Tools required:
A flat bar, VW tool 2065A is used to secure the camshaft in position.
A pin, VW tool 2064 is used to fix the pump position while the timing belt is removed.
IMP NOTE: The camshaft and pump work against spring pressure and will move out of position when the timing belt is removed. It is not difficult to find substitutes but do not remove the timing belt without these tools.

The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head.Make sure you dont clean or rub off the alignment marks.
- With the engine at TDC, insert the bar into the slot at the back of the camshaft. The bar rests on the cylinder head to will hold the camshaft in position.
- Insert the pin into the injection pump drive sprocket to hold the pump in position.
- Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt. Slide the timing belt from the sprockets.
