Camshaft Timing Chain, Removing From Camshafts: Removing: Notes

WARNING: This page is about a different car, the 2018 Audi A6 Quattro, 2017 Audi A6 Quattro, and 2016 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The camshaft timing chains stay on the engine in the following description.

Even when only one cylinder head is worked on, the work procedure must nevertheless be performed on both cylinder banks.

-- Remove the left and right timing chain guards. Refer to LEFT TIMING CHAIN COVER, REMOVING AND INSTALLING .

-- Remove the left and right cylinder head cover. Refer to CYLINDER HEAD COVER, REMOVING AND INSTALLING .

-- Remove the noise insulations. Refer to NOISE INSULATION .

-- Insert the :T40058 guide pins as follows:

The large diameter -arrow 1- faces the engine.
The small diameter -arrow 2- faces the adapter.

-- Rotate the crankshaft in the direction of engine rotation -arrow- to "Top Dead Center (TDC)" using the :T40058 and wrench.

NOTE:

Rotate the engine until the small notch -1- on the vibration damper aligns at the left of the housing separation point -2- between the cylinder block and the guide frame. This makes it easier to install the :T40069 later.

The marking on the vibration damper is only there to help. The exact "TDC" location is only reached by installing the :T40069 .

The threaded holes -arrows- in all the camshafts must face upward.

NOTE:

When the camshafts are not positioned as stated, turn the camshaft one turn farther and back to "TDC".
