REVERSE SERVO PISTON
ASSEMBLY—INSPECTION
Inspect lever contacting surface on plug (L)
for excessive wear. Remove and inspect reverse
servo piston seal ring (Z) (neoprene) for dete-
rioration and hardness. Inspect seal ring groove
for nicks or burrs. Inspect servo piston return
spring (0), retainer (N), and snap ring (Q)
for being distorted.
92.
KICKDOWN PISTON ASSEMBLY-
INSPECTION
Inspect riveting of kickdown piston rod (T).
Also inspect guide (R) contacting surface for
nicks or burrs. Inspect seal ring (CC) on guide
for wear and make sure it turns freely in the
groove. Check fit of guide (R) on piston rod.
Inspect the three rings (GG, EE, DD) (two
interlocking) on piston for wear or broken
locks.
Make sure they turn freely in the groove.
It is not necessary to remove rings unless con-
dition warrants. When replacing new rings,
use extreme care so as not to damage the inter-
locking portion of the ring. Inspect kickdown
piston (U) for light scores and wear. Inspect
kickdown piston spring (S) and rod guide snap
ring (M) for being distorted.
93.
ACCUMULATOR PISTON AND
SPRING—INSPECTION
Inspect the two seal rings (X and Y) (one
interlocking) for wear or broken locks and
make sure they turn freely in the grooves. It
is not necessary to remove rings unless con-
dition warrants. When replacing new inter-
locking seal rings, use extreme care so as not to
damage interlocking portion of ring. Inspect
accumulator piston (V) for nicks, burrs, and
excessive wear. Inspect the accumulator spring
(W) for being distorted.
94.
DRIVE SLEEVE
Inspect the front seal ring (neoprene) for
nicks,
deterioration and hardness. Inspect the
interlocking seal ring for wear or broken locks,
and make sure it turns freely in the groove.
It is not necessary to remove rings unless con-
dition warrants. Inspect driving lugs for ex-
cessive wear and bearing surface on outer di-
ameter for nicks, burrs, or scratches.

FRONT OIL PUMP
Inspect front oil pump housing outer seal (on
circumference of housing) and oil seal for de-
terioration and hardness. Do not remove oil
seal from housing unless inspection reveals that
it is necessary. To remove oil seal, use a brass
drift and drive seal out of housing. To replace
front oil pump housing oil seal, position seal
in housing with seal lip toward rotor bore,
(metal portion of seal down) and use driver,
Tool C-3278 to drive seal until tool bottoms on
face of housing, as shown in Figure 91. Inspect
drive sleeve seal ring contacting surface in
housing for wear and scratches. Inspect steel
back bronze type bushing in hub for scratches
or scoring and excessive wear. (Bushing and
housing are serviced as an assembly.) Remove
oil pump rotors and inspect rotor contacting
surfaces for high spots, scratches, burrs, or
grooving.
Inspect regulator body contacting surface on
pump housing face for nicks or burrs. Inspect
housing passages and make definitely sure they
are free from dirt and foreign matter. Clean
and install oil pump gears in housing. Replace
gears,
as identified when removed, with coun-
terbore in pinion gear facing down. Using
straightedge, Tool C-3335 and feeler gauge,
check clearance between pump housing face and
face of rotors, as shown in Figure 92. Clearance
