ADJUSTMENT OF INPUT SHAFT BRAKING
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.
