MAINSHAFT AND GEAR

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 condi-

tions of the gears.

SYNCHRONIZER

Synchronizer Hub and Coupling Sleeve

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.

Baulk Ring and Spread Spring

Check items below. If necessary, replace them with new ones.
• 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 for Double Cone Synchronizer (1st)

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.

Measure the clearance “A” at 2 points or more diagonally oppo-
site using a dial indicator. And then calculate mean value.

Measure the clearance “B” at 2 points or more diagonally oppo-
site using a feeler gauge. And then calculate mean value.

Baulk Ring Clearance for 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.

Measure the clearance “A” at 2 points or more diagonally oppo-
site using a feeler gauge (B) when pressing outer baulk ring (1),
synchronizer cone (2), and inner baulk ring (3) toward gear taper
cone (C). And then calculate mean value.
