+Measure wear of 1st and 2nd baulk ring.
a) Place baulk rings in position on synchronizer cone.
b) While holding baulk ring against synchronizer cone as far as it
will go, measure dimensions ªAº and ªBº.
Standard:
A 0.6 - 0.8 mm (0.024 - 0.031 in)
B 0.6 - 1.1 mm (0.024 - 0.043 in)
Wear limit:
0.2 mm (0.008 in)
+If dimension ªAº or ªBº is smaller than the wear limit,
replace outer baulk ring, inner baulk ring and synchro-
nizer cone as a set.
