Synchronizer Keys & Springs

NOTE: Synchronizer hubs and sliding sleeves are a selected assembly and should be kept together as originally assembled, but the keys and springs may be replaced if worn or broken.


1. Mark relation of hub and sleeve for reassembly reference.

2. Push hub from sliding sleeve, allowing keys to fall free and simplifying spring removal.

3. Place keys in position and hold in place while sliding sleeve onto hub, aligning reference marks.

4. Place the two springs in position on either side of hub so that all three keys are engaged by both springs.
