SYNCHRONIZER RING INSPECTION
(a) Turn the ring and push it in to check the braking action.
(b) Measure the clearance between the synchronizer ring back and the gear spline end.
Standard clearance:
0.8 - 1.6 mm (0.031 - 0.063 in.)
Minimum clearance:
0.6 mm (0.024 in.)
If the clearance is less than the limit, replace the synchronizer ring.
