Damage to the engine .
If the engine is manually rotated in the wrong direction of rotation, the engine can be damaged .
- Only rotate the engine manually in the correct direction of rotation: a) clockwise when looking at the damper, or b) counterclockwise when looking at the chain drive. b) applies only if the timing chain is installed in the rear.
- With the special tool, turn the engine 0 493 380 (11 6 480) to the TDC firing position of cylinder 1 .
- Make sure the marks (1) on the intake camshaft (E) and the exhaust camshaft (A) are legible from above.
- Make sure the cam (1) on the exhaust camshaft on cylinder 1
is pointing slightly to the inside right at an angle.
- Make sure the cam (1) on the intake camshaft on cylinder 1
is pointing leftwards at an angle.
- Make sure that the flat sections (1) on the intake and exhaust camshafts point upwards.
- Position the basic carrier (1) from the set of special tools 2 456 372 on the cylinder head.
- Tighten screws (2) from the set of special tools 2 456 372 .
