Synchronizers Cleaning and Inspection
WARNING: This page is about a different variant/trim than selected.
- Clean all the synchronizer parts in a suitable solvent. Air dry all the synchronizer parts.
- Inspect the synchronizer parts for the following conditions:
- Burrs
- Cracks
- Hicks
- Chamfer for excessive wear
- Free movement of the clutching sleeves on their hubs
- Worn or damaged clutch teeth
- Distorted springs
- Replace synchronizer parts that are worn or damaged.
Replace a burred or nicked part that cannot be reconditioned by hand. Use a soft stone or a crocus cloth.
- Measure the gap between the vertical faces of the blocking ring teeth and the speed gear as follows:
- Assemble the correct blocking ring with the correct speed gear.
- The blocking ring must be fully seated on the gear.
- Use a feeler gauge to measure the forward gear gap.
- Use a feeler gauge to measure the reverse gear gap.
The nominal gap is 1.27-2.16 mm (0.050-0.085 in) for the 1st and 2nd gear.
The nominal gap is 1.27-2.03 mm (0.050-0.080 in) for the 3rd, 4th, 5th and 6th gear.
Replace the friction cones and blocker rings when the gap is less than specified.
NOTE:
Measure the gap without the wave washer in between the blocking ring and the reverse gear.
