SPECIAL PROCEDURE FOR CHANGING CLUTCH
(INPUT) SHAFT
In some cases in field repair it may be necessary to
replace only the input shaft due to clutch wear on
the splines.
In these instances the input shaft can be remov-
ed without disassembling the transmission other
than removing the shifting bar housing. Removal
of the clutch housing is optional. Following is the
detailed procedure:
Disassembly
1. Remove gear shift lever housing and shift bar
housing from transmission.
2. Remove the front bearing cover.
3. Remove snap ring from input shaft.
4. Move the drive gear assembly as far forward as
possible and remove the drive gear bearing.
5. Remove the washer from input shaft.
6. From the front, remove the snap ring from ID of
drive gear.
7. Pull the input shaft forward and from splines of
drive gear.
Reassembly
Install bushing in new input shaft.
1. Install new input shaft into splines of drive gear
just far enough to expose snap ring groove in ID of
drive gear.
2. Install snap ring in ID of drive gear.
3. Install washer on shaft.
4. Move the fourth-fifth speed sliding clutch gear
forward to contact end of input shaft in hub of drive
gear. Block between rear of sliding clutch and front
of the fourth speed gear. When installing bearing
this will hold input shaft in position to seat the
bearing properly.
5. Install drive gear bearing on shaft and into case
bore, making sure blocking remains in place.
6. Remove blocking from mainshaft and install the
snap ring on input shaft.
7. Re-install front bearing cover, shifting bar hous-
ing and gear shift lever housing.
NOTE: The above instructions are for changing the
input shaft only. To change the drive gear, com-
plete disassembly of the front section must be
made.
