(1) Place drive pinion shaft assembly on right hand
transmission main case without shim and tighten bear-
ing mounting bolts.
(2) Inspection and adjustment of ST
NOTE:
Loosen the two bolts and adjust so that the scale indi-
cates 0.5 correctly when the plate end and the scale end
are on the same level.
Tighten the two bolts.

(3) Position the ST by inserting the knock pin of ST into
the knock hole in the transmission case.
(4) Slide the drive pinion gauge scale with finger tip
and read the value at the point where it matches with
the end face of drive pinion.


C: Adjust clearance to zero without shim.
(5) The thickness of shim shall be determined by add-
ing the value indicated on drive pinion to the value
indicated on the ST. (Add if the number on drive pinion
is prefixed by + and subtract if the number is prefixed
by.)

Select one to three shims from the next table for the value
determined as described above and take a shim thickness
which is closest to the said value.

case.
CAUTION:
Be careful not to fold the sealing lip of oil seal.
NOTE:
Wrap the left and right splined sections of axle shaft with
vinyl tape to prevent scratches.

4) Install needle bearing and oil seal onto the front of
transmission main shaft assembly

4, and position in left
side transmission case.
CAUTION:
Wrap clutch splined section with vinyl tape to pre-
vent damage to oil seal.
Apply grease (Unilube #2 or equivalent) to the seal-
ing lip of oil seal.
NOTE:
Align the end face of seal with surface A of left side
transmission main case when installing oil seal.
Be careful not to drop oil seal when installing right side
transmission main case.
Make sure straight pin is positioned in hole in needle
bearing’s outer race.

1. Manual Transmission and
Differential
Symptom and possible cause Remedy
1. Gears are difficult to intermesh.
The cause for difficulty in shifting gears can be classified into two kinds: one is malfunction of the gear shift system and the
other is malfunction of the transmission. However, if the operation is heavy and engagement of the gears is difficult, defective
clutch disengagement may also be responsible. Check whether the clutch is correctly functioning, before checking the gear
shift system and transmission.
(a) Worn, damaged or burred chamfer of internal spline of
sleeve and reverse driven gearReplace.
(b) Worn, damaged or burred chamfer of spline of gears Replace.
(c) Worn or scratched bushings Replace.
(d) Incorrect contact between synchronizer ring and gear
cone or wearCorrect or replace.
2. Gear slips out.
(1) Gear slips out when coasting on rough road.
(2) Gear slips out during acceleration.
(a) Defective pitching stopper adjustment Adjust.
(b) Loose engine mounting bolts Tighten or replace.
(c) Worn fork shifter, broken shifter fork rail spring Replace.
(d) Worn or damaged ball bearing Replace.
(e) Excessive clearance between splines of synchronizer hub
and synchronizer sleeveReplace.
(f) Worn tooth step of synchronizer hub (responsible for slip-
out of 3rd gear)Replace.
(g) Worn 1st driven gear, needle bearing and race Replace.
(h) Worn 2nd driven gear, needle bearing and race Replace.
(i) Worn 3rd drive gear and bushing Replace.
(j) Worn 4th drive gear and bushing Replace.
(k) Worn reverse idler gear and bushing Replace.
3. Unusual noise comes from transmission.
If an unusual noise is heard when the vehicle is parked with its engine idling and if the noise ceases when the clutch is
disengaged, it may be considered that the noise comes from the transmission.
(a) Insufficient or improper lubrication Lubricate or replace with specified oil.
(b) Worn or damaged gears and bearings Replace.
NOTE: If the trouble is only wear of the tooth surfaces, merely
a high roaring noise will occur at high speeds, but if any part
is broken, rhythmical knocking sound will be heard even at
low speeds.
