Shift Socket
Inspect the shift socket for wear or damage.
Replace the socket if the roll pin or shift shaft bores
are damaged. Minor nicks in the shift lever ball seat
in the socket can be smoothed down with 400 grit
emery or wet/dry paper. Replace the socket if the ball
seat is worn or cracked. Do not reuse the original
shift socket roll pin. Install a new pin during assem-
bly. The socket roll pin is approximately 33 mm
(1-1/4 in.) long.
Output Shaft And Geartrain
Inspect all gears for worn, cracked, chipped or bro-
ken teeth. Also check condition of the bearing bore in
each gear. The bores should be smooth and free of
surface damage. Discoloration of the gear bores is a
normal occurrence and is not a reason for replace-
ment. Replace gears only when tooth damage has
occurred or if the bores are brinnelled or severely
scored.
Inspect the shaft splines and bearings surfaces.
Minor nicks on the bearing surfaces can be smoothed
with 320/420 grit emery and final polished with cro-
cus cloth. Replace the shaft if the splines are dam-
aged or bearing surfaces are deeply scored, worn or
brinnelled.
ASSEMBLY
NOTE: Sealers are used at all case joints. Use
Mopar Gasket Maker or equivalent for all case joints
and Mopar silicone sealer or equivalent for the
input shaft bearing retainer.
SYNCHRONIZER
(1) Slide sleeve onto the hub, leaving enough room
to install the spring in the hub and strut in the hub
groove.
(2) Install first spring in the hub, then install a
strut over the spring. Verify spring is seated in the
spring bore in the strut.
(3) Slide sleeve onto the hub far enough to hold
the first strut and spring in place.
(4) Place detent ball in the top of the strut, then
press the ball into place with a small screwdriver.
Work the sleeve over the ball to hold it in place.
(5) Repeat procedure for the remaining springs,
struts and balls. Use tape or rubber bands to tempo-
rarily secure each strut and ball as they are
installed.
(6) Verify the synchro three springs, struts and
detent balls are all in place (Fig. 49).
