DISASSEMBLY AND ASSEMBLY (Continued)
(10) Install thrust plate on intermediate shaft hub
(Fig. 173). Use petroleum jelly to hold thrust plate in
place.
(11) Check seal ring on rear clutch retainer hub
and seal rings on input shaft (Fig. 174). Also verify
that shaft seal rings are installed in sequence shown.
(12) Install rear clutch thrust washer (Fig. 175).
Use additional petroleum jelly to hold washer in
place if necessary.
(13) Align clutch discs in front clutch and install
front clutch on rear clutch (Fig. 176). Rotate front
clutch retainer back and forth until completely
seated on rear clutch retainer.
(14) Coat intermediate shaft thrust washer with
petroleum jelly. Then install washer in rear clutch
hub (Fig. 177). Use enough petroleum jelly to hold
washer in place. Be sure grooved side of washer
faces rearward (toward output shaft) as shown.
Also note that washer only fits one way in
clutch hub. Note thickness of this washer. It is a
select fit part and is used to control transmission end
play.

(15) Align drive teeth on rear clutch discs with
small screwdriver (Fig. 178). This makes installation
on front planetary easier.
(16) Raise front end of transmission upward as far
as possible and support case with wood blocks. Front/
rear clutch and oil pump assemblies are easier to
install if transmission is as close to upright position
as possible.
(17) Slide front band into case.
(18) Install front and rear clutch units as assembly
(Fig. 179). Align rear clutch with front annulus gear
and install assembly in driving shell. Be sure out-
put shaft thrust washer and thrust plate are
not displaced during installation.
(19) Carefully work assembled clutches back and
forth to engage and seat rear clutch discs on front
annulus gear. Also be sure front clutch drive lugs are
fully engaged in slots of driving shell after installa-
tion.
(20) Assemble front band strut.
(21) Install front band adjuster, strut and adjust-
ing screw (Fig. 180).
(22) Tighten band adjusting screw until band just
grips clutch retainer. Verify that front/rear clutches
are still seated before continuing.
(23) Check seal rings on reaction shaft support
hub. Verify that seal rings are hooked together and
that front clutch thrust washer is properly positioned
(Fig. 181). Use petroleum jelly to hold thrust washer
in place if necessary.
(24) Lubricate oil pump body seal with petroleum
jelly. Lubricate pump shaft seal lip with petroleum
jelly.
(25) Thread two Pilot Stud Tools C-3288-B into
bolt holes in oil pump bore flange (Fig. 182).
(26) Align and install oil pump gasket (Fig. 182).

(27) Install oil pump (Fig. 183). Align and position
pump on pilot studs. Slide pump down studs and
work it into front clutch hub and case by hand. Then
install 2 or 3 pump bolts to hold pump in place.
(28) Remove pilot stud tools and install remaining
oil pump bolts. Tighten bolts alternately in diagonal
pattern to 20 N·m (15 ft. lbs.).
(29) Measure input shaft end play (Fig. 184).
NOTE: If end play is incorrect, transmission is
incorrectly assembled, or the intermediate shaft
thrust washer is incorrect. The intermediate shaft
thrust washer is selective.
