20) Support transmission with a garage jack.
CAUTION:
Before moving engine away from transmission,
check to be sure no work has been overlooked.
Doing this is very important in order to facili-
tate re-installation and because transmission
lowers under its own weight.

4) Rotating parts should be coated with oil prior to
assembly.
5) All disassembled parts, if to be reused, should
be reinstalled in the original positions and direc-
tions.
6) Gaskets and lock washers must be replaced
with new ones.
7) Liquid gasket should be used where specified
to prevent leakage.
8) Fill transmission gear oil through the oil level
gauge hole up to upper point level gauge. 1-5 [G9A1].>
B: INSPECTION
Disassembled parts should be washed clean first
and then inspected carefully.
1) Bearings
Replace bearings in the following cases:IBearings whose balls, outer races and inner
races are broken or rusty.
IWorn bearings
IBearings that fail to turn smoothly or make
abnormal noise when turned after gear oil lubrica-
tion.
IThe ball bearing on the rear side of the drive
pinion shaft should be checked for smooth rotation
before the drive pinion assembly is disassembled.
In this case, because a preload is working on the
bearing, its rotation feels like it is slightly dragging
unlike the other bearings.

(B) Ball bearing
IBearings having other defects
2) Bushing (each gear)
Replace the bushing in the following cases:
IWhen the sliding surface is damaged or abnor-
mally worn.
IWhen the inner wall is abnormally worn.
3) Gears
IReplace gears with new ones if their tooth sur-
faces are broken, damaged, or excessively worn.
ICorrect or replace if the cone that contacts the
baulk ring is rough or damaged.
ICorrect or replace if the inner surface or end
face is damaged.
4) Baulk ring
Replace the ring in the following cases:
IWhen the inner surface and end face are dam-
aged.
IWhen the ring inner surface is abnormally or
partially worn down.

17) Place the transmission with case left side fac-
ing downward and put ST1 on bearing cup.
18) Screw retainer assembly into left case from
the bottom with ST2. Fit ST3 on the transmission
main shaft. Shift gear into 4th or 5th and turn the
shaft several times. Screw in the retainer while
turning ST3 until a slight resistance is felt on ST2.
This is the contact point of hypoid gear and drive
pinion shaft. Repeat the above sequence several
times to ensure the contact point.

19) Remove weight and screw in retainer without
O-ring on the upper side and stop at the point
where slight resistance is felt.
NOTE:
At this point, the backlash between the hypoid gear
and drive pinion shaft is zero.

20) Fit lock plate. Loosen the retainer on the lower
side by 1-1/2 notches of lock plate and turn in the
retainer on the upper side by the same amount in
order to obtain the backlash.
NOTE:
The notch on the lock plate moves by 1/2 notch if
the plate is turned upside down.
21) Turn in the retainer on the upper side addition-
ally by 1 notch in order to apply preload on taper
roller bearing.
22) Tighten temporarily both the upper and lower
lock plates and mark both holder and lock plate for
later readjustment.
23) Turn transmission main shaft several times
while tapping around retainer lightly with plastic
hammer.

26) After checking the tooth contact of hypoid
gears, remove the lock plate. Then loosen retainer
until the O-ring groove appears. Fit O-ring into the
groove and tighten retainer into the position where
retainer has been tightened in.
Tighten lock plate.
NOTE:
Carry out this job on both upper and lower retain-
ers.

protrusion from transmission main case surface
and select the proper plate in the following table:

NOTE:
Before measuring, tap the end of main shaft with
a plastic hammer lightly in order to make the clear-
ance zero between the main case surface and the
