A: REMOVAL
1) Remove the manual transmission assembly
from vehicle. <Ref. to 5MT-30, REMOVAL, Manual
Transmission Assembly.>
2) Remove the transfer case with extension case
assembly. <Ref. to 5MT-43, REMOVAL, Transfer
Case and Extension Case Assembly.>
3) Remove the transmission case. <Ref. to 5MT-
55, REMOVAL, Transmission Case.>
4) Move the counter gear shaft until it touches
transmission case, and remove the snap ring with a
suitable tool.
5) Slide the washer to the rear of high-low counter
shaft, and remove the straight pin from counter
shaft.
6) Remove the counter shaft from transmission
case, taking care not to drop the counter gear and
two washers.
NOTE:
• Be careful not to damage the O-ring.
• Be careful not to drop the straight pin on front
side.
• Be careful not to drop the two needle bearings
and collar contained in counter gear.
B: INSTALLATION
1) Install the O-ring and straight pin onto counter
gear shaft.
2) Install the following parts in main case (Right-
side), and push the shaft perfectly into case.
• Counter gear shaft
• Two counter gear washers
• Two needle bearings
• Counter gear collar
• Counter gear
• Straight pin
• Snap ring
3) Install the transmission case. <Ref. to 5MT-57,
INSTALLATION, Transmission Case.>
4) Install the transfer case with extension case as-
sembly. <Ref. to 5MT-43, INSTALLATION, Trans-
fer Case and Extension Case Assembly.>
5) Install the manual transmission assembly on ve-
hicle. <Ref. to 5MT-32, INSTALLATION, Manual
Transmission Assembly.>
NOTE:
• Make sure that the cut-out end surface of counter
gear shaft does not protrude above the end surface
of the case.
• Position the cut-out portion of counter gear shaft.
C: INSPECTION
1) After installing the snap ring, measure the clear-
ance between snap ring and counter washer.
Clearance:
0.05 — 0.35 mm (0.0020 — 0.0138 in)
2) If the clearance is out of specified value, select a
snap ring and install to put clearance within speci-
fied value. <Ref. to 5MT-97, ADJUSTMENT,
Counter Gear.>

General Diagnostic Table
23.General Diagnostic Table
A: INSPECTION
1. MANUAL TRANSMISSION
Symptom
Possible cause
Corrective action
1. Gears are difficult to intermesh.
NOTE:
The cause for difficulty in shifting gears
can be classified into two kinds: one is de-
fective gear shift system and the other is
defective transmission. However, if the
operation is heavy and engagement of the
gears is difficult, defective clutch disen-
gagement 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 gear
Replace.
(b) Worn, damaged or burred chamfer of
spline of gears
Replace.
(c) Worn or scratched bushings
Replace.
(d) Incorrect contact between synchro-
nizer ring and gear cone, or wear
Rectify or replace.
2. Gear slip-out
• Gear slips out when coasting on rough
road.
• 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
sleeve
Replace.
(f) Worn tooth step of synchronizer hub
(caused by slip-out of 3rd gear)
Replace.
(g) Worn 1st driven gear and driven shaft
Replace.
(h) Worn 2nd driven gear and bushing
Replace.
(i) Worn 3rd drive gear main shaft needle
bearing
Replace.
(j) Worn 4th drive gear bushing needle
bearing
Replace.
(k) Worn 5th drive gear bushing needle
bearing
Replace.
(l) Worn reverse idler gear and bushing
Replace.
3. Noise emit from transmission.
NOTE:
If a noise is heard when the vehicle is
parked with its engine idling and if a noise
ceases when the clutch is disengaged, it
may be considered that the noise comes
from the transmission.
(a) Insufficient or improper lubrication
Lubricate with specified oil or replace.
(b) Worn or damaged gears and bearings
NOTE:
If the trouble is only wear of the tooth sur-
faces, merely a high roaring noise will oc-
cur at high speeds, but if any part is
broken, rhythmical knocking sound will be
heard even at low speeds.
Replace.
