Chain Sprocket Tightening Sequence

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 antifriction coating that wears off after a short period of use, which automatically adjusts the backlash.

- 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 degree using a rigid wrench.
