AUTOMATIC TRANSAXLE - Transaxle Assembly
23-67
DISASSEMBLY
Caution1. The automatic transaxle consists of high-precision
parts and utmost care must be exercised during
disassembly and reassembly to prevent damage to the
parts.
2.Place a rubber mat on the workbench and keep it cleanat all times.
3.Do not use cotton work gloves or waste cloth for the
disassembly job. Use nylon cloth or paper towel if
necessary.4. Clean all disassembled parts. Commercially available
detergent may be used to clean the
metalllic parts;
however, be sure to dry them completely with air.
5. Clean the clutch disc, plastic thrust plates, and rubberparts with ATF (automatic transmission fluid) to pre-
vent adhesion of dust and dirt.
6.If the transaxle is damaged, the cooler system should
also be disassembled and cleaned.(1) Remove the torque converter.
(2) Install the dial indicator to the transaxle case and measure
the end play in the input shaft.
(3) Remove brackets.
(4) Remove the oil level gauge and oil level gauge guide.
(5) Remove pulse generators A and B
(6) Remove the manual control lever and then remove the
inhibitor switch.
(7) Remove the speedometer drive gear assembly.

Caution
1.The gasket, O-ring, and oil seal should never be reused.Whenever they have been removed, they must be
replaced with new ones. (Note: The rubber used in theoil level gauge does not require replacement.)
2. Never use grease other than petrolatum.
3.Be sure to apply ATF to the friction elements and rotary
and sliding surfaces before reassembly.
A new clutch disc and brake disc should be dipped inATF for more than 2 hours before installation.
4. Do not use sealant or adhesive for gaskets.
5.When replacing a bushing, replace the whole assemblycontaining that bushing.
6.Do not use cotton work gloves or waste cloth for the
reassembly job. Use nylon cloth or paper towel if
necessary.7. Replace oil in the cooler.
(I) Using the special tool, press-fit the drive shaft oil seal into
position.
(2) Using the special tool, press-fit the outer race into the
transaxle case.
(3) Install the transfer shaft.

STEERING 2 Service Adjustment Procedures37A-5
13FOOOi13FOOO3SERVICE ADJUSTMENT PROCEDURES
STEERING WHEEL FREE PLAY CHECKM37FABI
1.With engine running (hydraulic operation), set front wheels
straight ahead.
2. Measure the play on steering wheel circumference before
wheels start to move when slightly moving steering wheel
in both directions.
Limit: 30 mm (1.2 in.)
3:When the play exceeds the limit, check for play on steering
shaft connection and steering linkage. Correct or replace.
4. If the free play still exceeds the limit value set steering
wheel straight ahead with engine stopped. Load 5 N
(1 lb.)
towards steering wheel circumference and check play.
Standard values (steering wheel play with engine
stopped): 11 mm
(.43 in.)
If the play exceeds the standard value, remove steering
gear box and check total pinion torque.
STEERING ANGLE CHECKM37FDBK1. Set front wheels on turning radius gauge and measure
steering angle.
Standard values:Inner wheel
33”45’ k 2”
Outer wheel
28”21’2. When not within the standard value, it is probably a toe
problem. Adjust toe (refer to GROUP 33A
- Service
Adjustment Procedures) and recheck.
TIE ROD END BALL JOINT VARIATION CHECK
(SHAFT DIRECTION)M37FPAF1. Hold the ball joint with pliers.
2.Set a caliper gauge as illustrated and measure the displace-
ment with the ball stud compressed.
Limit: 1.5 mm
(.059 in.)
3. If the measured displacement exceeds the limit, replace
the tie-rod end.
Caution
Even if the variation is within the limit, check ball jointstarting torque.

1. Disconnect tie rod and knuckle with special tool.~
LJ2. Move ball joint stud several times and install nut on stud.
Measure ball joint starting torque.
Standard value:
0.5 - 3.0 Nm (4 - 26 in.lbs.1
1.0 - 3.0 Nm (9 - 26 in.lbs.)3. When starting torque exceeds the standard value, replace
tie rod end.
4.When the starting torque is under the standard value, check
for play or ratcheting in ball joint.
If none of these, it is still
serviceable.
STEERING WHEEL CENTERINGM37FNAI
SIMPLIFIED STEERING WHEEL CENTERINGDetermining Steering Wheel’s Off Center
1. For the road test, take along chalk or tape and a ruler.
2. Drive straight ahead on an uncambered level surface.
3. When the vehicle’s wheels are pointing straight ahead,
mark the steering wheel hub and column cover with a chalk
or tape line.
4. Stop the vehicle and line up the marks on the hub and
column cover.
5. Place a tape strip
01 mark on the steering wheel rim.
6.Hold a ruler next to the rim as shown in the illustration, and
then steer the steering wheel until it is in the desired
centered position.
7.Record the distance the strip or mark on the rim has moved.
This is how far the steering wheel is off center. If it is more
than 16 mm
(518 in.) off center, it can be centered by
indexing it ten degrees towards the center.
Indexing Steering Wheel to Center It
The steering wheel shaft has 36 splines, allowing the steering
wheel to be indexed in ten-degree increments.
1. Remove the steering wheel.
2.Without disturbing the position of the steering wheel shaft,
re-install the wheel as near on-center as possible.

PRECISION STEERING WHEEL CENTERINGIn general, the tie rods are adjusted to steer the front wheels in
the same direction that the steering wheel is off center. If the
steering wheel is off center to the left, center it by adjusting the
tie rods to make the front wheels steer toward the left, and vice
versa.
1. Mark the tie rods and tie rod ends with chalk before
loosening the lock nuts.
2. Hold the tie rod with a wrench and loosen the lock nut.
3.Hold the tie rod end with a wrench and turn the tie rod the
desired number of turns.
