Intermediate Sprocket Tightening Sequence
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:
- 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.
- Tighten further 90° using a rigid wrench.
