   I screwed up....

When replacing a broken distributor spring, I forgot to mark which way the rotor post was oriented.  Does anyone know if this is correct?

I figure I have a 50/50 chance of getting it right, but if it is wrong, it will be a pain to disassemble and reassemble!!!

I guess I could figure out where the #1 wire is relative to the timing mark... That ought to be fun.  Any suggestions?  (other than to mark it next time!)

Hopefully I will be the last person to ask this question since I photographed this whole operation and plan on putting together a how to guide so that the next guy doesn't have to go through the pain I did...

Thanks,

Doug

	This is out of a 1989 351w. Hope this helps. Could you measure the slot length for me before you reassamble? Thanks Tom

	Tom, Thanks for the help... I could not tell if they were similar enough, so I just gave it a try and it worked... I had a 50/50 chance! Does anyone know if there is a way to upload PDF files? I wrote up the steps for rebuilding the Prestolite distributor (IBM-7007AS) including part numbers... Doug

	Not to be mean But if your having issues installing the rotor, which can only be installed one way as it's keyed, not sure of the value of the write up. Now if your talking about the distributor being pulling and then intalling it then that has all ready been posted several times.

	My problem was that I had a broken spring on the centrifical advance. When I removed the rotor shaft, I failed to mark where the key was for the rotor. When I went to reinstall the shaft, I realized that it would fit either way. I had a 50/50 chance on installing it correctly, or else the rotor would be 180 degrees off. It would have been nice if I could have found some step by step directions on how to remove and reinstall the whole assembly, so I thought it would be helpful. If it already exists, I couldn't find it... I am still working on how to adjust the centrifical advance because the springs seem to be a bit different tension than the originals (And difficult to find)...

	Yes it has been posted but I understand that sometimes it's hard to find things doing a search. Find TDC of the compression stroke of the #1 cylinder. You can do this by placing your thumb over the spark plug hole and feeling for compression. Stick a pencil in the plug hole and crank the engine until the piston is at TDC. Now, install the distributor so the rotor is pointing at the #1 terminal in the cap. You should be able to get the engine started to do the timing.

	if you are talking about removing the shaft from the base, then it doesn't matter. The rotor is keyed to the shaft by a machined feature. You can install the distributor in the engine block 180 out if you are on the wrong stroke of the crank. But you can not assemble the internal parts of the distributor 180 out not possible by design.
