Tightening Specifications

CAUTION:

Always replace the intermediate sprocket. Otherwise the backlash will not adjust itself and it could result in engine damage.

The new intermediate sprocket has an anti-friction coating that wears off after a short period of use, which automatically adjusts the backlash.

-- Tighten with a new bolt as follows:

-- Partially tighten to 10 Nm using a torque wrench.

-- Turn the intermediate sprocket.

The intermediate sprocket must not have any play. Loosen and tighten it again if necessary.

-- Tighten to 25 Nm using a torque wrench.

-- Turn another 90° using a rigid wrench.
