AND REPLACEMENT
During the repair of the sub-
assemblies, certain general instruc-
tions which apply to all units of the

instructions are given here to avoid
unnecessary repetition.
Handle all transmission parts care-
fully to avoid nicking or burring the
bearing or mating surfaces.
Lubricate all internal parts of the
transmission with transmission fluid
before assembly. Do not use any
other lubricants.
Gaskets and thrust washers may

facilitate assembly. Always install
new gaskets when assembling parts
of the transmission.
Tighten all bolts and screws to the
recommended torque. Refer to Part
7-1 for cleaning and inspection pro-
cedures.

2. Remove the drive and driven
gears from the pump body.
3. Refer to Fig. 37 for a disassem-
bled view of the front pump. Inspect
the pump body housing, drive gear
bushing, gear pockets, and crescent
for scores.
4. Inspect the mating surfaces of
the pump body and cover for burrs.
5. Inspect the drive and driven
gear bearing surface for scores, and
check the gear teeth for burrs. In-
spect the stator support splines for
burrs and wear.
6. Check the fluid passages for ob-
structions.
7. If any parts other than the
stator support are found defective,
replace the pump as a unit. Minor
burrs and scores may be removed
with crocus cloth. The stator support
is serviced separately.
