CAUTION!
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 the bolt as follows

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

- Turn the chain sprocket.

The chain sprocket may not have any play; if so, loosen and tighten again.

- Tighten to 30 Nm using a torque wrench.

- Tighten further 90° using a rigid wrench.
