Replacing the timing belt (VW Golf 1)

In this case, you should first read the instructions provided under the heading "Timing Belt Adjustment".

Two sets of feeler gauges, VW 2065 or 2065 A adjustment ruler and 2064 mandrel are used. The mandrel and ruler can be made according to the attached drawings (see picture).

This is what the fuel pump timing belt pulley mandrel looks like. It's a simple round piece; the handle at the rear end is optional. The length is also unimportant. The decisive factor: the mandrel must be placed between the hole in the fuel pump pulley and the hole in the pump bracket. It is important that the mandrel maintains a certain diameter. It must be exactly 15.45 mm.

A setting ruler can be made from these dimensions. The exact length is not so important. The adjustment ruler should be at least as long as the side of the cylinder head indicated.

Remove the valve cover and timing belt cover.

Set the first cylinder to top dead center (TDC).

Insert the alignment ruler into the transverse slot of the shaft at the end of the camshaft facing left in the direction of travel.

Now insert one sheet of feeler gauge of the same thickness between the cylinder head and the installation ruler at both ends of the ruler; thickness must be set! See the picture. This eliminates the play between the installation ruler and the cylinder head - the camshaft can no longer be rotated.

Lock the fuel pump. To do this, insert the 2064 mandrel into the small hole in the pump wheel (the hole is directed to the right) and into the hole located behind the pump holder.

Loosen the timing belt tension roller nut.


Turn the tension roller to the left; this loosens the tension on the timing belt.

Remove the V-belt.

Remove the V-belt pulley and cover.

Remove the timing belt

Before installing a new timing belt, loosen the camshaft timing belt pulley retaining screw by 1/2 turn.

Disconnect the camshaft pulley from the camshaft cone using a light blow from a rubber hammer.

Now the pulley can turn on the camshaft.

Check again: is the crankshaft at top dead center (TDC)?; whether the camshaft and fuel pump are fixed correctly.

Install the timing belt and tighten it (see previous section) Do not rotate the crankshaft.

Tighten the timing belt pulley mounting screw to a tightening torque of 45 Nm.

Tighten the timing belt again. Now you can turn the crankshaft.
