LUBRICATION
Use NLGI Grade 2 grease with a minimum 300°F (149°C) drop point for all lubrication.
Operating Shaft Fittings
Grease every 500 hours of operation. Add one or two pumps of grease from a hand
operated grease gun.
Throwout Collar
Using a hand operated grease gun, add 1 or 2 pumps of grease per 500 hours of operation
(or add grease until grease begins to weep from the ID of the bearing and from between
the release sleeve and the shaft). Rotate the shaft (by hand) while adding grease.
DO NOT OVER GREASE!
Main Bearings
Apply 1 cc. of grease (one shot from a grease gun) every 6 months or 100 hours (whichever
occurs rst) through the tting in the main bearing housing.
Do not over grease. Excess grease can cause the main bearings to overheat.
Pilot Bearings
The pilot bearing supplied with most NACD power take-off units are pre-lubricated and
sealed for life. No maintenance is required. Inspection is recommended every two years
or when the power take-off is removed from the driving component for servicing. If the
pilot bearing supplied with your power take-off is to be periodically lubricated, add one
shot of grease from a grease gun every 100 hours through the tting in the output end of
the clutch shaft. DO NOT OVER GREASE!
