Clutch Greasing Guidelines
To ensure long life and proper operation of the Release
Mechanism of the clutch, it is important to properly lubri-
cate the following areas.
Lubrication
1. Release Bearing: The cast iron bearing housing will
be equipped with either a standard grease fitting or
a lubrication tube extension. If a lubrication tube is
not present, it is necessary to remove the inspec-
tion cover to gain access to the grease fitting. Apply
grease until it purges from the rear of the housing.
Grease on the Transmission Input Shaft will extend
the life of the bronze bushings inside the release
sleeve.
2. Release Bearing Wear Pads: Where the Release
Fork contacts the bearing housing, there are small
hardened steel pads. Apply a small amount of
grease to the wear pads where the Clutch Release
Fork contacts.
3. Low Capacity Inertia Brake (LCIB): The LCIB does
not require lubrication for proper functionality.
4. Cross Shaft Bushings: Lubricate both the left and
the right Cross-Shaft Bushings per OEM recom-
mendations.
5. Clutch Control Linkage: Lubricate the clutch linkage
bell cranks and pivot pins per OEM recommenda-
tions.
6. Pilot Bearing: The pilot bearing inside the flywheel
is a sealed for life bearing and requires no lubrica-
tion. Use a premium pilot bearing to prevent clutch
drag and early bearing failures (C-3, C-4, C-5 Suf-
fix).
Recommended Lubrication
Caution: Incorrect grease and improper lube procedures
will cause bearing failures, bushing wear-out, and yoke tip
and bearing wear pad wear.
Important: Eaton recommends the use of Roadranger EP2
for release bearing lubrication, or an equivalent Lithium
Complex, NLGI #2 or #3 grease with an NLGI LB/GC perfor-
mance rating and a dropping Point temperature of 220 °C
(428 °F) or higher. Failure to use the proper grease may
affect bearing life and void the warranty coverage on your
Eaton product.
Lubrication Interval
For recommended lubrication intervals, see Manual
TCMT0021, Roadranger Lubricant Products, or call
1-800-826-HELP (4357).
