So I've been slowly gearing up for a rebuild for a while, figuring that with my old alternator having failed and a garage big enough to do the job, I may as well. It's a 1980 BJ40 with a 3B in it, 12v. Part of that rebuild is, of course, dealing with the alternator. My old one gave out, so I found a used one from Canada. It sat on a shelf for a while, but since I've finally got a bit of time, I decided to haul it down to a local alternator shop to figure out the best way to clean it up, have it tested, and get some advice on machining corrections for the mount ear holes, which were in bad shape, and maybe see how much a rebuild would cost.
They flatly said that it'd be pretty much impossible for them to rebuild it -- they just can't get the internals. Furthermore, as soon as the main repair guy picked it up, he noticed that the shaft was loose enough to knock around -- evidently, the bearings are well on the way to being completely shot.
So now I'm left with a problem. My vac pump is a coarse spline model, and I can't get a new alternator in anything but fine spline models. That means I'd need a new vac pump, which I understand is hideously expensive. I've also heard that electrical vac pumps are an option. So is there anything else I could try? If not, what would you guys suggest for replacements, vac pump & alternator wise?
