GEAR COMPONENTS

Inspection


GEARS AND SHAFTS






- Check shafts for cracks, wear or bending.





- Check gears for excessive wear, chips or cracks.

SYNCHRONIZERS






- 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. Baulk Ring Clearance.
- If the clearance is smaller than the wear limit, replace baulk ring.





- Measure wear of 2nd and 3rd double baulk rings using Tool.

Tool number:ST-30031000 (J-22912-01)

- Place baulk rings in position on synchronizer cone.
- While holding baulk rings against synchronizer cone as far as it will go, measure the dimensions (A) and (B).

Standard
Dimension (A): 0.7 - 0.9 mm (0.028 - 0.035 in)
Dimension (B): 0.6 - 1.1 mm (0.024 - 0.043 in)
Wear limit: 0.2 mm (0.008 in)





- If the 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 the dimension (A) with dial indicator.

Standard
Dimension (A): 0.35 - 0.95 mm (0.0138 -0.0374 in)
Wear limit: 1.1 mm (0.043 in)

- If the dimension (A) is larger than the wear limit, replace baulk ring.

BEARINGS






- Make sure bearings roll freely and are free from noise, crack, pitting or wear.
