Alternator - 1974 911

I need a replacement alternator. 

The knobs who rebuilt mine, appear to have dropped it, and welded it. The fan now spins with a bit of resistance so I assume it isn't true anymore. Getting my money back etc is a separate issue, but for now, I need to find a replacement.

Can anyone help out?

They tried to tell me there were "hairline" cracks in the case which needed reinforcing... bullshit i say.

Even if I get all my money back, I still end up with an alternator which is now useless, not useable. But again, it doesn't assist in my quest for a working example.

Fatigue cracking was my first thought before I'd read the next posts.  Welding the housing would cause distortion from the heat. Unless the bore is machined true, misaligned bearings could cause the resistance to rotation.  The repairer should've notified you immediately on discovery of the cracks and stopped work.  I think instead they have tried to save a few dollars and done a quick fix.  The result is one junked alternator.

hi Peter

yes, I did see that, but mine looks more like this one...http://www.ebay.com.au/itm/251825685282?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Same seller supplying them. 

Mine has the external regulator, which the link i posted also specifies. 

I'm guessing the link in your post is with an internal regulator? I have shot off an email and will wait for a reply.

Sorry Mike, I didn't intend to suggest that was the "one", more to suggest they're available at a reasonable price and it's not the end of the world!

Probably comes down to how quick and how much messing around you want to do too.  Do you buy one completely reconditioned, ready to bolt on or do you seek out a cheaper one just to rat the front cover so that you can replace your damaged one you have? 

At the very least I would expect your very reputable motor engineering firm to swap over the covers free of charge if you supplied a replacement?

Isn't there some world famous Porsche alternator rebuilder in Brisbane that does exchange units for Pelican or Rennparts?  I'm sure he's been discussed on the forum previously?  He might be worth a phone call and may have a cover ready to go?
