Baulk Ring Clearance for Double Cone Synchronizer (4th)
• Check the clearance between outer baulk ring (1), synchronizer
cone (2), and inner baulk ring (3) 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 (B) and puller (C) [SST: ST30031000
(J-22912-01)]. And then calculate mean value.
2.
Measure the clearance “B” at 2 points or more diagonally oppo-
site using a feeler gauge (A). And then calculate mean value.
