2nd alt vs air pump ?

[Gundy]

OK, so the air pump on our 1983 fj60 seized...again.
I'm sick of replacing these things. Truck is de-smogged.
I'd like to install a 2nd alt in the pump's place.
I also have an alt from an 96 fzj80 lying around.
Will it bolt up? Will I need any special type alt for
this setup? Special bracket?
Any tips ? TIA

Do some searching. I think people have used a GM alterator in the smog pump location. If your smog pump went out again, I would make sure you don't have some other problem causing it to go out. Your air cleaner have oil in it? I would try and find a Bosch alternator that would fit. They make good alternators with external voltage regulator with the brushes.

Is your PS pump leaking fluid onto the air pump? Common cause for air pump failure.

I had the Delco one-wire alternator in place of my smog pump and run to a 2nd battery. Two separate charging circuits. Worked well.

Thanks for the input guys.
My p/s pump doesn't leak.
Air pump is clean and dry.
It doesn't connect to the air cleaner
as the truck is de-smogged.
Air pump just serves as a belt adjuster.
At present I don't care if the alt is even connect to
the truck's system. I'm going to try to use it
as an adjuster.
I'll post my results when I remove the air
pump.

Why not just gut the smog pump and replace the bearings? Much cheaper. You could buy the smog replacement tensioner pulley also from $OR.

Just thought.

Hmmmm....I think I'll check the $OR unit out! Thanks!

change of plans

I went with the eliminator bracket from SOR.
The simple solution. LOL...cheaper than an air
pump for sure.
Thanks Mark! This forum never fails me.
