Synchronizer

Note:

- Check spline portion of coupling sleeves, hubs and gears for wear or cracks.
- Check baulk rings for cracks or deformation.
- Check insert springs for deformation.





Note: Measure clearance between baulk ring and gear (1st).Clearance between baulk ring and gear:

Standard: 1.0 - 1.35 mm (0.0394 - 0.0531 in)
Wear limit: 0.7 mm (0.028 in)





Note: Measure wear of 2nd baulk rings.
a. Place baulk rings in position on synchronizer cone.
b. While holding baulk ring against synchronizer cone as far as it will go, measure dimensions "A" and "B".

Standard:
A 0.6 - 0.8 mm (0.024 - 0.031 in)
B 0.6 - 1.1 mm (0.024 - 0.043 in)

Wear Limit: 0.2 mm (0.008 in)

c. If dimension "A" or "B" is smaller than the wear limit, replace baulk ring.
