Thread: Difference in distributor bracket

Someone recently bought a new gasket set for the dizzy and it had two gaskets, one metal and one fibre - maybe the metal one is to make up the difference in thickness.

Ah ha, just realised you found it in the other thread

Yeah found the other thread, still having problems tho.

Is there a difference in the length of Lucas distributor? Do I have to find the original adaptor plate?

So I have worked out that my 45d replacement dizzy is 6mm too long for the adc2 bracket. Looking for the other bracket or the correct dizzy to suit.

Any one out there had the same problem?

6mm is a hell of a lot, more than just a gasket.

Now, please don't be offended, because I'm going to ask a really really basic question (the sort of obvious thing that's easy to overlook).
Have you tried rotation the dizzy through 180 degrees? They'll only drop all the way down in one place but if you're half a turn out, they'll key in but sit high.

Yes I made sure that was the case. I have measured the two brackets and there is a 6mm difference and no one seems to know why. (I must be Robinson Crusoe on this one). I have two part numbers if anyone can shed some light. #1 (old bracket) 247672 - This had the 24d dizzy in it. #2 (new bracket) 549610 (also has ADC2 on it as well.) I have a new dizzy as well (45d)

I think I may have the problem.


I have an early type engine, and i am trying to fit a late type dizzy. There is a 6mm difference between them.


Not sure if the drive gear is different?


If anybody knows of somewhere to find parts for early engines second hand I would be grateful.

The early and later engines have a different drive gear. The drive slot is offset in the later engines, if you are trying to fit a later dizzy with the offset drive to an early centered drive slot this may account for the 6mm difference. I think the drives can be swapped but not sure.
