Belt Maintenance
Checking the Condition and
Tension of the Belts
Service Interval:
Every 50 hours
1.
Stop the engine, set the parking brake, remove the key,
and wait for all moving parts to stop before leaving the
operating position.
2.
Raise the machine and support it with jack stands with
a 460 kg (1,015 lb) capacity.
3.
Check the auxiliary pump-drive belt condition and
tension (
).
Note:
The belt should deflect 1.3 cm (1/2 inch) when
1.4 kg (3 lb) of force is applied to the belt midway
between the auxiliary pump and engine pulleys. If the
belt tension is too high or too low, refer to
the Auxiliary Pump Drive Belt (page 42)
.
4.
Check condition of the transmission-drive belt (
Note:
The transmission belt has a automatic-spring
tensioner.

3.
Adjust the belt tension as follows:
•
Move the auxiliary pump-idler pulley rearward and
outward to tighten the belt.
•
Move the auxiliary pump-idler pulley forward and
inward to loosen the belt.
Note:
The belt should deflect 1.3 cm (1/2 inch) when
1.4 kg (3 lb) of force is applied to the belt midway
between the auxiliary pump and engine pulleys.
4.
Tighten the locknut to 37 to 45 N-m (27 to 33 ft-lb).
Replacing the
Transmission-Drive Belt
Note:
No adjustments are required for belt tension.
1.
Stop the engine, set the parking brake, remove the key,
and wait for all moving parts to stop before leaving the
operating position.
2.
Insert a breaker bar into the socket of the belt-tension
