Inspect synchronizer ring
Apply pressure to the gear and synchronizer ring with the hands. While maintaining this pressure, use a thickness gauge to measure the clearance around the entire circumference.
HINT:
As the inner surface circumference of the synchronizer ring wears, the ring tends to cave in towards the gears thereby closing the clearance distance between the gear and synchronizer ring.
 
3.
Inspect synchronizer ring operation
Apply pressure to the synchronizer ring to install it with the cone of gear by hand. Then make sure that the synchronizer ring does not slip when applying force in the turning direction.
