why is my alternator bolt hole supports reversed?

[Guest Anonymous]

picked up an alternator from a junkyard. looked like it would fit nicely into my 72tii. when i stood it next to my normal alternator i noticed that the two bolt support holes are reversed.

on one side is a long bolt support bracket (that mounts next to the block) and the other is short (that one fits into the extention arm that reachs out from the block above the alternator).

the long and short bolt supports for the alternator i picked up are just the opposite. when i fitted it to my 02 it wouldn't let me fit a fan belt on it. the front of the alternator lines up with the other pulleys - it just is too far out to get a belt around it.

anoyone else had this experience? is this alternator from the wrong model bmw to be brought over to my 02? any mods I can do that would allow me to put this one on? i'd like to put it on if possible - the bushings on my old alternator are just about shot.

thanks, tim

I don't know of any other that will fit. G

or take it to an alternator shop and have them do it.

i posted a long-ish how-to-do w/ a couple pics on the roadfly board a few weeks ago. if you use their search engine you should find it. that will expalin why tii alt. upgrades to non tii alt. are very specific . or, as was said, you can just rehab your 45 amp tii alt. with new bushings.

You can fit the 55-A/65-A alternator (Bosch AL41X) from an E12 to a tii if you add a spacer or stack o'washers on the long pivot bolt. I have spacers.
