Timing Chain Removal

ALLDATA Editor Note: Volkswagen does not provide a step by step timing chain removal procedure. The procedure depicted below is for the AFP engine, the AES is similar.

Preliminary Work
- Remove engine from vehicle
Engine is removed downward with transmission

- Remove drive plate

Removal

Alldata Editor Note: This procedure has been enhanced for improved usability.








- Set crankshaft to TDC Cyl. 1 marks -arrow- by turning crankshaft via vibration damper bolt (in direction of engine rotation).
- Remove cylinder head cover.





NOTE: Take note of timing grooves used for timing the engine.





- Insert Camshaft Guide 3268 Tool into both shaft slots.





- Remove upper tensioner bolt.





- Remove bolts - arrows - from upper timing chain case cover.

- Remove upper timing chain case cover.

CAUTION: Do not damage Cylinder Head Gasket, when removing timing covers.






1) Timing Chain Upper Guard Rail.
2) Camshaft Sprockets
3) Shutter Wheel
4) Timing Chain Upper Tensioner Rail.






NOTE:
If TDC Cyl. 1 position is correct, it will be possible to see a slot - arrow - on the sprockets of the intermediate shaft.
If the groove cannot be seen:
- Turn crankshaft one turn further in direction of rotation of engine.





- Remove bolts - arrows - from lower timing chain case.

- Remove lower timing chain case cover.

CAUTION: Do not damage Cylinder Head Gasket, when removing timing covers.





Marking roller chains
