< DISASSEMBLY AND ASSEMBLY >
[6MT: FS6R31A]
GEAR COMPONENTS
Check the clearance between outer baulk ring, synchronizer cone,
and inner baulk ring as follows.
CAUTION:
The clearances (A) and (B) are controlled with outer baulk
ring, synchronizer cone, and inner baulk ring as a set.
Replace them as a set if the clearances are outside the limit
value.
1.
Measure the clearance (A) at 2 points or more diagonally oppo-
site using a dial indicator and Tool. Then calculate the mean
value.
2.
Measure the clearance (B) at 2 points or more diagonally oppo-
site using a feeler gauge. Then calculate the mean value.
• Triple Cone Synchronizer (2nd)
Check the clearance between outer baulk ring, synchronizer cone,
and inner baulk ring as follows.
CAUTION:
The clearances (A), (B) and (C) are controlled with outer baulk
ring, synchronizer cone, and inner baulk ring as a set.
Replace them as a set if the clearances are outside the limit
value.

1.
Measure the clearance (A) at 2 points or more diagonally oppo-
site using a feeler gauge when pressing baulk ring toward clutch
gear taper cone. Then calculate the mean value.
2.
Measure the clearance (B) at 2 points or more diagonally oppo-
site using a feeler gauge. Then calculate the mean value.
3.
Measure the clearance (C) at 2 points or more diagonally oppo-
site using a feeler gauge when pressing baulk ring toward clutch
gear taper cone. Then calculate the mean value.
BEARINGS
If the bearing does not rotate smoothly or the contact surface on ball
or race is damaged or peeled, replace with new ones.
