Drive Chains
Drive chains are located in the chaincase on each side of the machine. Refer to
the Maintenance Interval Chart (page 103) for tension check interval.
Checking Chain Tension
1. Raise the loader following the Loader Raising Procedure (page 69).
2. Rotate each tire by hand. The proper amount of chain defection should be 1/8
inch to 1 inch (3 to 25 mm) forward and rearward tire movement. If the chain
defection is more than 1 inch (25 mm) or less than 1/8 inch (3 mm) in either
direction, the chains should be adjusted.
Adjusting Chain Tension
1. Raise the loader following the Loader Raising Procedure (page 69).
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 70).
