Alternator Removal '81 FI

[ralphcap]

I've been unable to remove the bolt holding the alternator to the mounting bracket (lower bolt). It won't budge. Had no problem removing the pivot (tensioner) bolt. Here's a photo of the bolt from the back of the alternator. The bolt is 19mm and I used a socket on a 25 inch breaker bar to no avail. What am I doing wrong? Any suggestions for removing this bolt?

I applied some penetrating oil when doing mine.

Tap on the bolt with a small hammer when it is soaked in penetrating oil, it helps get it down into the threads.

You are not doing anything wrong.That bolt is just rusted in there real tight. As stated above penitrataing oil and a hammer
plus a lot of patience. Just keep working with it some today some tomarrow ect and you will get there. If you have a zip
gun(air chisel) they are a big help with something like this. If the radiator is out then a inpact gun also is helpful. Just take
enough time not to break anything. For now some fluids would likely be in order.

I was going to upgrade my 81 to the 95 amp alternator when I ran into that exact problem. I posted for some help and got some suggestions.

I did some searching and found this:

Watching an alternator and mounting bracket get torn apart scared me enough that I bolted the alternator back on and never switched it out. I ended up using the 95 amp alternator on a different car.

Hope yours is less locked up than mine was.

After about a half can of penetrating oil and almost a month of on and off work I finally got the bolt to back out far enough so that I could tap it out with a trim removal tool and hammer. Phew!

hopefully you will coat that bolt with anti-seize before it goes back in
