Synchronizers

Disassembly

Note: This procedure applies to all synchronizer assemblies. The synchronizers are slightly different in design. Notation is made where procedural differences occur.

1. On the first/second synchronizer and the third/fourth synchronizer, scribe an alignment mark on the sliding sleeve and the hub for assembly reference.

2. Note: Only the synchronizer blocking spring and the synchronizer struts are available separately.





Remove the synchronizer struts and the blocking springs.
3. On the first/second synchronizer and the third/fourth synchronizer, remove the sliding sleeve.

Assembly

1. Note: Both synchronizer blocking springs engage the same synchronizer strut but rotate in the opposite direction.





Install the synchronizer struts and the blocking springs. Verify that the spring tabs are positioned over the struts.

2. 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.

On the first/second synchronizer and the third/fourth synchronizer, install the sliding sleeve.
