FRONT PUMP

1.
Remove the stator support at-

taching screws and remove the stator

support. Mark the top surface of the

pump driven gear with Prussian blue

to assure correct assembly. Do not

scratch the pump gears.

2.
Remove the drive and driven

gears from the pump body.

3.
Refer to Fig. 39 for a disas-

sembled view of the front pump. In-

spect the pump body housing, gear

pockets and crescent for scores.

4.
If the pump housing bushing is

to be replaced, press the bushing from

in Fig. 40.

5.
Press a new bushing into the

pump housing with the handle and

tool shown in Fig. 40.

6. If any parts other than the stator

support or bushings are found defec-

tive,
replace the pump as a unit.

Minor burrs and scores may be re-

moved with crocus cloth. The stator

support is serviced separately.

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

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

fluid screen retaining clip is installed

under the valve body bolt as shown in

Fig. 17.

4.
Install the large control pressure

tube in the valve body and regulator.

5.
Install the small control pressure

compensator tube in the valve body

and regulator.

6. Turn the manual valve one full

turn in each manual lever detent posi-

tion. If the manual valve binds against

the actuating pin in any detent posi-

tion, loosen the valve body attaching

bolts and move the body away from

the center of the case. Move the body

only enough to relieve the binding.

Torque the attaching bolts and check

the manual valve for binding.

7.
Torque the front servo attaching

bolts to specification.
FRONT AND REAR

BAND ADJUSTMENTS

Adjust the front and rear bands as

detailed in Section 2.

VACUUM DIAPHRAGM UNIT

1.
Position the control rod in the

bore of the vacuum diaphragm unit

and install the diaphragm unit. Make

sure the control rod enters the throttle

valve as the vacuum unit is installed.

2.
Torque the diaphragm unit to

specification.

FLUID FILTER

AND OIL PAN

1.
Position the fluid filter on the
rear clip so that the tang enters the

hole in the filter flange. Then, rotate

the filter (clockwise) until the grom-

met is over the pump inlet port of the

valve body regulator and press the fil-

ter down firmly. Install the filter re-

taining clip.

2.
Place a new gasket on the trans-

mission case and install the pan. In-

stall the attaching bolts and lock

washers and torque the bolts to speci-

fication.

If the converter and converter hous-

ing were removed from the transmis-

sion, install these components. Posi-

tion the transmission assembly on the

transmission jack, and refer to Trans-
