Check toothed belt tension.
Rotate the crankshaft until the TDC mark on the flywheel matches the pointer in the gearbox housing. At the same time, the camshaft lobes of the 1st cylinder must point up to the left and up to the right. In this position, you can insert the locking ruler 20665A into the camshaft spline.
Lock the camshaft with a ruler. Ruler (VW2065A) has a bend so that the camshaft does not rotate. They need to get into the camshaft slot.
If the ruler is not inserted, turn the crankshaft so. so that the line can be inserted. Center the ruler as follows.
Rotate the camshaft. so that the end of the ruler rests on the cylinder head. Measure the gap at the other end of the ruler with a feeler gauge.
Insert a half thickness feeler gauge between the ruler and the cylinder head. Turn the camshaft so that the ruler is pressed against the dipstick. Insert a second probe of the same size at the other end of the ruler.
Drift 2064 should now fit into the hole in the fuel pump wheel and pump holder. If the mandrel cannot be inserted into the hole, the motor control must be re-adjusted.
To do this, turn the crankshaft so that the TDC marks of the piston of the 1st cylinder coincide with the pointer on the gearbox housing and at the same time the camshaft cams for the 1st cylinder are turned upwards to the left and upwards to the right.
Lock the camshaft with a ruler.
Loosen the camshaft wheel mounting bolt ½ turn. Using a hammer and a ∅ 6 mm drift, knock the camshaft wheel off the cone with one blow through the hole in the toothed belt guard.
Turn the fuel pump wheel so that the markings on the injection pump wheel and bracket -black arrow- coincide.
Lock the pump impeller with a suitable pin.
Attention: If required for correct installation, remove toothed belt and tension after installation.
Tighten the camshaft wheel bolt to 45 Nm. Remove the adjusting ruler and rod.
Check the moment of the start of injection pump supply.
