Governor/Park Gear Cleaning and Inspection
Thoroughly clean all the governor parts in a suit-
able cleaning solution but do not use any type of
caustic cleaning agents.
The governor weight components (Fig. 20) and the
governor valve (Fig. 21), must slide freely in their
bores when clean and dry. Minor surface scratches
and burrs can be smoothed with crocus cloth
The aluminum governor valve and outer weight
have a hard coating on them. Check condition of this
coating carefully. Do not reuse either part if the coat-
ing is damaged.
Inspect the governor weight spring for distortion.
Replace the spring, if distorted, collapsed, or broken.
Clean the filter in solvent and dry it with low pres-
sure compressed air. Replace the filter, if damaged.
Inspect the park gear for chipped or worn gear teeth
or damaged ring grooves. Replace the gear, if dam-
aged.
Check the teeth on the park gear for wear or dam-
age. Replace the gear if necessary. Inspect the metal
seal rings on the park gear hub. Replace the rings
only if severely worn, or broken.
GOVERNOR/PARK GEAR ASSEMBLY AND
INSTALLATION

sion fluid during assembly.(2) Install new seal rings on park gear hub. Install
ring with interlock ends first and ring with plain
ends last. Slip each ring on hub and seat them in
grooves. Verify that rear ring ends are securely inter-
locked before proceeding.
CAUTION: Exercise care when installing the rings.
They are easily broken if overspread or twisted dur-
ing installation.
(3) Insert filter screen in park gear. Note that gear
has one filter bore that is concentric and one that
has a notch in it. Filter goes in bore that is concen-
tric as shown (Fig. 16).
(4) Position governor body on park gear. Be sure
filter is properly aligned in body recess.
(5) Install governor body bolts. Do not fully tighten
bolts at this time.
(6) Assemble governor weight components (Fig.
20). Then install weight assembly in governor body.
Be sure inner weight snap ring is fully seated
before proceeding.
(7) Install retainer washer and snap ring that se-
cure governor weight assembly in governor body.
(8) Align and install park gear/governor assembly
on output shaft.Be sure hole in output shaft for
governor valve shaft is aligned with governor
valve bore in governor body. Valve shaft will

bind if misalignment occurs. Remove and repo-
sition governor body if necessary.
(9) Verify that shaft bore in governor body and out-
put shaft are aligned.
(10) Verify that governor valve will be indexed
with spotface in output shaft. Reposition valve, shaft
and body if necessary.
(11) Install an E-clip on one end of governor valve
shaft. Be sure rounded side of E-clip is facing out
(away from weight).
(12) Insert governor valve shaft through governor
weight. Be sure shaft slides freely in bore.
(13) Install governor valve on shaft and in gover-
nor body bore.
(14) Install remaining E-clip on governor valve
shaft. Be sure rounded side of E-clip is facing out
(away from valve).
(15) Install governor body-park gear snap rings
and washer on output shaft as follows:
(a) On models with single snap ring, install snap
ring. Be sure ring is seated in shaft.

rings, install thin snap ring first. Then install
thrust washer second, and thick snap ring last
(Fig. 14).
16(c) Verify correct position of snap rings.Be
sure flat side of each snap ring is toward gov-
ernor body.(16) Tighten governor body-to-park gear bolts to 11
Nzm (95 in. lbs.).
(17) Install extension housing/adapter and gasket
on transmission. Tighten housing/adapter bolts to 32
Nzm (24 ft. lbs.).

CAUTION: The pump inner gear is a one way fit.
The bore on one side of the gear inside diameter
(I.D.) is chamfered. Be sure the chamfered side
faces forward (to front of pump).
(6) Install new thrust washer on hub of reaction
shaft support. Lubricate washer with transmission
fluid or petroleum jelly.
(7) If reaction shaft seal rings are being replaced,
install new seal rings on support hub (Fig. 59). Lu-
bricate seal rings with transmission fluid or petro-
leum jelly after installation. Squeeze each ring until
ring ends are securely hooked together.
CAUTION: The reaction shaft support seal rings will
break if overspread, or twisted. If new rings are be-
ing installed, spread them only enough for installa-
tion. Also be very sure the ring ends are securely
hooked together after installation. Otherwise, the
rings will either prevent pump installation, or break
during installation.
(8) Install reaction shaft support on pump housing
(Fig. 60).(9) Align reaction support on pump housing. Use
alignment marks made at disassembly. Or, rotate
support until bolt holes in support and pump housing
are all aligned (holes are offset for one-way fit).
(10) Install all bolts that attach support to pump
housing. Then tighten bolts finger tight.
(11) Tighten support-to-pump bolts to required
torque as follows:
(a) Reverse pump assembly and install it in
transmission case. Position pump so bolts are fac-
ing out and are accessible.
(b) Secure pump assembly in case with 2 or 3
bolts, or with pilot studs.
(c) Tighten support-to-pump bolts to 20 Nzm (15
ft. lbs.).
(d) Remove pump assembly from transmission
case.

REAR CLUTCH INSPECTION
Clean the clutch components with solvent and dry
them with compressed air. Do not use rags or shop
towels to dry any of the clutch parts. Lint from such
materials will adhere to component surfaces and
could restrict or block fluid passages after assembly.
Replace the clutch discs if warped, worn, scored,
burned/charred, the lugs are damaged, or if the fac-
ing is flaking off. Replace the top and bottom pres-
sure plates if scored, warped, or cracked. Be sure the
driving lugs on the pressure and clutch plates arealso in good condition. The lugs must not be bent,
cracked or damaged in any way.
Replace the piston spring and wave spring if either
part is distorted, warped or broken.
Check the lug grooves in the clutch retainer. The
clutch and pressure plates should slide freely in the
slots. Replace the retainer if the grooves are worn or
damaged. Also check action of the check balls in the
retainer and piston. Each check ball must move
freely and not stick.
