SYNCHROSLEEVE
When assembling the synchro sleeve and synchro
hub, be sure to match the three sets of longer teeth
(120 degrees apart) on the synchro sleeve with the
three sets of deeper grooves in the synchro Hub

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.
