Volkswagen Golf/Jetta 2 manual

Distributor - removal and refitting
Ignition system - transistorised type / Distributor - removal and refitting


Note: On 1.05 and 1.3 litre engines equipped with hydraulic tappets, distributor removal and refitting is basically the same as described in Part A of this Chapter for the contact breaker type
TCI-H system
Removal
1 Pull the high tension connection from the centre of the ignition coil and remove the caps from the spark plugs.

2 Disconnect the screen (suppression) earth lead (see illustration) and withdraw the screen, then release the clips and lift off the distributor cap. Do not allow the cap retaining clips to fall inwards or the rotor or trigger wheel may be damaged.

3 Disconnect the control unit lead multi-plug by releasing the wire retaining clip.

4 Unscrew and remove the TDC sensor or blanking plug from the top of the gearbox (see illustration) then turn the engine over until the TDC УOФ mark is aligned with the timing pointer (see illustration). If not already marked, scribe an alignment mark on the distributor body in line with the tip of the rotor arm (see illustration). Also mark the distributor body and cylinder block in relation to each other.

5 Pull the vacuum pipe(s) from the vacuum control unit, marking the position of the pipes if there is more than one.

6 Remove the bolt and washer from the distributor clamp plate and remove the clamp plate. Withdraw the distributor and remove the gasket, which must be renewed (see illustrations).

Refitting
7 Refitting is a reversal of the removal procedure. When the distributor is in position, check that the rotor arm points to the No. 1 cylinder mark before tightening the clamp plate bolt.

8 On completion, check and if necessary adjust the ignition timing.

10 Disconnect the wiring harness plug from the side of the distributor body.

11 Unscrew the clamp plate screw, remove the clamp plate and withdraw the distributor.

Refitting
12 Before fitting the distributor, set No. 1 piston to TDC. When correctly set, the flywheel mark or the crankshaft pulley vibration damper mark should align with the matching mark on the casing or belt cover.

The mark on the camshaft sprocket must align with the joint of the camshaft cover.

13 Using a screwdriver, turn the slot in the end of the oil pump driveshaft so that it is parallel with the crankshaft centre-line.

14 Set the rotor arm so that it points to the mark (No. 1) on the distributor body rim.

15 Install the distributor so that the wiring harness LT plug socket is in the position shown (see illustration). Check and if necessary adjust the ignition timing.
