Distributor rebuild

[Nordical25]

Now you have basically cleared the toughest part. Test before assembling distributor further that new bearing has no noises or too big play. If it does, unfortunately it is time for new bearing + oil seal rebuild.

If everthing is ok, you can put back together vacuum advance + pickup poil plate. Fasten them well with three screws.

Then remount ignition control module and distributor wires with five screws.

Then you can continue into distributor reluctor. Put it back and see that it won't touch pickup coil in any position. If it will, you need to readjust pickup coil from two torx screws. Reluctor should never touch pickup coil or it can cause damage while driving the car.

Then put back ignition coil and plastic covers of ignition module and ignition coil. Now you have fullly rebuilt distributor that needs only test driving.

Assemble distributor in exact same position prior to removal. Check also with light that you have now correct ignition timing or readjust your ignition to 10 degrees. Now you should be good to go. Good luck.

Inner oil seal. Size 10mm (inner diameter) /20 (outer diameter)/5 (thickness)

And here are the goodies if you want everything new:
Vacuum advance

Reluctor
Pickup coil (needs adjusting correct distance)

A small update for distributor rebuild. I have recently found out that latest 4A distributors came without pin/key gear on the distributor shaft. The gear on such distributors is basically a one centimeter thick gear. You want to have access to hydraulic press if you want to rebuild a 4A distributor with press fit gear.

Do you have a picture of the pin you're talking about? I think I know the one, I think it's the wavy thing that looks like a tiny crow bar, but just want to confirm.

Here is the comprarision of the gears. First distributor is from 1987 Carina II and second one is an European spec. Tercel 4wd distributor with points.

If you look carefully, you will see a pin holding Tercel distributor gear meanwhile Carina distributor has only bare gear with press fit.

Ah, gotcha. Thanks. I was thinking of the internals of the dizzy so I was mixed up.

You are welcome. I understand. There is also a pin/key holding distributor reluctor.
