When installing the clutch cover on the flywheel, position
the clutch cover so that there is a gap of 120°or more
between“0”marks on the flywheel and clutch cover. (“0”
marks indicate the directions of residual unbalance.)
Note the front and rear of the clutch disc when installing.
Tighten clutch cover installing bolts gradually. Each bolt
should be tightened to the specified torque in a crisscross
fashion.

3. Performance Test
A: STALL TEST
1. GENERAL
The stall test is of extreme importance in diagnosing the
condition of the automatic transmission and the engine. It
should be conducted to measure the engine stall speeds in
all shift ranges except the P and N ranges.
Purposes of the stall test:
1) To check the operation of the automatic transmission
clutch.
2) To check the operation of the torque converter clutch.
3) To check engine performance.
2. TEST METHODS
Preparations before test:


1Check that throttle valve opens fully.


2Check that engine oil level is correct.


3Check that coolant level is correct.


4Check that ATF level is correct.


5Check that differential gear oil level is correct.


6Increase ATF temperature to 50 to 80°C (122 to 176°F)
by idling the engine for approximately 30 minutes (with
select lever set to“N”or“P”).
1) Install an engine tachometer at a location visible from
the driver’s compartment and mark the stall speed range
on the tachometer scale.
2) Place the wheel chocks at the front and rear of all
wheels and engage the parking brake.
3) Move the manual linkage to ensure it operates properly,
and shift the select lever to the 2 range.
B3M0286B
4) While forcibly depressing the foot brake pedal, gradu-
ally depress the accelerator pedal until the engine operates
at full throttle.
5) When the engine speed is stabilized, read that speed
quickly and release the accelerator pedal.
6) Shift the select lever to Neutral, and cool down the
engine by idling it for more than one minute.
7) Record the stall speed.
8) If stall speed in 2 range is higher than specifications,
forward clutch slipping on brake band slipping may occur.
To identify it, conduct the same test as above in D range.
9) Perform the stall tests with the select lever in the R
range.
CAUTION:
Do not continue the stall test for MORE THAN FIVE
SECONDS at a time (from closed throttle, fully open
throttle to stall speed reading). Failure to follow this
instruction causes the engine oil and ATF to deterio-
rate and the clutch and brake band to be adversely
affected.

Symptom and possible cause Remedy
1. Oil leakage


1Worn, scratched, or incorrectly seated front or side oil seal.
Scored, battered, or excessively worn sliding surface of com-
panion flange.Repair or replace.


2Clogged or damaged air breather. Clean, repair or replace.


3Loose bolts on differential spindle or side retainer, or incor-
rectly fitted O-ring.Tighten bolts to specified torque. Replace O-ring.


4Loose rear cover attaching bolts or damaged gasket. Tighten bolts to specified torque. Replace gasket and apply liquid
packing.


5Loose oil filler or drain plug. Retighten and apply liquid packing.


6Wear, damage or incorrectly fitting for spindle, side retainer
and oil seal.Repair or replace.
2. Seizure
Seized or damaged parts should be replaced, and also other parts should be thoroughly checked for any defect and should be
repaired or replaced as required.


1Insufficient backlash for hypoid gear. Readjust or replace.


2Excessive preload for side, rear, or front bearing. Readjust or replace.


3Insufficient or improper oil used. Replace seized part and fill with specified oil to specified level.
3. Damage
Damaged parts should be replaced, and also other parts should be thoroughly checked for any defect and should be repaired or
replaced as required.


1Improper backlash for hypoid gear. Replace.


2Insufficient or excessive preload for side, rear, or front bear-
ing.Readjust or replace.


3Excessive backlash for differential gear. Replace gear or thrust washer.


4Loose bolts and nuts such as crown gear bolt. Retighten.


5Damage due to overloading. Replace.
4. Noises when starting or shifting gears
Noises may be caused by differential assembly, universal joint, wheel bearing, etc. Find out what is actually making noise before dis-
assembly.


1Excessive backlash for hypoid gear. Readjust.


2Excessive backlash for differential gear. Replace gear or thrust washer.


3Insufficient preload for front or rear bearing. Readjust.


4Loose drive pinion nut. Tighten to specified torque.


5Loose bolts and nuts such as side bearing retainer attaching
bolt.Tighten to specified torque.
