down with a suitable tool, push shifter shaft into
place and turn until ball drops into place in detent
on the shaft detent plate (Fig. 7C-17).
6. Install shift fork.
NOTE: Do not drive the shifter shaft lock pin
into place until the extension has been installed
on the transmission case.
NOTE: The clutch hubs and sliding sleeves are a
selected assembly and should be kept together as
originally assembled, but the three keys and two
springs may be replaced if worn or broken.
1. Push the hub from the sliding sleeve. The keys
will fall free and the springs may be easily removed.
2. Place the two springs in position (one on each
side of the hub), so a tanged end of each spring falls
into the same keyway in the hub. Place the keys in
position and, holding them in place, slide the hub
into the sleeve.

CLEANING AND INSPECTION
TRANSMISSION CASE
Wash the transmission case inside and out with a
cleaning solvent and inspect for cracks. Inspect the
front face which fits against clutch housing for burrs.
If any are present, dress them off with a fine cut
mill file.
FRONT AND REAR BEARINGS
1. Wash the front and rear bearings thoroughly in
a cleaning solvent.
2. Blow out bearings with compressed air.
CA UTION: Do not allow the bearings to spin; turn
them slowly by hand. Spinning bearings will dam­
age the race and balls.
3. Make sure the bearings are clean, then lubri­
cate them with light engine oil and check them for
roughness. Roughness may be determined by slowly
turning the outer race by hand.
BEARING ROLLERS AND SPACERS
All main drive gear and countergear bearing
rollers should be inspected closely and replaced if
they show wear. Inspect countershaft at the same
time and replace if necessary. Replace all worn
spacers.
GEARS AND BUSHING
Inspect all gears and first speed gear bushing and,
if necessary, replace all that are worn or damaged.
