■ Installation

1. Concentricity of the inner and outer races is maintained by the plain bearing located between the outer race and the shaft.
Radial loads which work on the outer race are also supported by this plain bearing. The shaft must therefore be extended
through the clutch outer race end.
2. Recommended shaft tolerances are as follows.
PB3, PB5, PB6, PB8
PB10, PB12, PB14
3. The bore of the driven member, such as the sprocket on the clutch outer race, should meet H6 or H7 tolerance of the JIS
standard
