Tip

The new intermediate shaft sprocket has an anti-friction coating that wears off after a short period of use and thus automatically adjusts the backlash.

-- Insert the intermediate shaft sprocket.

Requirement

• The marking on the intake side balance shaft must be between the markings on the tooth flanks.

-- Pay attention that the intermediate shaft sprocket and the balance shaft face each other as shown.
