Balance shaft tube - mounting position

The balance shaft tube journal must be fixed in the "arrow" groove.

Support pin - mounting position

Replace and lubricate the O-ring "1". The mounting pin "arrow" of the support pin must enter the hole in the cylinder block. Lubricate the support pin.

Star - tightening sequence

Caution: The intermediate gear must be replaced. Otherwise, the lateral clearance is not created and, as a result, the engine is damaged. The new intermediate shaft sprocket has a smooth varnish coating, which wears off after a short time and thus automatically creates a lateral clearance.
