BEARINGS
DO NOT place bearings where dirt is liable to mix
with the lubricant in the bearings.
Bearings should be washed in clean gasoline or
kerosene. DO NOT SPIN the bearings and particu-
larly do not spin bearings with an air hose. Spinning
a bearing at high speeds will almost certainly do
considerable damage. After washing the bearings,
blow them out with clean dry air. Direct the flow of
air into the open face of the bearing while holding the
inner race and slowly rotate the outer race by hand.
DO NOT ALLOW the air to spin the bearing.
(a) In s p e c t the bearing for cracks and defects.
(b) Lubricate the bearing with clean, new engine
oil, rotating the bearings by hand in order to spread
the lubricant over all surfaces.
Transmission mainshaft bear in g s are built origi-
nally with e n d play and although they may feel quite
loose, it does not necessarily indicate that they are
worn and unfit for use.
GEARS
Inspect all gears for damaged teeth. Remove any
and all raised edges from tooth surfaces b y hand
stoning. Pitted and worn gears should be replaced.
CONTROL SHAFT AND SEAL
Recommended clearance between control shaft
and overdrive housing bore is .001" to .003" but
clearance of twice this amount if not accompanied by
oil leakage is permissible.
If a new control shaft seal is installed make sure
that it does not interfere with rotation of control shaft.
OVERDRIVE MAINSHAFT OIL SEAL
If the seal is hard, cracked, or glazed, or if signs of
oil leakage are apparent at disassembly, install a new
seal.
OVERDRIVE SHIFT RAIL
DISASSEMBLY
1. Compress the lockup rail spring, pressing it away
from the "C" washer (83) Figure (2) and remove
the "C" washer.
2. Pull the shift rail shaft out of the shift f ork and
remove the spring and plain washer.
NOTE: The retractor spring should have a free
length of 2-3/4" and 1-21/32" under load of 12 lbs.
The lockup rail spring has a free length of 1-3/8"
and 15/16" under load of 8 lbs.
REASSEMBLY OF OVERDRIVE
HOUSING
1. Install the overdrive mainshaft rear bearing and rear
bearing lock ring.
2. Install a new oil seal in the overdrive rear bearing
retainer using Hydra-Matic Rear Bearing Retainer
Oil Seal Installer J-1354.
3. Before installing the shift shaft in the overdrive
housing, coat the shift shaft oil seal counterbore with
white lead and tap in a new oil seal. Dip the threaded
end of the shift shaft in liquid soap, and using care,
push the shaft through the new seal, turn the shaft so
that the shifter lug will be in an upright position.
I NSTALLATION OF ADAPTER PLATE, SOLE-
NOID PAWL, SUN GEAR CONTROL PLATE
AND BLOCKER, SOLENOID, SUN GEAR
SHIFT RAIL AND FORK
1. Install one of the overdrive housing attach.ing
screws to hold the adapter in position. Install the
solenoid pawl, sun gear control plate and blocker
assembly, Figure 11.
2. Install the adapter lock ring (large), Figure 10.
3. Install the solenoid by turning the solenoid counter-
clockwise one quarter turn, Figure 9, and before
installing the cap screws pull straight out on sole-
noid. If the solenoid can be pulled out, the ball at the
end of the solenoid rod was improperly installed
(not locked in the pawl).
4. Install the locking rail spring, "C" washer and plain
washer on the shift rail and fork assembly.
5. Install the fork in the sun gear shift collar, and while
holding the shift fork, shift rail and sun gear togeth-
er, slide the sun gear onto the main shaft and the
shifter rod into the hole in the overdrive adapter.
INSTALLATION OF CLUTCH CAM, PINION
CAGE AND OVERDRIVE MAINSHAFT
1. Install the clutch cam and pinion cage, attach the
clutch c a m to the pinion cage
