Reassembly
1) Clean all components thoroughly, inspect them for
any abnormality and replace with new ones as
necessary.
2) Check clearance “a” between synchronizer ring (2)
and gear (1), key slot width “b” in synchronizer ring
and each chamfered tooth of gear and synchronizer
ring and replace with new one, if necessary. Also,
check gear tooth.
Clearance “a” between synchronizer ring and
gear
Standard: 1.0 – 1.4 mm (0.040 – 0.055 in.)
Service limit: 0.5 mm (0.020 in.)
Key slot width “b”
Standard: 10.0 – 10.2 mm (0.394 – 0.401 in.)
Limit: 10.45 mm (0.411 in.)
3) To ensure lubrication of input shaft (1), air blow oil
holes (2) and make sure that they are free from any
obstruction.4) Fit high speed synchronizer sleeve (4) to hub (3),
insert 3 keys (2) in it and then set springs (1) as
shown in figure.
NOTE
• No specific direction is assigned to high
speed synchronizer sleeve or each key but
it is assigned as assembly.
• Size of high speed synchronizer sleeve,
hub, keys and springs are the smaller than
those of low speed one.

6) Install 3rd gear needle bearing (4), apply oil to it,
then install 3rd gear (1) and synchronizer ring (2).
7) Drive in high speed sleeve & hub assembly (3) by
using special tool and hydraulic press.
NOTE
• While press-fitting sleeve & hub, make
sure that synchronizer ring key slots are
aligned with keys (5) in sleeve & hub
assembly.
• Check free rotation of 3rd gear after press-
fitting sleeve & hub assembly.
• Synchronizer rings for 3rd and 4th are
identical.

Special tool
(B): 09913–845108) Install circlip (1) and confirm that circlip is installed in
groove securely. Install needle bearing (2) of apply
oil to it and then install synchronizer ring (3) and 4th
gear (4).
9) Press-fit left bearing (2) by using special tool and
hydraulic press.
Special tool
(A): 09913–80113
10) Using the same special tool at step 9), drive in 5th

Countershaft Disassembly and ReassemblyS6RW0D5206021
Disassembly
1) Drive out left bearing cone (2) with 4th gear (3) by
using puller (4) and hydraulic press.
CAUTION!
• Use puller and hydraulic press that will
bear at least 5 ton (11,000 lb) safely.
• To avoid tooth damage, support 4th gear
(3) at flat side of puller.

2) Apply puller (5) to 2nd gear (4) and drive out 3rd &
4th gear spacer (2) and 3rd gear (3) together with
2nd gear by using hydraulic press. Needle bearing
would come out with 2nd gear.
CAUTION!
• If compression exceeds 5 ton (11,000 lb),
release compression once, reset bearing
puller and then continue press work again.
• To avoid gear tooth from being damaged,
support it at flat side of bearing puller.

3) Take out 2nd synchronizer outer ring, center cone
and inner ring.
4) Using special tool, remove circlip (1).
NOTE
Correct tool tips to be flat to facilitate
removal of circlip.

Special tool
(A): 09900–06107
5) Apply puller (3) to 1st gear (2) and drive out low
speed synchronizer sleeve & hub assembly (1) with
1st gear by using hydraulic press.
CAUTION!
To avoid gear tooth from damage, support it
at flat side of bearing puller.

6) Disassemble synchronizer sleeve & hub assembly.
7) Take out 1st gear needle bearing from shaft.
8) In order to remove right bearing (1) from
countershaft, grind with a grinder (2) one part “a” of
right bearing (1) as illustrated till it becomes thin.
CAUTION!
Be careful not to grind too far not to damage
the shaft (3).

9) Break with a chisel (1) the thin ground right bearing
(2) and it can be removed.
Reassembly
1) Clean all components thoroughly, inspect them for
any abnormality and replace with new one as
necessary.
2) Check clearance “a” between synchronizer ring (2)
and gear (1), key slot width “b” in synchronizer ring
and each chamfered tooth of gear and synchronizer
ring and replace with new one, if necessary. Also,
check gear tooth.
Clearance “a” between synchronizer ring and
gear
Standard: 1.0 – 1.4 mm (0.040 – 0.055 in.)
Service limit: 0.5 mm (0.020 in.)
Key slot width “b”
Standard: 10.0 – 10.2 mm (0.394 – 0.401 in.)
Limit: 10.45 mm (0.411 in.)3) Put the synchronizer outer ring (1), inner ring (3) and
the cone (2) together and then measure the step
difference between the outer ring and the inner ring.
And also check each chamfered tooth of gear and
synchronizer ring and replace with new one, if
necessary. Also, check gear tooth.
Difference between synchronizer outer ring and
inner ring (2nd)
Standard “b”: 0.95 – 1.25 mm (0.036 – 0.048 in.)
Service limit “b”: 0.5 mm (0.019 in.)
4) To ensure lubrication of countershaft (1), air blow oil
holes (2) and make sure that they are free from any
obstruction.

5) Fit low speed synchronizer sleeve (4) to hub (3),
insert 3 keys (2) in it and then set springs (1) as
shown in figure.
NOTE
• No specific direction is assigned to each

Gear Shift Shaft and Fork InspectionS6RW0D5206024
1) Using feeler gauge, check clearance between fork
(1) and sleeve (2) and replace those parts if it
exceeds limit of 1.0 mm (0.039 in.).
NOTE
For correct judgement of parts replacement,
carefully inspect contact portion of fork and
sleeve.

Clearance “a” between fork and sleeve
Service limit: 1.0 mm (0.039 in.)
