI) oil to prevent internal engine damage due to moisture during storage. The inhibitor is an oil stabilizer and rust preventative. The inhibitor can be used with any petrochemical. These inhibitors act by evaporating inside the engine then condensing over the inside surfaces.

The 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 fuel in the machine can deteriorate over time. Adding VCI oil will help the fuel to last longer.

Table 1 lists the various available quantities of VCI oil.

Note: Information pertaining to the use of VCI oil and NOX Additive can be found at the address or phone number of the supplier.

Note: Additional information pertaining to NOX Additive can also be found by entering the following address in your web browser:

Table 2 lists the amount of the NOX Additive for the given machine models.

1. Observe the fuel gauge on the monitor. The level is indicated by individual bars that illuminate.

2. For each bar that is illuminated on the fuel gauge, multiply that number by the amount of additive that is listed for each machine model.

3. Measure the appropriate amount of additive that is necessary to treat the amount of fuel in the machine properly.

4. Pour the additive into the fuel tank.

Upon adding the appropriate amount of NOX Additive, proceed to exercise the machine.

Note: Repeat this application every 90 days. If the machine is stored in sunlight, repeat this application every 45 days. Heat from sunlight will speed the oxidation process in stored fuel. Temperature swings will cause condensation to build, resulting in water accumulation.

Preparation for the Pin Bushing on the Work Tool Linkage and Pin Bushing on the Stick to the Work Tool

When the machine is stored without the work tool attached to the stick, coat the pin bores in the stick and the linkage with grease. Use a wand to coat the machined surfaces and bearing journals with grease.

Note: Never apply grease with your hands. To prevent injury, use a wand or other device. Make sure that the device is long enough to keep hands away from the machinery.

1. Locate 1P-0808 129-1950 129-1919 7X-7664 9X-6488 7X-7665 129-1921 Multipurpose Grease. Fill up a clean container with enough grease order to sufficiently coat all surfaces.

2. By using a wand, begin coating the internal journal of the pin bushings on the work tool end of the stick with grease.

3. Continue to coat the pin bushings in the stick with grease and work outward.

4. Coat the machined bore ring on both sides of the stick with grease.

5. Begin coating the internal journal of the linkage to the pin bushings on the stick.

6. Continue to coat the pin bushings in the linkage with grease and work outward.

7. Coat the machined ring of the bore on both sides of the linkage with grease.

8. Verify that all bushing bores and machined surfaces are fully covered by the grease.

Exercising Standard Worksheet - Lay out and Key Points

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

Machines should be exercised once every 45 days. During periods of high humidity, frequent exercise may be necessary.

Note: Refer to Special Instruction, SEHS9031, "Storage Procedures For Caterpillar Products", "Storage With Exercise". For cold weather starts, refer to the Operation & Maintenance Manual for your machine.

To exercise the machine, perform the following steps.

1. Remove the air inlet and exhaust covers that have been used during the storage period.

2. Perform a walk-around inspection and perform prestart checks as recommended in the Operation & Maintenance Manual for your machine.

   • Ensure that all fluids are at full levels.

3. Ensure that all compartments are at the proper level for operation. Ensure that there is no accumulation of water (standing or colored) in any machine compartment.

4. Ensure that there is ample room to swing the machine. If there is not room to swing the machine, move the machine to an area that allows for full swing. before exercising the swing function.
