Cylinder Head Assembly: Adjustments

Valve Timing, Checking

- Remove the upper timing chain cover. Refer to => [ Upper Timing Chain Cover ] Upper Timing Chain Cover.

- Remove the noise insulation..

- Disconnect the right charge air hose at the coupling.

- Rotate the vibration damper, from underneath, in engine rotation direction to Top Dead Center (TDC) - arrow -.






• Use a ratchet with a 24 mm socket to rotate the vibration damper. Always turn the vibration damper in engine rotation direction to TDC. Do not rotate the vibration damper backward to get to TDC!

• The notch on the vibration damper must line up with the arrow mark on the lower timing chain cover (use a mirror, if necessary).

• The marks - 1 - on the camshafts must point upward.

- Measure the distance from the outer edge of the cylinder head cover - A - to the mark on the intake camshaft - B -.






• Specified value: 61 to 64 mm.

- Once the specified value is reached, measure the distance between the mark on the intake camshaft - B - to the mark on the exhaust camshaft - C -.






• Specified value: 124 to 126 mm

• If one tooth has an offset, there will be a deviation of approximately 6 mm from the specified value. Install the timing chain once again if there is an offset.
