Now I've gone and done it... Scored a great condition BMW 325is for a song and have been driving it for some time until the Alternator gave up on me yesterday. Finally removed it (no hair left) and chucked it up in the lathe to see if I could get anything out of it. Nothing. Had 3 options1) get a new Alternator - BMW wants over $600 for a new one - Wreckers have none 2) Get the alternator rebuilt 3) Futz with it myself Being a frequenter of this group I chose option 3 and thought to work my way backwards through the list above as options diminished. In trying to get the alternator apart to look at the guts, I "tapped" it too hard with the dead-blow hammer and sure enough BROKE the mounting bracket clean off - looks to be cast aluminum and none to good a casting at that - many inclusions. Question - Can I TIG the bracket back on (what filler?!) I think I can make it structurally "sound" but will I fry the coil insulation / other goodies in the process (still could not get it apart so I have to weld it as a unit) and then get it rebuilt or do I just keep looking for a used one - or GULP buy a new one?
Sorry for the long post and thanks for your help guys
