INSTALLATION (cont'd)
7. Reconnect lube hose attachment (For Hydraulic Linkage Systems).
8. Examine transmission input shaft and clutch release system components for wear and replace if necessary.
(See Figure 5)
9. Install fiber spacer and replace clutch brake (fiber spacer not needed if oversized clutch brake is used).
10. Be sure to properly lube the following components with NLGI grade 2 or 3 Lithium complex grease: Release
Bearing, Yolk Fingers, Cross Shaft Bushings, and Linkage Pivot Points. Note: Applying enough grease to the
release bearing until visible will extend the life of sleeve bushings and input shaft.
Figure 5
Release Yoke
Worn fingers will cause sleeve bushing
wear and adjustment problems.
Cross Shaft Bushing
Worn cross shaft bushings allows side-
ways thrust on release bearing causing
wear on sleeve bushing and premature
wear on release bearing.
Clutch Brake
A clutch brake is used on non-synchronized
transmissions to slow or stop the input shaft
when the clutch pedal is depressed. A clutch
brake is designed to work at engine idle with
the truck stopped. Needs to be replaced at
every clutch installation.
11. Using extreme caution, guide transmission through cover and disc assembly, rotating bell housing shaft so that
release yoke fingers are clear of the pads on the release bearing assembly. (Warning: Transmission must not hang
or be forced into the clutch. This can warp the clutch disc and prevent the clutch from releasing.) NOTE: Do not
add lube to input shaft splines!
12. Install bell housing bolts and tighten progressively to the torque recommended by the vehicle manufacturer.
13. Install clutch linkage. See "Clutch Set-up Procedure".
Transmission Bearing Retainer
Measured input shaft length should be 8.657".
If longer than 8.71" transmission bearing
retainer cap needs to be replaced.
Worn or rough surface will lead to premature
clutch brake wear and adjustment problems.
8.657"
Input Shaft
Roughness in bushing area will lead to
sleeve bushing failure and can cause
bushing to pull out of sleeve.

Transmission Bearing
Wear will allow input shaft
wobble creating vibration
which leads to premature
failure.
Cross Shafts and Linkage
Worn cross shafts and linkage system can
lead to adjustment problems, as well as,
hard pedal and premature sleeve bushing
wear.
Input Shaft Splines
Worn splines on input shaft will cause clutch
to release improperly and may cause splined
hubs in clutch disc to break out.
Input Shaft Pilot
Any wear in area will allow input shaft to
wobble creating vibration which leads to
premature failure.
