LUBRICATION
• To lubricate the bearings in the
PTO/Clutch USE ONLY NGLI
(National Grease and Lubrication
Institute) APPROVED High grade,
lithium base #2, short fiber grease with
an EP (extreme pressure) additive
recommended for use in high-speed
roller bearings operating at 200°F
(93.3°C). Carlton uses TEXACO
®
STARPLEX II grease. Listed below are
the manufacturer’s suggested guidelines
for lubrication:
1. Release Bearing – using a hand-
operated grease gun, add 1 or 2
pumps of grease per 8 to 10 hours of
operation (or add grease until grease
begins to weep from the ID of the
bearing and from the release sleeve
and the shaft). Rotate the shaft
manually (by hand) while adding
grease. DO NOT OVER
GREASE!
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. PTO cross shaft (engagement
linkage) – grease every 500 hours of
operation. Add 1 or 2 pumps of
grease using a hand operated grease
gun.
