📋 Procedure

1. Remove upper timing chain cover .
2. Remove lower timing chain cover .
3. Remove camshaft timing chain and drive chain for balance shaft .
4. Remove toothed belt for coolant pump .
5. Remove intermediate gear (1).

6. Unscrew bolt (2) for inlet camshaft balance shaft and pull out balance shaft.
7. Insert shell half T10394/1 from puller T10394 and turns upwards in direction of arrow.
8. Insert puller T10394 and push locking collar in (direction of arrow).
9. Screw puller T10055 into puller T10394 and force out balance shaft in (direction of arrow). [Note: Due to the small amount of play between the balance shaft and cylinder block, the balance shaft may need to be installed chilled. Check whether the balance shaft can be fitted into the cylinder block without exerting force. If this is not the case, the balance shaft must be chilled before installing.]
10. Place new balance shaft in freezer compartment for 30 minutes or spray with commercially available cooling spray.
11. Lubricate balance shaft bearing with engine oil.
12. Install new balance shaft for inlet camshaft and tighten bolt (2).
13. Renew O-ring (1) and lubricate with engine oil.
14. Lubricate bearing mounting with engine oil and insert (arrow); bearing mounting must engage in bore in cylinder block.
15. ⚠ The intermediate shaft sprocket must be renewed. Otherwise no tooth backlash is set - engine damage. The new intermediate shaft sprocket is coated with a solid film lubricant that wears off after a short period and thus automatically sets the tooth backlash. — Mark faces of gear teeth of idler gear with paint (arrows).
16. Insert intermediate gear; marking on balance shaft must be positioned between markings on faces of gear teeth.
17. Tighten bolt for chain sprocket (1): tightening sequence .
18. Check markings on intermediate shaft sprocket and balance shaft (arrow). [Note: Due to the ratio, the markings align only after every 7th turn.]
19. Install drive chain for balance shaft and camshaft timing chain .
20. Renew oil seal for coolant pump drive .
