Gear Components

GEAR AND SHAFT







- 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 spread spring for deformation.




- Measure clearance between baulk ring and gear.

If the clearance is smaller than the wear limit, replace baulk ring.







- Measure wear of 2nd baulk ring.
a. Place baulk rings in position on synchronizer cone.
b. While holding baulk rings against synchronizer cone as far as it will go measure dimensions "A" and "B".
Standard:
Inner-A 0.7 - 0.9 mm (0.028 - 0.035 in)
Outer-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.

BEARINGS




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