Distributor — removal and installation (Opel Ascona C)

Engine 1.3

1. Remove the spark plugs.

2. Loosen the screws securing the distributor cap and remove it.

3. Put the car in gear, release the handbrake and push the car forward until your finger is placed on the spark plug hole of cylinder No. 1 (the cylinder closest to the crankshaft pulley), will not feel pressure. Continue to move the machine forward until the mark on the crankshaft pulley aligns with the pointer (see photo). (On models with an automatic transmission, the engine should be turned using a wrench placed on the crankshaft pulley bolt). If you temporarily replace the distributor cap, the rotor should be positioned opposite the electrode corresponding to the spark plug wire No. 1.



4. Disconnect the distributor wiring at the ignition coil (see photo) and disconnect the vacuum tube of the vacuum regulator from the distributor.





5. Unscrew the distributor clamp nut (or bolt), remove the clamp plate and remove the distributor from the camshaft housing (see photo).





6. Before installing the distributor, check whether the engine has remained in its previous position, and if you have accidentally moved it, return the engine to its original position (see paragraph 3).

7. Position the distributor so that the rotor contact is in line with the arrow or notch on the distributor body (see photo). In this case, the tongue on the distributor drive coupling will be in the correct position to enter the corresponding slot on the camshaft (see photos).









8. Check that the O-ring is in place on the distributor housing and install the distributor in its place in the camshaft housing. After making sure that the rotor contact is still in line with the mark on the distributor body, install and secure the distributor clamping plate.



9. Replace the distributor cap, spark plugs and spark wires, connect the distributor wiring and vacuum tube.

10. Adjust the ignition (see section 19).

Engines 1.6 and 1.8

11. The procedure is similar to that described above for the 1.3 engine, except for the following.

12. The distributor wiring must be disconnected from the distributor, not from the ignition coil (see photo).



13. The distributor cap is not secured with screws, but with two spring clamps (see photo).

14. There is a mark on the distributor body for setting the rotor to the position corresponding to the flash in cylinder No. 1, but in order for it to become visible, it is necessary to remove the rotor and the flash protection screen (see photo). Once the screen has been removed, the rotor can be reinstalled to check its position.





15. The distributor is secured with two nuts, not a clamping plate (see photo).



16. The distributor is driven by a protrusion that enters a slot on the camshaft, and not by a pawl (see photo).
