Gear Components
1. Before removing gears and shafts, measure each gear end play.
Gear End play mm (in)
1st main gear 0.23 - 0.33 (0.0091 - 0.0130)
2nd main gear 0.23 - 0.33 (0.0091 - 0.0130)
3rd main gear 0.23 - 0.33 (0.0091 - 0.0130)
OD counter gear 0.23 - 0.33 (0.0091 - 0.0130)
Reverse main gear 0.33 - 0.43 (0.0130 - 0.0169)
IIf not within specification, disassemble and check contact sur-
face of gear to hub, washer, bushing, needle bearing and shaft.

Shift Control Components
ICheck contact surface and sliding surface for wear, scratches,
projections or other damage.
Gear Components
GEARS AND SHAFTS
ICheck shafts for cracks, wear or bending.
I Check gears for excessive wear, chips or cracks.
SYNCHRONIZERS
ICheck spline portion of coupling sleeves, hubs, and gears for
wear or cracks.
I Check baulk rings for cracks or deformation.
I Check shifting inserts for wear or deformation.
I Check insert springs for deformation.
Clearance between baulk ring and gear
Unit: mm (in)
Standard Wear limit
1st & 2nd 1.05 - 1.3 (0.0413 - 0.0512) 0.7 (0.028)
3rd & main drive 1.05 - 1.3 (0.0413 - 0.0512) 0.7 (0.028)
OD 1.05 - 1.3 (0.0413 - 0.0512) 0.7 (0.028)
If the clearance is smaller than the wear limit, replace baulk ring.
