Drive Chains
Drive chains are located in the chaincase on each side of the machine. Refer to
the Maintenance Interval Chart (page 71) for tension check interval.
Check Chain Tension
1. Raise the loader following the "Loader Raising Procedure" (page 46).
2. Rotate each tire by hand. The proper amount of rotation should be
1/8" - 1" (3 - 25 mm) forward and rearward. If the rotation is more than
1" (25 mm) or less than 1/8" (3 mm) in either direction, the chains should
be adjusted.
Adjust Chain Tension
1. Raise the loader following the "Loader Raising Procedure" (page 46).
2. Remove the tire from the axle to be adjusted.
3. Loosen ( remove) the bolts holding the axle to the chaincase.
DO NOT
4. Front Chain Tension - To tighten the front chain, move the front axle
assembly towards the front of the loader. To loosen the chain, move the
front axle assembly toward the rear of the loader.
Back Chain Tension - To tighten the back chain, move the rear axle
assembly rearward. To loosen the chain, move the rear axle assembly
toward the front of the loader.
5. After the proper tension is obtained, retighten the bolts.
Important: Over-tightening the drive chain will cause premature drive
chain and axle sprocket wear.
6. Reinstall the tire.
7. Repeat Steps 2 through 6 for any axle requiring adjustment.
8. Lower the loader following the "Loader Lowering Procedure" (page 46).
