I’m having a few difficulties installing an alternator conversion kit. I’m convinced the materials are good, but I’m addressing fitment.

The instructions contain a “warning“ that it may be necessary to file down the rear flats of the alternator to achieve alignment. I took about 3/32 from an inch off the main rear flat, but I still can’t achieve proper fitment. It appears that the little shoulder ridge of my front engine plate is interfering with the alternator case, but only slightly. I can file it.

I’m just curious whether others have had this issue and whether it would be typical to have to file as much as 3/16 of an inch off that main rear flat on the alternator?
 
I put a GM alternator, 7127, (10SI?) on my 1960 TR-3a. I had to file a lot off the case and change the alternator adjusting bracket. I got a bracket off a Jag XJ6. Its worked fine for 21 years.

What alternator kit do you have and car?

Good luck, Roy
 
Tr4A and kit from British Wiring. I just got it installed finally. And I did have to file that rear flat down about 3/16 maybe a bit more. I also had to grind down that curved adjusting bracket.
