MECHANISM
1. Install striking lever & rod, striking interlock assembly and con-
trol bracket on clutch housing exactly.
IWhen installing control bracket on clutch housing, assure
protrusion beneath bracket is correctly seated.
2. Measure maximum height ªHº while shifting from neutral to
reverse position.
Maximum height ªHº:
67.16 - 67.64 mm (2.6441 - 2.6630 in)
3. Remove control bracket from clutch housing.
4. Measure clearance ªCº between reverse brake cam and strik-
ing lever at reverse position.
Clearance ªCº:
0.05 - 0.125 mm (0.0020 - 0.0044 in)
5. If height ªHº and clearance ªCº are not within specifications,
replace control bracket, striking lever and striking interlock
assembly as a set.

c. Measure turning torque of final drive assembly.
Turning torque of final drive assembly
(New bearing):
2.9 - 6.9 N´m (30 - 70 kg-cm, 26 - 61 in-lb)
IWhen old bearing is used again, turning torque will be
slightly less than the above.
IMake sure torque is close to the specified range.
IChanges in turning torque of final drive assembly per
revolution should be within 1.0 N´m (10 kg-cm, 8.7 in-lb)
without binding.
