Special Procedure for Changing
Transmission Input Shaft
In some cases in field repair it may be necessary to replace
only the transmission input shaft due to clutch wear on the
splines.
In these instances the input shaft can be removed without
disassembling the transmission other than removing the
shifting bar housing. Removal of the clutch housing is
optional.
NOTE: The below instructions are for changing the input
shaft only. To change the drive gear, complete
disassembly of the front section must be made.
Disassembly
1. Remove the gear shift lever housing and shift bar
housing from the transmission.
2. Remove the front bearing cover.
3. Engage the mainshaft sliding clutches in two gears and
remove the drive gear bearing nut.
4. Move the drive gear assembly as far forward as possible
and remove the drive gear bearing.
5. Remove the washer from the input shaft.
6. From the front, remove the snap ring from the ID of the
drive gear.

7. Pull the input shaft forward and from the splines of the
drive gear.
Assembly
1. Install the new input shaft into the splines of the drive
gear just far enough to expose the snap ring groove in
the ID of the drive gear.
2. Install the snap ring in the ID of the drive gear.
3. Install the washer on the shaft.

4. Move the forth-fifth speed sliding clutch gear forward to
contact the end of the input shaft in the hub of the drive
gear. Block between the rear of the sliding clutch and the
front of the fourth speed gear. When installing the
bearing this will hold the input shaft in position to seat
the bearing properly.
5. Install the drive gear bearing on the shaft and into the
case bore. Ensure the blocking remains in place.
6. Remove the blocking from the mainshaft and install the
drive gear bearing nut (left-hand thread). Use Loctite
sealant on the threads of the nut and shaft.
7. Peen the nut into the milled slots in the shaft.
8. Install the front bearing cover, shifting bar housing and
gear shift lever housing.
Transmission Installation
1. Refer to Clutch on page 7-31 and install the clutch as
well as perform the required clutch maintenance.
2. Put a very light film of wheel bearing grease on the input
shaft of the transmission.
3. Attach an adequate lifting device to the transmission and
position the transmission so the transmission housing
aligns with the engine flywheel housing.
Ensure the input shaft or clutch release yoke does not
bind on the release bearing.
4. Carefully move the transmission forward, ensuring the
shaft aligns with the splines on the clutch discs and the
