the bushing from the reaction shaft. Thoroughly
clean the reaction shaft to remove the chips made by
the remover threads.
(5) Lightly grip the bushing in a vise or with pliers
and back the tool out of the bushing. Be careful not
to damage the threads on the bushing remover.
(6) Slide a new bushing (chamfered end first) on
the installing head Tool SP-3634, and start them in
the bore of the reaction shaft (Fig. 87).
(7) Support the reaction shaft upright on a clean
smooth surface and install handle Tool SP-3549 in the
installing head. Drive the bushing into the shaft until
the tool bottoms.
(8) Thoroughly clean the reaction shaft support as-
sembly before installation.
Assembly
(Fig.
84).
(1) Assemble the pump rotors in the pump housing
(2) Install the reaction shaft support and position
the vent baffle over the vent opening. Install the re-
taining bolts and tighten to 150 inch-pounds torque.
(3) Place a new oil seal in opening of the front oil
pump housing (lip of seal facing inward) using Tool

Remove the tool, retainer and spring.
(3) Invert the clutch retainer assembly and bump
it
on a wood block to remove the piston. Remove the
seal rings from the piston and clutch retainer hub.
Inspect ion
Inspect the facing material on all the driving discs.
Replace discs that are charred, glazed or heavily pit-
ted. Discs should also be replaced if they show evi-
dence of material flaking off or if the facing material
can be scraped off easily. Inspect the driving disc
splines for wear or other damage. Inspect the steel
plate and pressure plate surfaces for burning, scoring
or damaged driving lugs. Replace if necessary.
Inspect the steel plate lug grooves in the clutch re-
tainer for smooth surfaces, plates must travel freely
in grooves. Inspect the band contacting surface on
the clutch retainer for scores,
the contact surface
should be protected from damage during disassembly
and handling.
Note the ball check in the clutch re-
tainer, make sure the ball moves freely. Inspect the
piston seal ring surfaces in the clutch retainer for
nicks or deep scratches, light scratches will not inter-
fere with the sealing of neoprene rings. Inspect the
clutch retainer inner bore surface for wear from the
reaction shaft support seal rings. Inspect the clutch
retainer bushing for wear or scores.
Inspect the inside bore of the piston for score
marks, if light, remove with crocus cloth. Inspect the
seal ring grooves for nicks and burrs. Inspect the
neoprene seal rings for deterioration, wear, and hard-
ness. Inspect the piston spring, retainer and snap
ring for distortion.
Front Clutch Retainer Bushing Replacement
