ASSEMBLY
OF
TRANSMISSION

Do
not use
force
to
assemble
mat-

ing parts.
If the
parts
do not
assemble

freely, examine them
for the
cause_pf

the difficulty. Always
use new
gaskets

and seals during
the
assembly opera-

tions.

CLUTCH ASSEMBLIES

1.
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.

The production center supports
are

chamfered
at the
edge
of the

service center supports

are
not
chamfered.
The
following
as-

sembly procedures cover both types
of

center supports.

and front thrust bearing race
if
used

in
the

of the

planetary clutch,
and the cam

FIG. 54—Planetary Clutch, Planet Carrier and Center Support

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. 55). 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 and onto the inner

race.

7.
Push the planet carrier all the

way forward.

PLANET

CARRIER
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 direction.

9. Install the selective thrust washer

on the pinion carrier rear pilot. II the

end play was not within specifications

when checked prior to disassembly,

replace the washer with one of proper

thickness. Refer to the Specification

Section of Group 7 for selective thrust

washer thickness.

10.
Install the output shaft, careful-

ly meshing the internal gear with the

pinions.

Installation—Center Support

not Chamfered

1.
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 of

the center support, the rollers of the

planetary clutch, and the cam race in

the carrier with vaseline.

i. Install the^ planetary clutch on

the center support with the saw teeth

of the clutch cage pointing in the

clockwise direction as viewed from the

rear (Fig. 56). Make sure that all roll-

ers are in the cage.

5.
Position the planet carrier on the

support so that the cams in the carrier

engage the saw teeth on the clutch

cage.

6. Push the planet carrier forward

until the rollers are felt to contact the

surface of the cam race.

7.
While applying forward pressure

on the carrier, rotate it counterclock-

wise as viewed from the rear. This will

cause the rollers to roll toward the

large opening end of the cams in the

race,
compressing the springs slightly,

so that the rollers will enter the cams.

8. Some rollers may become

cocked preventing their entry into the

outer race. These rollers must be posi-

tioned individually with a small screw-

driver by pushing the rear of the roll-

ers toward the transmission and into

the cam race (Fig. 56). Keep pressure

applied to the carrier at all times.

9. After all of the rollers have been

started into the cam race, rotate the

carrier counterclockwise while pushing

it forward. Again, straighten any roll-

ers which still may be in a cocked po-

sition and prevent the carrier from

sliding onto the support.

10.
Make sure that all springs are

entered in the cam race before at-

tempting to push the carrier on the

support. Push the carrier all the way

forward and check the operation of

the clutch by rotating it in a counte-

rclockwise direction. The carrier

should rotate counterclockwise with a

slight drag and should lock up when

attempting to rotate it in a clockwise

direction.

11.
Install the selective thrust wash-

er on the pinion carrier rear pilot. If

the end play was not within specifica-

tions when checked prior to disassem-

bly, replace the washer with one of

proper thickness. Refer to the Specifi-

cation Section of Group 7 for selective

thrust washer thickness.procarmanuals.com
