WARNING:

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 to 10 Nm.

-- Turn the chain sprocket.

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

-- Tighten the bolt to 30 Nm.

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