GROUP 7-AUTOMATIC TRANSMISSION
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
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 of
the center support, the rollers of the
planetary clutch, and the cam race in
the carrier with vaseline
.
4. 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.
73).
Make sure that all roll-
ers are in the
cage.
S. 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.
73).
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

II. 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 thick ness.
12. Install the output shaft, cardul-
ly meshing the internal gear with the
pinions.
REAR SUPPORT
I. Position the needle bearing and
retainer on the rear support (Fig. 42).
2. Position a new rear support to
case gasket on the rear support. Re-
tain
the gasket
with
transmission
fluid.
3. Install the rear
support.
As the
support is installed, insert the tubes
into the case.
GOVERNOR
I. Position the governor drive ball
in the pocket in the output shaft. Re-
tain the ball with transmission fluid.
2. Install the governor assembly, al-
igning the groove with the ball in the
output shaft.
3. Install the governor with the gov-
ernor body plate toward the front of
the vehicle (Fig. 41). Install the gover-
nor snap

EXTENSION HOUSING
I. Insert the extension housing oil
