¹⁾      Bolts are to be inserted with locking compound. Subsequent tightening is not permitted.

²⁾     Must be tightened in three stages - 25 Nm + 60° + 60° +60°.

³⁾     Insert lower bolts with Locking Compound 15 05 101 (9 293 722).

⁴⁾     Then turn a further 50° to 90°.

⁵⁾     Then turn a further +60° to 80°.

 

Note:

For angle tightening, tighten bolts to angle given and then tighten further by angle given.

Use bolts only once.
