Intermediate 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.
- Turn the sprocket.
The sprocket may not have any play; if so, loosen and retighten again.
- Tighten the bolt to 30 Nm.
- Tighten the bolt an additional 90° (1/4) turn.
