CLEANING AND INSPECTION
TRANSAXLE
Clean the gears, bearings, shafts, synchronizers,
thrust washers, oil feeder, shift mechanism, gear
case, and bellhousing with solvent. Dry all parts
except the bearings with compressed air. Allow thebearings to either air dry or wipe them dry with
clean shop towels.
Inspect the gears, bearings, shafts and thrust
washers. Replace the bearings and cups if the rollers
are worn, chipped, cracked, flat spotted, or brin-
nelled, or if the bearing cage is damaged or distorted.
Replace the thrust washers if cracked, chipped, or
worn. Replace the gears if the teeth are chipped,
cracked, or worn thin. Inspect the synchronizers.
Replace the sleeve if worn or damaged in any way.
Replace the stop rings if the friction material is
burned, flaking off, or worn. Check the condition of
the synchro struts and springs. Replace these parts if
worn, cracked, or distorted.
SYNCHRONIZER
CLEAN
Do not attempt to clean the blocking rings in sol-
vent. The friction material will become contaminated.
Place synchronizer components in a suitable holder
and clean with solvent. Air dry.
INSPECT
Proper inspection of components involve:
²Teeth, for wear, scuffed, nicked, burred, or bro-
ken teeth
²Struts, for wear or distortion
²Springs, for distortion, cracks, or wear
If any of these conditions exist in these compo-
nents, replace as necessary.
ADJUSTMENTS
GEARSHIFT CROSSOVER CABLE
Before replacing the gearshift cables for a hard-
shifting complaint, disconnect both cables at the
transaxle. Then, from the driver's seat, manually
operate the gearshift lever through all gear ranges. If
the gearshift lever moves smoothly, the cable(s)
should NOT be replaced. If the gear lever binds
replace the cable that is causing the binding condi-
tion. If the problem still exists, check the crossover
cable adjustment (Fig. 210).
(1) Working over the left front fender, remove the
auxiliary vent from the selector shaft housing (Fig.
211).
(2) Locate the gearshift lock pin that has been
included in the new vehicle packet located in the
glove box.
(3) Place transaxle gearshift in the neutral posi-
tion.
(4) Insert lock pin (so long end is down) into same
threaded hole (Fig. 212). A hole in the selector shaft
will align with the lock pin, allowing the lock pin to

BEARING ADJUSTMENT PROCEDURE
The A-598 (T-750) transaxle has two bearing
adjustment procedures that must be performed if the
transaxle case or related components have been
replaced. If the intermediate shaft, and/or bearing
cups and cones have been replaced, you must per-
form the intermediate shaft preload shim adjust-
ment. If the differential case, cups or cones have

snow chain or other type of traction aid is not
to be used on the compact spare tire.
RADIAL-PLY TIRES
Radial-ply tires improve handling, tread life, ride
quality and decrease rolling resistance.
Radial-ply tires must always be used in sets of four
and under no circumstances should they be used on
the front only. They may be mixed with a temporary
spare tire when necessary. A maximum speed of 50
MPH is recommended while a temporary spare is in
use.
Radial-ply tires have the same load-carrying capac-
ity as other types of tires of the same size. They also
use the same recommended inflation pressures.
The use of oversized tires, either in the front or
rear of the vehicle, can cause vehicle drive train fail-
ure. This could also cause inaccurate wheel speed
signals when the vehicle is equipped with Anti-Lock
Brakes.
It is recommended that tires from different manu-
factures NOT be mixed. The proper tire pressure
should be maintained on all four tires. For proper
tire pressure refer to the Tire Inflation Pressure
Placard located in the glove box.
SPARE TIRE (TEMPORARY)
The temporary spare tire is designed for emer-
gency use only. The original tire should be repaired
and reinstalled at the first opportunity, or replaced
with a new. Do not exceed speeds of 50 MPH when
the temporary spare tire is in use on the vehicle.
Refer to the Owner's Manual for complete details.
TIRE INFLATION PRESSURES
WARNING: OVER OR UNDER INFLATED TIRES
CAN AFFECT VEHICLE HANDLING. THE TIRE CAN
FAIL SUDDENLY, RESULTING IN LOSS OF VEHICLE
CONTROL.
Under inflation causes rapid shoulder wear of the
tire tread and tire flexing. This can result in failure
of the tire. (Fig. 2).
Over inflation causes rapid center wear and loss of
the tire's ability tocushion shocks (Fig. 3).
