Disassembly And Assembly Of Subassemblies: Synchronizers: Disassembly

NOTE: This procedure applies to all synchronizer assemblies (7124). The synchronizers are slightly different in design. Notation is made where procedural differences occur.

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

NOTE: Only the synchronizer hub insert springs (7109) and the synchronizer hub inserts (7A044) are available separately.

Remove the synchronizer hub inserts and the hub insert springs.
The first/second speed synchronizer sliding sleeve, the hub, and the output shaft are an assembly. Do not attempt to separate the hub from the output shaft. Discard the entire assembly if wear or damage to the synchronizer or output shaft is evident.
