NOTE:
RISK OF DAMAGE
Damage to the engine.
If the engine is manually rotated in the wrong direction of rotation, the engine can be damaged.
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 leftward at an angle.
- Ensure that the flat sections (1) at the intake and exhaust camshaft 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 .
