Balance shaft tube - mounting position
The stud of the balance shaft tube must engage in the groove -arrow-.
Support pin - mounting position
Replace and lubricate O-ring -1-. The locating pin -arrow- of the support pin must engage in the bore of the cylinder block. Lubricate the pivot pin.
Asterisk - tightening sequence
Caution: The intermediate gear must be replaced. Otherwise, side clearance is not created and, as a result, engine damage is not created. The new layshaft sprocket has a smooth lacquer coating that wears off after a short time and thus automatically creates side play.
Tighten the bolt in the following order.
- 1. Pre-tighten with a torque wrench to 10 Nm.
- 2. Rotate the sprocket. The sprocket must not have any play, otherwise loosen and re-tighten.
- 3. Tighten with a torque wrench to 30 Nm.
- 4. Tighten 90°with a hard wrench.
