Caterpillar Compact Track Loader 289C

Refer to the Service Manual for the complete adjustment procedure for the engine valve lash.

A qualified mechanic should adjust the engine valve lash and the fuel injector timing because special tools and training are required.

NOTICE: Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling. Using the same pump for both types of samples may contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers.

Refer to the Operation and Maintenance Manual, “Access Doors and Covers” for the location of the service points.

WARNING: Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.

Coolant sample obtained from the radiator?

Note: Do not take the sample from the Coolant Overflow Reservoir.

Coolant sample obtained as close as possible to the recommended sampling interval?

Refer to Operation and Maintenance Manual, “Cooling System Coolant Sample (Level 1) - Obtain” for the guidelines for proper sampling of the coolant. Submit the sample for Level 2 analysis.

For additional information about coolant analysis, see Special Publication, SEBU6250, “Caterpillar Machine Fluids Recommendations” or consult your Caterpillar dealer.

Position one final drive so that the oil fill/drain plug is at the top.

Use an 8 mm allen wrench. Remove the oil check plug.

Check the oil level. The oil should be near the bottom of the opening for the oil check plug.

Add oil through the opening for the oil fill/drain plug, if necessary.

Install the oil plugs. Tighten the oil plugs to a torque of 27 ± 1 N·m.

Repeat the procedure for the other final drive.

Is one final drive positioned so that the oil fill/drain plug is at the bottom?

Did you use an 8 mm (5/16 inch) allen wrench to remove the oil plugs and allowed the oil to drain into a suitable container?

Did you check the drained oil for metal chips or particles?

If there are any chips or particles, consult your Caterpillar dealer.

Did you clean the plugs and inspect them?

Did you replace a worn plug or a damaged plug?

Is the final drive positioned so that the oil fill/drain plug is at the top?

Did you add oil through the opening of the oil fill/drain plug that is now at the top?

WARNING: Personal injury can result from contact with refrigerant. Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury. Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant. Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.

Personal injury or death can result from inhaling refrigerant through a lit cigarette. Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death. Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.

Use a certified recovery and recycling cart to properly remove the refrigerant from the air conditioning system.

NOTICE: If the refrigerant system has been open to the outside air (without being plugged) for more than 30 minutes, the receiver-dryer must be replaced. Moisture will enter an open refrigerant system and cause corrosion which will lead to component failure.

Refer to Service Manual, SENR5664, “Air Conditioning and Heating R-134a For All Caterpillar Machines” for the proper procedure to change the receiver-dryer assembly and for the procedure to reclaim the refrigerant gas.

Note: The receiver-dryer must also be replaced when the air conditioning system is evacuated.
