3.2.1 Bronze & Greasable Ball Type Release Bearing
Using a hand operated grease gun, add 1 or 2 pumps of grease per 8-10 hrs. of
operation (or add grease until grease begins to weep from the I.D. of the bearing and
from between the release sleeve and the shaft). Rotate the shaft (by hand) while adding
grease. DO NOT OVER GREASE!
3.2.2 Main Bearings
Grease every 100 hours
of operation. Add grease
until grease is forced out of
the labyrinth seal(s) around
the shaft. Manually (not by
starting the engine) rotate the
shaft while adding grease.
3.2.3 Pto Cross Shaft
Grease every 500 hours of
operation. Add one or two
pumps of grease from a hand
operated grease gun.
3.2.4 Clutch Linkage And
Levers
Lubricate sparingly with
engine oil every 500 hours of
operation.
3.2.5 Pilot Bearing (Except Non-Greasable Type)
Using a hand operated grease gun, add 1 or 2 shots of grease per 100 hrs. of
operation.
3.2.6 Pilot Bearing (Non-greasable Type)
Cartridge-type pilot bearings are sealed units and require no additional lubrication.
The lubrication intervals and the amount of grease used should be adjusted to minimize
the amount of grease forced out of the bearing housing and the clutch release bearing.
A small amount of grease driven from the bearing housing and the clutch release
bearing is an indication that enough grease is being provided.
Some PTO shafts
have 2 possible grease
locations; one location
will be plugged and the
other will have a grease
fitting. If the PTO uses a
non-greasable cartridge
type pilot bearing,
both locations will be
plugged or the shaft will
have no drilled passage-
ways at all.
