ENGINE CLUTCH ADJUSTMENT
See Figure 7-8 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 Lubrication Guide in Section
9 of this manual.
2. At least once each month, disengage and engage the
clutch several times with engine running. This practice
will clean disc surfaces and prevent discs from seizing.
3. When disengaging clutch, check free travel at lower
bracket. Free travel should be 2-3/8 – 2-1/2 in (60 – 64
mm). Readjust the clutch when free travel decreases to
1-3/8 in (35 mm).
Adjustment
The clutch is adjusted internally through the hand hole on top
of clutch housing. See the manufacturer’s manual for
adjustment instructions.
CAUTION
Avoid Clutch Damage!
Observe the following precautions for the engine clutch:
• Decrease engine speed to idle before engaging or
disengaging clutch.
• Do not run engine longer than twenty minutes with
clutch disengaged.
• Disengage and engage clutch several times monthly
with engine running.
DANGER
Moving Machinery Hazard!
Parts inside clutch rotate when engine is running.
STOP ENGINE before adjusting clutch.
