INSPECTION AFTER DISASSEMBLY
Shift Control
If the contact surface on striking lever, fork rod, shift fork, etc. has
excessive wear, abrasion, bend, or any other damage, replace the
components.
Gear and Shaft
If the contact surface on each gear, main shaft, main drive gear, and
counter shaft, etc. has damage, peeling, abrasion, dent, bent, or any
other damage, replace the components.

Synchronizer
If the contact surface on coupling sleeve, synchronizer hub, and
shifting insert has damage or abrasion, replace the components.
Coupling sleeve and synchronizer hub shall move smoothly.
If the cam surface on baulk ring or contact surface on insert has
damage or excessive wear, replace with a new one.
If spread spring is damaged, replace with a new one.
Baulk Ring Clearance
Single cone synchronizer (5th and 6th)
–Push baulk ring on the cone and measure baulk ring back sur-
face clearance at two locations or more on opposite sides, find
the average value, and replace it if it is outside the limit value.
Double cone synchronizer (4th)
Follow the instructions below and inspect the clearance of the
outer baulk ring, synchronizer cone, inner baulk ring.
CAUTION:
Clearances “A” and “B” of the outer baulk ring, synchro-
nizer cone, and inner baulk ring are controlled as a set, so if
the clearance is outside the limit value, replace the syn-
chronizer assembly.

1. Using a dial indicator, 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.
Triple cone synchronizer (1st, 2nd and 3rd)
Check clearance for outer baulk ring, synchronizer cone and
inner baulk ring of triple cone synchronizer following the direc-
tion.
NOTE:
Outer baulk ring, synchronize cone and inner baulk ring, three
control “clearance A, B and C” as a three-piece suite. If the
value exceeds the limit value, replace them as a three-piece
suite.
1. Using feeler gauge put and press baulk ring on gear taper cone,
and then measure “clearance A” at more then 2 diagonal points,
and calculate the average.
2. Using feeler gauge measure “clearance B” at more than 2 diago-
nal positions, and calculate the average.Clearance A
