SLIP CLUTCH
During normal operation, the slip clutch can release and slip when encountering an
obstruction or when overloaded. It is designed to slip when the load exceeds 3 times its
nominal rating. When the clutch slips too frequently during normal operating conditions,
it is necessary to replace the clutch linings. NOTE: The PTO shafts are shipped with
the slip clutch disengaged. There are four socket set screws on the inside of the clutch
assembly, which are turned out as far as they go to engage the clutch. Disengage
clutch by turning set screws in fully.
To replace clutch linings, follow this procedure:
1.
Disengage the clutch by turning the four set screws all the way in.
2.
Remove the outside bolts from the clutch assembly and replace the clutch
linings.
3.
When re-tightening the bolts, stop when the clutch spacer starts to touch the
clutch plates. You should be able to just move the spacer by hand when you
have the correct bolt torque.
4.
Engage clutch by turning out set screws after assembly is complete.
