ASSEMBLY OF TRANSMISSION
Do not use force to assemble mat-
ing parts. If the parts do not assemble
freely, examine them for the cause of
the
difficulty.
Always use new gaskets
and seals during the assembly opera-
tions.
CLUTCH ASSEMBLIES
I. Install the front band in the
transmission case so that the anchor
end is aligned with the anchor in the
case
.
2. Make sure the thrust washer is
in place on the input shaft. Lift the
clutch assemblies out of the holding
block
.
Do not allow the clutches to
separate.
3. Install the clutch sub-assemblies
in the transmission case while posi-
tioning the servo band on the drum.
Hold the units together while install-
ing them
(Fig.

CENTER SUPPORT,
ONE-WAY CLUTCH,
PINION CARRIER, AND
OUTPUT SHAFT
The production center supports are
chamfered at the edge of the race
(Fig.
71). The service center supports
are not chamfered
.
The following as-
sembly procedures cover both types of
center
supports.
Installation -Center Support
With Chamfered Edge
I. Install the center support and the
rear
band
in the case.
2.
Install the primary sun gear
rear
thrust
bearing
race, needle bearing,
and front thrust bearing race if used
in the planet carrier using
petroleum
jelly to retain them in place.
3. Lubricate the bearing surface on
the center support, the rollers of the
planetary clutch, and the cam race in
the carrier with
petroleum
jelly (Fig
.
71).
4.
Install the planetary clutch in the
carrier (Fig. 72).
5.
Carefully position the planet car-
rier on the center support. Move the
carrier forward until the clutch rollers
are felt to contact the bearing surface
of
the
center
support.

6. While applying forward pressure
on the planet carrier, rotate it counte-
rclockwise,
as viewed from the rear
(Fig.
72). This will cause the clutch
rollers to roll toward the large open-
ing end of the cams in the race, com-
pressing the spring slightly, so that the
rollers will ride up the chamfer on the
planetary support
a
nd onto the inner
race
.
7. Push the planet carrier all the
way forward
.
8. Check the operation of the plan-
etary clutch by rotating the carrier co-
unterclockwise. It should rotate count-
erclockwise (viewed from the rear)
with a slight drag, and it should lock
up when attempting to rotate it in a
clockwise
dir::ction.
9. Install the selective thrust washer
on the pinion carrier rear pilot. If the
end play was not within specifications
