Chains
Lubricating the Drive Chains
Lubricate the drive chain every 50 operating hours.
1. Lower the loader arms, stop the engine, and
remove the key.
2. Apply a general purpose oil (10W30) onto
upper and lower chain spans.
3. Start the traction unit and slowly move it
forward to expose unlubed upper and lower
chain spans.
4. Stop the engine and remove the key.
5. Apply oil to newly exposed unlubed chain
spans.
Checking the Drive Chain Tension
Check the drive chain tension before using the
traction unit for the first time and every 50 hours
of use thereafter.
The drive chains should have about 1-1/2 to
2-1/2 inches (3.8 to 6.35 cm) of slack between the
bottom of the chain guard and the bottom chain
span when the top chain span is pulled tight. Use
the following procedure to check the tension:
1. With the bucket installed, lower it into the
ground until the front tires are off of the
ground.
2. Stop the engine and remove the key.
3. Turn the front wheel forward on one side of
the traction unit until the top span of the drive
chain is tight.
4. Measure the distance between the bottom
of the chain guard and the lower chain span
(Figure 30). If the slack in the chain is not
within 1-1/2 to 2-1/2 inches (3.8 to 6.35
cm), adjust the tension (refer to Adjusting the
Tension).

5. Repeat steps 3 and 4 for the other drive chain.
6. Start the engine and raise the bucket to return
the front wheels to the ground.
Adjusting the Drive Chain Tension
1. With the bucket installed, lower it into the
ground until the front tires are off of the
ground.
2. Stop the engine and remove the key.
3. Loosen the nuts securing the axle retaining
bracket (Figure 31).
4. Loosen the nut on the chain tensioning bolt
and loosen the bolt (Figure 31).
