Drive Chains
Drive chains are located in the chaincase on each side of the machine. Refer to
the Maintenance Interval Chart (page 81) for tension check interval.
Checking Chain Tension
1. Raise the loader following the Loader Raising Procedure (page 52).
2. Rotate each tire by hand. The proper amount of chain defection should be 1/8
in. to 1 in. (3 to 25 mm) forward and rearward tire movement. If the chain
defection is more than 1 in. (25 mm) or less than 1/8 in. (3 mm) in either
direction, the chains should be adjusted.
Adjusting Chain Tension
1. Raise the loader following the Loader Raising Procedure (page 52).
2. Remove the tire from the axle to be adjusted.
3. Loosen (but DO NOT remove) the bolts holding the axle to the chaincase.
4. Front Chain Tension – To tighten the front chain, move the front axle
assembly toward the front of the loader. To loosen the chain, move the front
axle assembly toward the rear of the loader.
Rear Chain Tension – To tighten the rear chain, move the rear axle assembly
rearward. To loosen the chain, move the rear axle assembly toward the front
of the loader.
5. After proper tension is achieved, retighten the bolts.
Important: Be careful not to over-tighten the drive chains. Over-tightening will
cause premature drive chain and axle sprocket wear.
6. Reinstall the tire.
7. Repeat steps 2 through 6 for any other axle requiring adjustment.
8. Lower the loader following the Loader Lowering Procedure (page 53).
Engine Air Cleaner
Important: Failure to follow proper filter servicing instructions could result in
catastrophic engine damage.
The air cleaner assembly consists of an outer (primary) filter element and an
inner (secondary) filter element. An air filter restriction indicator for monitoring
the condition of the elements is located on the front of the air cleaner. If the air
filter becomes restricted, this indicator turns red to warn the operator that the air
cleaner requires service. Push the reset button located at the end of the indicator
after fitting a clean element. For replacement elements, refer to the Replacement
Parts chart (page 52).
Note: Before replacing the filter element(s), push the reset button on the indi-
cator. Start the engine and adjust the throttle to full speed. If the indicator does
not turn red, do not replace the element(s).
