Disassembly And Assembly Of Subassemblies: Synchronizers: Disassembly
WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
This procedure applies to all synchronizer assemblies.
- Scribe an alignment mark on the sliding sleeve and the hub for assembly reference.
- Using a screwdriver, remove the spring. Turn the synchronizer over and remove the 2nd spring. Remove the sliding sleeve and the synchronizer struts from the hub.
- Inspect the synchronizer components.
- Check for worn, nicked or broken teeth. Install a new synchronizer as necessary.
- Check keys for wear or distortion. Install a new synchronizer as necessary.
- Check springs for distortion. Install a new synchronizer as necessary.
- Inspect the synchronizer blocking rings.
- Check for wear or damage. Install new synchronizer blocking rings as necessary.
- Check the clearance between the synchronizer blocking ring and the gear.
- Position the blocking ring onto the gear. Make sure the correct blocking ring is measured with the correct gear and that the blocking ring is fully seated on the gear.
- Insert a feeler gauge and measure the clearance, while applying pressure and rotating the blocking ring. The measurement should be the same around the entire circumference. If the clearance is less than 0.38 mm (0.015 in), install new blocking rings.
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.
