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.

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.

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.)
