- Clean all the synchronizer parts in a suitable solvent. Air dry
all the synchronizer parts.
- Inspect the synchronizer parts for the following conditions:
• | Chamfer for excessive wear |
• | Free movement of the clutching sleeves on their hubs |
• | Worn or damaged clutch teeth |
- 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:
4.1. | Assemble the correct blocking ring with the correct speed gear. |
4.2. | The blocking ring must be fully seated on the gear. |
4.3. | Use a feeler gauge to measure the forward gear gap. |
4.4. | Use a feeler gauge to measure the reverse gear gap. |
Measure the gap without the wave washer in between the blocking ring
and the reverse gear.
The nominal gap is 1.27-2.032 mm (0.050-0.080 in)
for the 1st and 2nd gear.
The nominal gap is 0.79-1.57 mm (0.031-0.062 in)
for the 3rd, 4th, 5th and 6th gear.
Replace friction cone and blocking ring when the gap is significantly
less than specified.
