Synchro Ring, Gear
Inspection
1. Inspect the synchro ring and gear.
A: Inspect the inside of the synchro ring for wear.
B: Inspect the synchro sleeve teeth and matching
teeth on the synchro ring for wear (rounded off).
r- /-\
oioi *-o*
C: Inspect the synchro sleeve teeth and matching
teeth on the gear for wear (rounded off).
,

UtJGOOO WORN
D: Inspect the gear hub thrust surface for wear.
E: Inspect the cone surface for wear and roughness.
Fr Inspect the teeth on all gears for uneven wear,
scoring, galling, and cracks.
2. Coat the cone surface of the gear with oil. and place
the synchro ring on the matching gear. Rotate the
synchro ring. making sure that it does not slip.
Measure the clearance between the synchro ring
and gear all the way around.
NOTE: Hold the synchro ring against the gear evenly
while measuring the clearance.
Synchro Ring-to-Gear Clearance
Standard: 0.73 - 1.18 mm {0.029 - 0.046 in}
Service Limit 0.4 mm {0.02 in)
lf the clearance is less than the service limit, replace
the synchro ring and synchro cone.
