Remove the oil plugs and allow the oil to drain into a suitable container

Check the drained oil for large metal chips or a significant number of metal particles

Clean the plugs and inspect the plugs. Replace a worn plug or a damaged plug

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

Add oil through the opening of the oil fill/drain plug that is now at the top

Fill the final drive to the bottom of the opening for the oil check plug

Install the two oil plugs. Tighten the oil plugs to a torque of 27 ± 1 N·m (20 ± 0.7 lb ft)

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.

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.

Select the location of the radiator cap

Is the sample taken from the radiator and not from the Coolant Overflow Reservoir?

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.

NOTICE: Mixing ELC with other products will reduce the effectiveness of the coolant. This could result in damage to cooling system components.

Note: The machine was shipped from the factory with Extended Life Coolant (ELC) in the cooling system.

Drain the coolant whenever the coolant is dirty or whenever the coolant is foaming.

Allow the machine to cool before you change the coolant.

Slowly loosen the radiator cap in order to relieve system pressure. Remove the radiator cap.

Remove the drain plug or open the drain valve (if equipped) and allow the coolant to drain into a suitable container.

1. Remove the filler plug for the right side drive chain case. The oil level should be at the bottom of the threads on the fill port. If necessary, refer to Operation and Maintenance Manual, “Drive Chain Case Oil - Change” for the proper procedure to add oil.

2. Apply 169-5464 Quick Cure Primer and 5P-3413 Pipe Sealant to the threads on the filler plug. Install the filler plug.

3. Repeat the process for the left side drive chain case.

Drive Chain Tension - Check/Adjust

Note: Steel tracks that go over the tires should only be used with pneumatic tires. When you use steel tracks that go over tires or any drive train device except tires, the interval for checking the drive chains should be reduced to every 100 Service Hours. The use of rubber tracks that go over the tires is not recommended.

Note: There are four drive chains on the skid steer loader that must be checked and adjusted.

1. Park the machine on level ground and stable ground.
