Synchronizers Disassemble: Notes

1st/2nd, 3rd/4th, 5th/6th Synchronizers 

Important:  Synchronizer components are not interchangeable. Keep all the synchronizer components separate. The synchronizer hubs and the sliding sleeves are a selected assembly. Keep the hubs and the sliding sleeves together as originally assembled.

1. Scribe a mark on the synchronizer hub and on the sleeve. This will help you to reinstall the parts in the same position.
