Cleaning & Inspection: Synchronizers

If teeth on synchronizer ring are chipped, broken or worn, replace synchronizer ring. Note that 3rd gear synchronizer is different from others. To check for wear, mount synchronizer to mating gear and measure clearance between gear and synchronizer side faces using a feeler gauge. If clearance is less than 0.031" (0.80 mm), replace synchronizer ring or mating gear.

Check contact surfaces of shift fork and clutch hub sleeve for wear or damage. Using feeler gauge, check shift fork-to-clutch hub sleeve clearance. Clearance should not exceed 0.031" (0.80 mm). Check operation of clutch hub sleeve installed on hub. Position clutch hub and sleeve horizontally. Lift hub approximately 3/4 of the way off sleeve and release. If hub does not return into sleeve, service as necessary.
