Synchronizer Assemblies

Description

Synchronizers and synchronizer rings together are
responsible for engaging the transmission gears.

There are three synchronizer assemblies in this
transmission model:

•

1st/2nd speed synchronizer

•

3rd/4th speed synchronizer

•

5th/reverse speed synchronizer

NOTE: When repairing synchronizer
assemblies, do not replace a single part only.
Allways replace the assembly. If would be
necessary to replace one synchronizer ring,
allways replace the transmission
synchronizer ring set.

1. Synchronizer hub

2. Key (3x)

3. Spring (3x)

4. Synchronizer sleeve

5. Synchronizer ring with EFM II coating

6. Synchronizer ring without EFM II coating

NOTE: The EFM II is a special coating used
in some synchronizer rings to increase its
lifetime.

Disassembly

1. With the hands, remove the synchronizer

sleeve from the hub.
