Checking the Condition
and Tension of the Belts

Service Interval:

Every 50 hours

Shut off the engine, engage the parking brake,
wait for all moving parts to stop, and remove
the key.

Check the auxiliary pump drive belt condition
and tension; the belt should be snug. Refer to

Adjusting the Auxiliary Pump Drive Belt (page
42)

Check the condition of the transmission drive
belt.

Adjusting the Auxiliary
Pump Drive Belt

Shut off the engine, engage the parking brake,

) in slots and

torque the flange locknuts to 37 to 45 N∙m (27
to 33 ft lb).

When properly adjusted, the belt should have
1/2 inch (1.3 cm) of deflection with 3 pounds of
force on the belt midway between the auxiliary
pump and engine pulley.

Align the hole and slot in the left hydraulic
compartment cover with the supports of the
machine and secure the cover with the 2
thumbscrews (

Note:

No adjustments are required for belt tension.

Shut off the engine, engage the parking brake,
wait for all moving parts to stop, and remove
the key.

Install the new belt.

Ensure that the idler arm and pulley can move
freely.
