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 vibration damper in engine rotation direction to TDC. Do not turn 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 inspection mirror, if necessary).
• The marks - 1 - on the camshafts must point upward.
- Measure the distance from the outer edge - A - to the mark - B - on the intake camshaft.
• Specified value: 61 to 64 mm.
- Once the specified value is reached, measure the distance between the mark on the intake camshaft - B - and 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.
