Chain Sprocket Bolt 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 the bolt as follows:

- Tighten the bolt 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 the bolt to 30 Nm using a torque wrench.

- Tighten the bolt an additional 90° (1/4) turn using a ratchet.
