Show/hide table

At operating temperature, the hydraulic tank is hot and under pressure. Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.

Show/hide table

Personal injury or death can result from escaping fluid under pressure. Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury. Always use a board or cardboard when checking for a leak.

General Information

Introduction

The 173-8839 Fluid Storage Filter Cart can be used as a mobile storage container. The fluid storage filter cart can also be used to circulate fluid through dual recycle filters. Fluids, including petroleum-based and water glycol fluids, can be filtered until the desired decontamination level is reached, converting NONFLAMMABLE, contaminated fluids into clean, ready-to-reuse fluids. The unit can also vacuum NONFLAMMABLE fluids directly from:

• a drainage pan

• or from the hydraulic tank of a machine.

Other features include:

• Sized to handle most hydraulic, transmission, crankcase, or cooling system filtering/handling jobs on construction equipment.

• Two 100 mesh, replaceable suction screens to capture larger debris, possibly due to hydraulic system damage.

• Two 10 micron or 22 micron absolute recirculating filters to give the fluid a secondary cleaning.

• Two 5 micron absolute final discharge filters.

• Environmentally friendly.

• CE compliant.

Note: Refer to the Service Information System (SIS) for additional information and oil cleanliness specifications.

Specifications

1. Before using 173-8839 Fluid Storage Filter Cart , determine the type of fluid previously stored in the tank.

2. Drain the contents of the fluid storage filter cart between uses.

3. Clean the inside of the tank to minimize potential damage caused by accumulated contaminants or mixed fluids.

   Note: Although any NONFLAMMABLE fluid can be stored/filtered in the tank, most fluids should not be mixed. These fluids include: antifreeze, hydraulic oil, and soot-contaminated diesel engine oil.

Vacuuming and Storing Fluid

The following valve positions create a vacuum to suction fluid from a drain pan or hydraulic oil tank. When using a drain pan, remove the plug from the ecology valve on the bottom of the hydraulic oil tank. Insert a short length of hose into the valve body to open the valve.

1. Remove the fill cap and screen and insert the wire-reinforced suction hose into the drain pan or the hydraulic oil tank of a machine.

   Note: Store the fill cap and screen of the hydraulic oil tank in a clean area to prevent possible damage and to avoid contamination.

Discharging Fluid

If the fluid meets the specified International Standards Organization (ISO) requirements for application, fluid can be discharged back into the original tank. The following valve positions open the air supply and direct the fluid through the discharge filters and the nozzle controlled discharge hose.

1. Place the discharge hose into the tank being refilled.

Determining Oil Cleanliness

Baseline

1. Establish a "baseline" level of oil cleanliness by taking an initial particle count from the machine.

2. Use the "particle counting" procedure to determine the level of cleanliness.

   Note: The "particle counting" procedure electronically measures the size and quantity of microscopic particles in an oil sample to determine if oil is "clean" or "dirty".

3. Compare the initial particle count readings to readings taken after a failure or whenever a concern exists about possible debris in the hydraulic system.

Particle Counts

There are two types of particle counts: laboratory and field.

Laboratory Particle Count

Cat dealers offer laboratory particle counting as part of the SOS fluids analysis program. Submit an oil sample from a repaired hydraulic system to the Cat dealer. A "baseline" level of oil cleanliness is established and provides a basis for future comparison.

Note: For a more complete explanation of particle counting, refer to Product Bulletin, PEJT5025, "Scheduled Oil Sampling".

Field Particle Count

A field particle count device can be used to determine cleanliness. Refer to the Tool and Shop Products Guide for available field particle count devices.

As part of the field particle count, an oil sample should also be submitted to the Cat dealer SOS laboratory.
