Baulk Ring Clearance for Double Cone Synchronizer (4th)

• 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.

2.

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

• 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 (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.

2.

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

3.

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