INSPECTION AFTER DISASSEMBLY
Input Shaft and Gears
Check items below. If necessary, replace them with new ones.

Damage, peeling, dent, uneven wear, bending, etc. of shaft

Excessive wear, damage, peeling, etc. of gears
Synchronizer
Check items below. If necessary, replace them with new ones.

Damage and excessive wear of contact surfaces of coupling
sleeve, synchronizer hub and shifting insert

Coupling sleeve and synchronizer hub must move smoothly.

If any crack, damage, or excessive wear is found on cam face of
baulk ring or working face of insert, replace it.
BAULK RING CLEARANCE

Single-cone synchronizer (4th, 5th and 6th)
Push baulk ring on the cone, and measure the clearance
between baulk ring and cone. If measurement is below limit,
replace it with a new one.

Double-cone synchronizer (3rd)
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 then calculate mean value.
