Main Shaft Inspection

S6JB0A5226023

• Check clearance “a” between synchronizer outer ring

(1) and gear (2) while lightly pushing synchronizer ring
by hand, and also check chamfered tooth of gear and
synchronizer outer ring. Also, check gear tooth.
Replace with new one if necessary.

Clearance “a” between synchronizer outer ring
and gear (4th, 5th and reverse)
Standard: 1.0 – 1.5 mm (0.040 – 0.059 in.)
Service limit: 0.7 mm (0.028 in.)

• Put synchronizer outer ring (1), inner ring (2) and

center cone (3) together and then measure step
difference “b” between outer ring and inner ring using
straight edge (4). And also check chamfered tooth of
gear and synchronizer ring. Also, check gear tooth.
Replace with new one if necessary.

Difference “b” between synchronizer outer ring
and center cone (1st)
Standard: 0.4 – 0.8 mm (0.016 – 0.031 in.)
Service limit: 0.2 mm (0.008 in.)

• Check clearance “c” between synchronizer outer ring

(1) and center cone (2). If clearance exceeds limit,
replace with new one.

Clearance “c” between synchronizer outer ring
and center cone (1st, 2nd and 3rd)
Standard: 0.41 – 0.7 mm (0.016 – 0.028 in.)
