DISASSEMBLY AND ASSEMBLY OF SUBASSEMBLIES
Synchronizers
Disassembly and Assembly
NOTE:
This procedure applies to all synchronizer assemblies.
1. NOTE: Synchronizer components are not interchangeable. During disassembly, mark each
individual synchronizer for assembly. Synchronizer hubs and sleeves are a selected assembly
and should be kept together as originally assembled. Blocking rings are not interchangeable, do
not mix.
Scribe an alignment mark on the sliding sleeve and the hub for assembly reference.
2. Using a screwdriver, remove the spring. Turn the synchronizer over and remove the second spring. Remove the sliding sleeve and the synchronizer struts from the hub.
3. CAUTION: Match the alignment marks made during disassembly. The sleeve and
the hub have an extremely close fit. Hold the sleeve and hub square to prevent jamming.
Do not force the sleeve onto the hub.
Assemble the synchronizer as follows:
zPosition the synchronizer sleeve on the hub. Make sure to align key openings in the hub
with the synchronizer sleeve.
z Install the keys with the slots facing the hub.
z Install the spring. Locate the tang to one of the key slots and position into place. Install
the second spring. Locate the spring tang on the same key but position in the opposite
direction.
