Correct alternator for a 1992 3fe

[bigezvol]

Alternator died on me this morning and I happen to have a spare 90 AMP I had already purchased. The problem is the Mountaineers on the bottom are way too narrow to fit in my mounting bracket on the engine block. Toyota indicates there are two alternators that came on this particular engine. An 80 amp and 90 AMP. The 80 amp has an external fan and regulator and the 90 AMP is internal. As you can see from the attached picture mine has an internal radiator and fan. However, the part that Toyota indicates does not have the correct mounting ears. Anybody have a clue if the 80 amp has the wider mounting ears on the bottom versus a 90 AMP? And if so how did I get one that had internal fan and regulator that has the correct mounting ears. The width difference of the mounting ears is 3 in vs 2 in.

There is a thread on this somewhere on this site. You have to basically grind down part of the ear to fit in there.

Yeah, the 90 amp was part of a "cold weather" package that also included a different motor mount. It can be ground to fit, I did this mod but the 90 amp alternator I had failed a few months later and I went back to the 80 amp one.

I have a 90amp in my 92, you just have to do a little weight reduction on the alternator. Pretty straightforward.

3fe 90 amp alternator?

My alternator went out a few months ago and I am finally getting ready to get working on it. I have researched the differences in 80 and 90 amp alternators for the 3fe and can't find a clear method for Identifying the difference. One post says the 80 amp has an external fan and I have read...

This thread shows how to modify the 90amp if you would like to do so.
Cheers!
