Checking the Torque of the
Wheel Lug Nuts
Service Interval: Yearly
Torque the wheel lug nuts ( Figure 43 ) to 115 to 142
N∙m (85 to 105 ft-lb).
Checking the Condition of
the Chains
Service Interval: Before each use or daily
1. Shut off the engine, engage the parking brake,
wait for all moving parts to stop, and remove
the key.
2. Check the chains on both sides of the machine
for proper tension. The chains should be able to
move up and down 6 to 12 mm (1/4 to 1/2 inch).
3. If chains pop or snap refer to Adjusting the Drive
Wheel Chain Tension (page 39) and Adjusting
the Tine Drive Chain (page 49) .
Checking the Sprocket
Condition
Service Interval: Before each use or daily
1. Shut off the engine, engage the parking brake,
wait for all moving parts to stop, and remove
the key.
2. Inspect sprockets for wear and replace as
required.
Maintaining the Chain
Adjusting the Drive Wheel Chain
Tension
1. Shut off the engine, engage the parking brake,
wait for all moving parts to stop, and remove
the key.
2. Lift the rear of the machine and support using
jack stands or equivalent support.
3. Check the chains on each side of the idler
sprocket, at both sides of the machine, for
proper tension.
The chains should move up and down 6 to 12
mm (1/4 to 1/2 inch).
4. To adjust the chain tension, loosen the idler bolt
and locknut, and push up on the sprocket to
tighten the chain (
Figure 44 ).
Important:
Do not overtighten the chain.
Significant chain wear can occur and will
shorten the life of an overtightened chain.
