lMeasure baulk ring wear.
a. Measure clearance between baulk ring and gear.
Clearance between baulk ring and gear:
Refer to SDS, MT-59.
lIf the clearance is less than the wear limit, replace baulk ring.
lMeasure 2nd & 3rd baulk rings wearÐTD25 engine model
only.
a. Place baulk rings in position on synchronizer cone.
b. While holding baulk rings against synchronizer cone as far as
possible, measure dimensions ``A'' and ``B''.
Standard:
Inner ``A'': 0.7 - 0.9 mm (0.028 - 0.035 in)
Outer ``B'': 0.6 - 1.1 mm (0.024 - 0.043 in)
Wear limit:
0.2 mm (0.008 in)
lIf dimension ``A'' or ``B'' is smaller than the wear limit,
replace outer baulk ring, inner baulk ring and synchro-
nizer cone as a set.
BEARINGS
lMake sure all bearings roll freely and are free from noise,
cracks, pitting or wear.
