Gear Components: Inspection: Synchronizers
WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
- Check spline portion of coupling sleeves, hubs, and gears for wear or cracks.
- Check baulk rings for cracks or deformation.
- Check shifting inserts for wear or deformation.
- Check insert springs for deformation.
- Measure wear of main drive, 1st and OD baulk rings.
Clearance between baulk ring and gear:
Refer to SERVICE DATA AND SPECIFICATION (SDS) .
- If the clearance is smaller than the wear limit, replace baulk ring.
- Measure wear of 2nd and 3rd baulk rings.
- Place baulk rings in position on synchronizer cone.
- While holding baulk rings against synchronizer cone as far as it will go, measure dimensions "A" and "B".
Standard:
A 0.7 - 0.9 mm (0.028 - 0.035 in)
B 0.6 - 1.1 mm (0.024 - 0.043 in)
Wear limit:
0.2 mm (0.008 in)
- If dimension "A" or "B" is smaller than the wear limit, replace outer baulk ring, inner baulk ring and synchronizer cone as a set.
- Measure wear of reverse baulk ring.
- Place baulk ring in position on reverse cone.
- While holding baulk ring against reverse cone as far as it will go, measure dimension "A" with dial indicator.
Dimension "A":
Standard -0.45 to 1.05 mm (-0.0177 to 0.0413 in)
Wear limit 0.7 mm (0.028 in)
- If dimension "A" is larger than the wear limit, replace baulk ring.
