Camshaft Timing Chain, Removing And Installing: Removing

-- Remove the upper timing chain cover. Refer to UPPER TIMING CHAIN COVER, REMOVING AND INSTALLING .

TIP:

The control valves have left-hand thread.

-- Remove the left and right control valves using the Assembly Tool -1- in the direction of -arrow-.

Depending on the version of the control valve use one of the listed tools:

• : T10352 
• : T10352/1 
• : T10352/2 
• : T10352/3 
• : T10352/4 

-- Remove the bolts -arrows- and bearing bracket.

• Carefully remove the bearing bracket without tilting it.

-- Remove the bearing mount.

-- Turn the vibration damper in the "TDC" position.

TIP:

Depending on the version the mark -arrow- is not present. It is enough that the marks -1- point upward.

• The notch on the vibration damper and the marking on the lower cover for timing chain must be opposite one another -arrow-.
• The markings -1- on the camshaft chain sprockets must point upward.

TIP:

The combination of the : T40263  , : T40314  and 24 mm socket are better suited than the : T10355A  for positioning the vibration damper.

-- Remove the lower timing chain cover. Refer to LOWER TIMING CHAIN COVER, REPLACING .

-- Check the "TDC point" again.

-- Press the oil pump chain tensioner bracket in direction of -arrow- and lock with : T40011  .
