16000 SERVICE/MAINTENANCE MANUAL POWER TRAIN
ENGINE CLUTCH ADJUSTMENT
See Figure 7-5 for the following procedure.
A disc-type manually operated clutch is mounted between
the engine and the pump drive on this crane. The clutch
allows the pump drive to be disconnected from the engine,
thereby reducing engine load and making start-up easier in
cold weather. The clutch can be engaged or disengaged
while the engine is running or off.
Operation
1. Grease clutch monthly. See Section 9.
2. At least once each month, disengage and engage the
clutch several times with engine running. This practice
will clean the disc surfaces and prevent the discs from
seizing.
3. When disengaging clutch, check free travel. Readjust
clutch when free travel decreases to less than 1-3/8 in
(35 mm).
Adjustment
The clutch is adjusted internally through the cover plate on
top of the clutch housing. See the clutch manufacturerās
manual for adjustment instructions.
CAUTION!
Parts Damage!
Do not run engine longer than 20 minutes with clutch
disengaged. Clutch release bearing can be damaged.
DANGER!
Moving Machinery Hazard!
Parts inside clutch rotate when engine is running. Stop
engine before adjusting clutch.
