able. It will be necessary to replace the retainer
if either bushing is scored, or worn.
Inspect the piston and retainer seal surfaces for
nicks or scratches. Minor scratches can be removed
with crocus cloth. However, replace the piston and/or
retainer if the seal surfaces are seriously scored.
FRONT CLUTCH ASSEMBLY
(1) Soak clutch discs in transmission fluid while
assembling other clutch parts.
(2) Install new seals on piston and in hub of re-
tainer. Be sure lip of each seal faces interior of clutch
retainer.
(3) Lubricate lips of piston and retainer seals with
liberal quantity of Door Eze, or petroleum jelly. Then
lubricate retainer hub, bore and piston with trans-
mission fluid.
(4) Install clutch piston in retainer (Fig. 61). Use
twisting motion to seat piston in bottom of retainer.
Do not attempt to push the piston straight in.
This could fold the seals over causing leakage
and clutch slip.
(5) Position spring in clutch piston (Fig. 62).(6) Position spring retainer on top of piston spring
(Fig. 63).Make sure retainer is properly in-
stalled. Small raised tabs should be facing up-
ward. Semicircular lugs on underside of retainer
are for positioning retainer in spring.
(7) Compress piston spring and retainer with Com-
pressor Tool C-3575-A (Fig. 64). Then install new
snap ring to secure spring retainer and spring.
(8) Install clutch plates and discs (Fig. 57). Install steel
plate then disc until all plates and discs are installed.
(9) Install pressure plate and waved snap ring
(Fig. 57).
(10) Check clutch plate clearance (Fig. 64). Clear-
ance should be 1.70 to 3.40 mm (0.067 to 0.134 in.).
If clearance is incorrect, clutch discs, plates pressure
plates and snap ring may have to be changed.

(7) Remove front planetary rear thrust washer
from driving shell.
(8) Separate and remove driving shell, rear plane-
tary and rear annulus from output shaft (Fig. 78).
(9) Remove tabbed thrust washers from rear plan-
etary gear.(10) Remove snap ring that retains sun gear in
driving shell. Then remove sun gear, spacer and
thrust plates.
PLANETARY GEARTRAIN INSPECTION
Clean the planetary components in solvent and dry
them with compressed air.
Check sun gear and driving shell condition (Fig.
79). Replace the gear if damaged or if the bushings
are scored or worn. The bushings are not serviceable.
Replace the driving shell if worn, cracked or dam-
aged.
Replace planetary gear sets if gears, pinion pins, or
carrier are damaged in any way. Replace the annu-
lus gears and supports if either component is worn or
damaged.
Inspect the geartrain spacers, thrust plates, snap
rings, and thrust washers (Fig. 79). Replace any of
these parts that are worn, distorted or damaged. Do
not attempt to reuse these parts.
The planetary gear thrust washers are different
sizes. The large diameter washers go on the front
planetary and the smaller washers go on the rear
planetary. All the washers have four locating tabs on
them. These tabs fit in the holes or slots provided in
each planetary gear.
Inspect the output shaft carefully. Pay particular
attention to the machined bushing/bearing surfaces
on the shaft and the governor valve shaft bore at the
shaft rear.
Replace the output shaft if the machined surfaces
are scored, pitted, or damaged in any way. Also re-
place the shaft if the splines are damaged, or exhib-
its cracks at any location (especially at the governor
valve shaft bore).
The annulus gears can be removed from their sup-
ports if necessary. Just remove the snap rings and
separate the two parts when replacement is neces-
sary. In addition, the annulus gear bushings can be
replaced if severely worn, or scored. However it is
not necessary to replace the bushings if they only ex-
hibit normal wear. Check bushing fit on the output
shaft to be sure.
ASSEMBLING PLANETARY GEARTRAIN
(1) Lubricate output shaft and planetary compo-
nents with transmission fluid. Use petroleum jelly to
lubricate and hold thrust washers and plates in posi-
tion.
(2) Assemble rear annulus gear and support if dis-
assembled. Be sure support snap ring is seated and
that shoulder-side of support faces rearward (Fig.
80).
(3) Install rear thrust washer on rear planetary
gear (Fig. 79). Use enough petroleum jelly to hold
washer in place. Also be sure all four washer tabs
are properly engaged in gear slots.

(4) Install rear annulus over and onto rear plane-
tary gear (Fig. 80).
(5) Install assembled rear planetary and annulus
gear on output shaft (Fig. 81). Verify that assembly
is fully seated on shaft.
(6) Install front thrust washer on rear planetary
gear (Fig. 82). Use enough petroleum jelly to hold
washer on gear. Be sure all four washer tabs are
seated in slots.(7) Install spacer on sun gear (Fig. 83).
(8) Install thrust plate on sun gear (Fig. 84). Note
that driving shell thrust plates are interchangeable.
Use either plate on sun gear and at front/rear of
shell.
(9) Hold sun gear in place and install thrust plate
over sun gear at rear of driving shell (Fig. 85).
(10) Position wood block on bench and support sun
gear on block (Fig. 86). This makes it easier to align
