Intermediate Shaft Sprocket Tightening Sequence
Always replace the intermediate shaft sprocket. Otherwise the backlash will not adjust itself and it could result in engine damage.
The new intermediate shaft 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.
- Rotate the intermediate shaft sprocket.
The intermediate shaft 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.
