Generator bolt holes


Post by panz4ever » Tue Nov 07, 2006 5:27 pm

I am putting a 49 EL together. When I got it the original generator had been removed and updated to a 12 volt system. I am having the original rebuilt and intend to run it as a 6volt w/ the correct 32e generator. When the 12 volt was put on the holes were enlarged in the cam case cover to take the bigger bolts. I have the original 1/4 inch bolts. (Later style take the 5/16 style.) Anyone have a source that makes a sleeve for the enlarged bolt holes or perhaps a shoulder style bolt that goes from 5/16 down to 1/4. Trying to avoid filling and redrilling holes if possible.

Is it a possibility to adjust the 6V generator to accept the bigger bolts?

I believe you can drill and tap the Gen. from 1/4 to 5/16, you will not need to shim and strap the Gen. because of the larger bolts, but you can if you want. There should be plenty of meat in the Gen. mount plate to do it . I know some have installed Helli coils to repair the 1/4 threaded holes, so drilling them out with the proper alignment and drill for the 5/16 tap should be no problem. Now if you don't want to change the hole sizes in your Gen. to keep it stock , well thats another thing.

Someone has messed up a good part in the past and now you are talkin
about messing up another to make things fit. Get someone to fix your case.
my humble opinion Fred
