Gear Assembly
Note carefully the position of the three
thrust washers to avoid misplacement during
reassembly. Inspect these thrust washers. If they
are worn, scored, or damaged in any manner,
replace them.
Removing the Interlock Assembly
Remove the outer shift levers and shifter shaft
lock pin.
Remove the shifter shafts from the inside of
the case slowly to catch the two interlock ball
bearings as the shafts are being removed. The
interlock sleeve and spring can then be removed.
Now remove the shifter shaft oil seals from the
case. This completes the disassembly of the
transmission.
CLEANING AND INSPECTING PARTS
With the transmission completely disassembled,
all parts should be carefully cleaned so that
they can be thoroughly examined.
Gears
Wash all gears in a cleaning solution. Inspect
for worn or chipped teeth. Slide each gear onto
a new shaft. If it appears to be loose, it must
be replaced.
NOTE: Whenever any transmission gear
requires replacement, the gear with
which it meshes should be replaced also.
Bearings
Bearings must be handled with great care. Wrap
them in a clean cloth or paper until they can
be washed.
To wash a bearing, submerge it in a cleaning
solution that is absolutely free of dirt and
rotate it to flush away all oil and dirt. Dry
the bearing with care.
Carefully examine each bearing for cracked
races, worn, or scored balls.
Main Shaft
Install the gears onto the main shaft to be sure
they slide on and off easily. They should fit
smoothly without excessive play between the
splines. If the fit is tight, look for burred
edges on the splines.
Synchro-Clutch and Friction Rings
Carefully inspect the synchro-clutch and fric-
tion rings. Slide the rings on the cones of the
second speed gear and the clutch shaft. Replace
rings if there is excessive wear on the taper.
Transmission Case
Examine the surfaces of the bearing recesses in
the transmission case for wear or scoring which
indicates that the bearing has been revolving
in its housing. Examine the case for cracks or
other defects.
Be certain that all parts of the case are
thoroughly clean before and during assembly.
REASSEMBLY
When reassembling the transmission, always use
new gaskets and oil seals.
Shifter Shafts and Levers
Install new shift shaft oil seals.
Then reinstall the low and reverse shift shaft,
interlock sleeve, ball bearing and spring. With
the second and high shift shaft installed against
