Synchronizer Ring: Testing and Inspection

1. Inspect the synchronizer ring teeth for damage, wear, and cracks.
2. Inspect the tapered surface for wear and cracks.
3. Set the synchronizer ring squarely in the gear.





4. Measure the clearance between the synchronizer ring and the flank surface of the gear all around the circumference. Standard clearance is 1.50 mm (0.059 inch) and the minimum is 0.80 mm (0.031 inch).
