Distributor — disassembly, inspection and assembly (Opel Ascona C)

1. Before disassembling the distributor, check whether spare parts are available for sale. In some cases (in case of severe wear of the distributor) it may be more profitable to replace it as a whole.

2. Disassembly of the distributor should be carried out on a clean work table, where the removed parts can be laid out in order.

3. Remove the waterproof cover and the distributor cap together with the wires (if it hasn't been done yet) (see section 3). Remove the runner and plastic plate.

4. Remove the breaker (see section 4).

5. Remove the capacitor (see section 5).

6. Remove the retaining ring securing the vacuum regulator control rod to the plate shaft (see photo).



7. Loosen the screws securing the vacuum regulator and remove it, disconnecting the control rod (see photos).







8. Loosen the screws and remove the support plate (see photos).





9. Inspect and, if necessary, remove the centrifugal governor weights and springs, noting their relative positions (see photos).

10. To remove the roller, you must first remove the drive leash. Using a small punch, drive the pin out and pull the roller out through the top.

11. Clean all parts with a grease solvent and wipe them dry or dry with compressed air.

12. Inspect all parts for obvious wear and damage. Check the play of the shaft and inspect the teeth of the drive gear or the surfaces of the pawl for wear. Replace damaged or questionable parts.

13. Before assembling the distributor, lubricate all moving parts and centrifugal weight springs with grease.

14. Install the shaft and drive gear or pawl in place. Secure the gear (dog) with a new pin.

15. Assemble the centrifugal regulator, ensuring that the weights and springs are installed correctly.

16. Install the contact breaker plates and tighten the screws that secure them.

17. Install the vacuum regulator in place and tighten the screws that secure it. Connect the control rod to the shaft and secure it with a retaining ring. Apply a small amount of grease to the roller.



18. Install the capacitor (see section 5).

19. Install the contact breaker (see section 4) and adjust the contact gap (see section 3).

20. Lubricate the moving parts of the breaker support plate with clean engine oil and apply a small amount of high-temperature grease to the cam surface.

21. Check the roller for free rotation and the breaker contacts for correct operation. Use your finger to turn the runner in the direction opposite to its normal direction of rotation: it should return back to its original static position.

22. The distributor is ready for installation on the engine.
