INSPECTION AFTER DISASSEMBLY
Mainshaft and Gears
Check items below. If necessary, replace them with new ones.
●Damage, peeling, dent, uneven wear, bending, and other non-
standard conditions of the shaft.
●Excessive wear, damage, peeling, and other non-standard con-
ditions of the gears.
Synchronizer
Check items below. If necessary, replace them with new ones.
●Damage and unusual wear on 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
●Double cone synchronizer (1st and 2nd)
Check clearance of outer baulk ring, synchronizer cone, and
inner baulk ring of 1st and 2nd double cone synchronizers, fol-
lowing procedure below.
CAUTION:
Outer baulk ring, synchronizer cone, and inner baulk ring
as a set control clearance A and B. If measurement exceeds
service limit value, replace all of them as a set.
1. Using a dial gauge, measure clearance A at 2 or more points
diagonally opposite, and calculate mean value.
2. Using a feeler gauge, measure clearance B at 2 or more points
diagonally opposite, and calculate mean value.
Bearing
Check items below. If necessary, replace them with new ones.
●Damage and rough rotation of bearing
