Synchronizer Ring: Testing and Inspection
INSPECTION
1. Inspect gear teeth on synchronizer ring. If evidence of chipping or excessively worn teeth are present, replace component.
Checking Synchronizer Ring
2. Check synchronizer ring for wear by assembling synchronizer ring to gear cone.
3. Measure clearance between side faces of synchronizer ring and gear using a suitable feeler gauge. If clearance is less than 0.031 inch, replace
synchronizer ring or gear, 1st/2nd, 3rd/4th, and 5th/reverse synchronizer to gear clearance specifications are the same.
4. Check for proper contact between inner surface of synchronizer ring and cone surface of gear by applying a thin coat of Prussian blue or
equivalent to surface of cone, then fitting it into ring. If contact pattern is poor, correct by applying compound and lapping surfaces together.
5. Ensure clutch sleeve slides easily onto clutch hub.
6. Check synchronizer inserts (keys), inner surface of clutch sleeve, then the insert groove on clutch hub from wear.
7. Check synchronizer insert spring for tension.
