COUNTER SHAFT ASSEMBLY
DISASSEMBLY
1) Drive out left bearing cone (2) with 4th gear (3) from counter
shaft (1) by using puller (4) and press.
2) Apply puller (5) to 2nd gear (4) and drive out 3rd & 4th gear
spacer (2) and 3rd gear (3) together with 2nd gear from
counter shaft (1) by using press. Take out needle bearing of
separated steel cage type from counter shaft.
3) Take out 2nd synchronizer outer ring, center cone and inner
ring.
4) Using circlip pliers, remove circlip (1).
5) Apply puller (3) to 1st gear (2) and drive out low speed syn-
chronizer sleeve & hub assembly (1) with gear by using
press.

7) Take out needle bearing from shaft.CAUTION:
 Use puller and press that will bear at least 5 ton (11,000
lb) safely.
 To avoid tooth damage, support 4th gear at flat side of
puller.
CAUTION:
 If compression exceeds 5 ton (11,000 lb), release com-
pression once, reset puller support and then continue
press work again.
 To avoid gear tooth from being damaged, support it at
flat side of bearing puller.
CAUTION:
To avoid gear tooth from being damaged, support it at flat
side of bearing puller.

(1) and press.
INSPECTION AND REASSEMBLY
1) Clean all components thoroughly, inspect them for any
abnormality and replace with new ones as necessary.
2) If synchronizer parts need to be repaired, check clearance
“a” between ring (2) and gear (1), each chamfered tooth of
gear, ring and sleeve, then determine parts replacement.
Clearance between synchronizer ring and gear
Standard “a” : 1.0 – 1.4 mm (0.039 – 0.055 in.)
Service limit “a” : 0.5 mm (0.019 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
Standard “b” : 1.0 – 1.4 mm (0.039 – 0.055 in.)
Service limit “b” : 0.5 mm (0.019 in.)
4) To ensure lubrication, air blow oil holes (1) and make sure
that they are free from any obstruction.
