CONVERTER STALL TEST
Stall test consist of determining maximum engine
speed obtained at full throttle in “D” and “R”
positions. This test checks torque converter stator
overrunning clutch operation, and holding ability of
transaxle clutches and low-reserve brake.
Caution
During this test, make sure that no one stand in
front of or behind vehicle.
1. Check transaxle fluid level. Fluid should be at
normal operating temperature [70-80°C (160-
18O”F)j. Engine coolant should also be at normal
operating temperature
[80-90°C (180-19O”F)l.
2. Apply chocks to both rear wheels.
3. Attach engine tachometer.
4. Apply parking and service brakes fully.
5. Start engine.
6. With selector lever in “D” position, depress
accelerator pedal fully to read engine maximum
rpm. Do not hold throttle wide open any longer
than is necessary to obtain maximum engine
rpm reading, and never longer than 5 seconds at
a time. If more than one stall test is required,
operate engine at approximatey 1,000 rpm in
TRANSAXLE CONTROL
neutral for 2 minutes to cool transaxle fluid
between tests.
Stall speed: 1,800-3,200
rpm
7.Place selector lever to “R” position and perform
stall test by the same procedure as in foregoing
item.
Stall Speed Above Specification in “D”
If stall speed is higher than specification, rear clutch
or overrunning clutch of transaxle is slipping. In this
case, perform hydraulic test to locate cause of
slippage.
Stall Speed Above Specification in “I?”
If stall speed is higher than specification, front
clutch of transaxle or low-reverse brake is slipping. In this case, perform hydraulic test to locate cause
of slippage.
Stall Speed Below Specification in “D” and “R”
If stall speed is lower than specification, insufficient
engine output or faulty torque converter is sus-
pected. Check for engine misfiring, ignition timing,
valve clearance etc. If these are good, torque
converter is faulty. Svmotom

SERVICE POINTS OF REMOVAL MZ3LMU
15. REMOVAL OF DRIVE SHAFT (R.H.)
(1) Use the general service tool to push out the drive shaft
from the front hub.
(2) Insert a pry bar at the projection part and remove the drive shaft
(R.H.) from the transaxle.
Caution
Do not pull out the drive shaft; doing so will
damage the T.J.; be sure to use the pry bar.
16. DISCONNECTION OF DRIVE SHAFT (L.H.)
(1) Disconnect the inner shaft assembly from the transaxle
by lightly tapping the T.J. case with a plastic hammer,
etc.
(2) Suspend the drive shaft with wire or something similarso that there are no sudden bends in the joints.
SERVICE POINTS OF INSTALLATIONMZ3LOAN
24. INSTALLAnON OF TRANSAXLE ASSEMBLY
First install the torque converter on the transaxle and then
install the transaxle assembly on the engine.
Caution
Be sure to install the torque converter on the transaxle
first.
lf it is first installed on the engine, the oil seal on
the transaxle side will be damaged.
15. INSTALLATION OF DRIVE SHAFT
(R-H.)
Install the drive shaft nut for the drive shaft (R.H.) in the
following way.
(1) Be sure to install1 the washer and drive shaft nut in the
specified direction.
(2) After installing the wheel, lower the vehicle to the ground and finally tighten the drive shaft nut.
(3) If the position of the cotter pin holes does not match,tighten the nut up to 260 Nm (188
ft.lbs.1 in maximum.
(4) Install the cotter pin in the first matching holes and bend it securely.

SERVICE ADJUSTMENT PROCEDURES
WHEEL BEARING END PLAY ADJUSTMENTmw

1.Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2.If there is any play, remove the hub cap, cotter pin, and lock
cap, and then loosen the lock nut.
3.After tightening the lock nut to 20 Nm (14 ft.lbs.1, turn the
hub a few times to seat it to the bearing.
4. In order to seat the bearing properly, turn the hub (brake drum) 180” or more and then return it 360” or more; repeat
this procedure again three or more times.
5. Return the lock nut to 0 Nm
(0 ft.lbs.).
6.After tightening the lock nut at a torque of 10 Nm (7 ft.lbs.1,
rotate the hub again in the same way as described in step 4
so as to seat the bearing.
7. Then once again tighten the lock nut to 10 Nm (7
ft.lbs.).
8. Install the lock cap and cotter pin. If the position of the cotter pin is not matched with the
holes of the lock cap, reposition the lock cap so that the
holes align. If this can not be accomplished, back off the nut
by not more than 15”.
Caution
Check to be sure that the lock nut cannot be loosened
manually.
9.After setting the cotter pin in place, seat the bearing in the
same manner as in step 4.

10. After securing the wheel nuts, attach a spring balance and
rope to the hub bolt, and, pulling at a 90” angle from the
hub bolt, measure to determine whether or not the rotary-
sliding resistance of the rear hub is the standard value.
Standard value: Rear hub rotary-sliding resistance
When a new bearing is used 14
N (3.08 Ibs.) or less
When the bearing is reused 11
N (2.42 Ibs.) or less
NOTE
If the standard value is exceeded, the lock nut should be
tightened or the bearing replaced.
11. Check the bearing’s end play.
Place a dial gauge against the hub surface; then move the
hub in the axial direction and check whether or not there is
end play.
Limit: 0 mm (0 in.)
12. If there is any play, the lock nut should be tightened or the
bearing replaced.
13. After checking, be sure the hub rotates smoothly and that
the cotter pin is correctly installed.

1. Inspect the play of the bearings while the vehicle is jacked up and resting on floor jack.
2. Remove the hub cap and then release the parking brake.
3. Remove the caliper assembly and the brake disc.
4. Check the bearing’s end play.
Place a dial gauge against the hub surface; then move the
hub in the axial direction and check whether or not there is
end play.
Limit: 0.05 mm (.0020 in.) or less
NOTE
If the limit value is exceeded, the lock nut should be
tightened to the specified torque and check the end play
again.
5.Replace the rear hub bearing unit if an adjustment cannot
be made to within the limit.
