the retainer from the groove in
the ring so that the ring may be
e a s i l y slipped out. See Fig-
ure 4-29.

enough to catch the tips of the
tool jaws. Then open the jaws
of the tool enough to expand the
retainer back into the counter-
bore and allow the ring to slip
in the sleeve. Install both rings
in this manner.
CAUTION: Make s u r e the re-

all the way around the ring, so
that the ring can turn freely. See
Figure 4-30.

ing gear on the clutch sleeve.
e. Synchronizer Energizing
Springs
1. It will be noticed upon examin-
ing these springs that one of the
ends is slightly offset. Each
spring must be assembled in its
groove in the clutch gear and
second speed gear. The offset
or locking end must be between
the third and fourth teeth in either
bank of teeth. See Figure 4-31.
2. Under n o r m a l operation it
should never be necessary to re-
place the energizing springs.
However, should an energizing
s p r i n g be removed for any
reason, a new spring should be
used for replacement.

nut retainers downward and re-
move nuts, nut retainers, and
shifter shaft retainer.

3. Remove cam retaining ring and
cams.
4. Using a soft hammer, remove
the s h i f t e r shaft and fork
assemblies.
5. Remove interlock shaft.
6. Clean all parts and inspect for
damage or excessive wear. Check
the "O" rings at the ends of the
shifter shafts for wear. Replace
any parts required.
