on the clutch facing.
Open the cover on the side of the clutch housing
(8" and 10" diameter clutch) and lubricate the clutch
release sleeve collar through the grease fitting every 8
hours. On the 11-1/2" diameter clutch, lubricate the
collar through the fitting on the side of the clutch
housing every 8 hours.
Lubricate the clutch drive shaft pilot bearing through
the fitting in the outer end of the drive shaft (8" and
10" diameter clutch power take-offs) every 50 hours of
operation. One or two strokes with a grease gun should
be sufficient. The clutch drive shaft pilot bearing used
with the 11-1/2" diameter clutch power take-off is
prelubricated and does not require lubrication.
Lubricate the clutch drive shaft roller bearings
through the grease fitting in the clutch housing every
50 hours under normal operating conditions (not
continuous) and more often under severe operating
conditions or continuous operation.
Lubricate the clutch release shaft through the fittings
