Technical V belt rubs P/S install ‘63 Impala

With that particular bracket there isn't much room to move the alternator in a lot. Maybe enough to get the belt on. With no AC it should take a Gates 7565 that is 56.5 on the inside and 57.31 around the outside.

 

Kinda going far afield.

The alternator bracket is stock for a '63 Chev. '65 Chev use a different exhaust manifold and bracket; but still put the alternator in the same position. '63 & '65 use the same short pump and pulley.

The same alternator, water pump, and inner crank pulley have been on there and working for the OP; but haven't seen a straight enough on picture to judge the pulley alignment.

Seems the trouble started with the addition of the aftermarket PS pump bracket.

We retrofitted a '62 with an alternator on a stock GM '63-'64 bracket along with a PS pump on stock GM pre '65 brackets. All fit together. Been on the road for years with no grief.

Still think something could be fishy with the aftermarket PS bracket .

 

The frustrating thing is

yeah it’s a gates 7565

 

I tried pre 61 ps bracket and that didn’t line up the pulley but the alt fan was fine. Then I went with a universal bracket that lined up the PS pulley but the alt fan belt would rub the bolt. I went with the repop 63 brackets you see now .

 

Okay, speaking as a Shop Owner and a pretty danm good fabricator and being told everything is Right but it still don't fly it would be time for me to move on. We have already wasted Days waiting on parts and Hours of free labor shifting stuff around and it's time for it to get out of the Shop. Can't leave until it works so my solution is to build a factory looking spacer and raise the Alt vertically strait up till the dang Belt clears and close the hood. You're not building a Concourse car, you just wanted Power Steering. That would be Job Completed. Time to get back to making $$$$.

 

Can’t help but wonder why your pump won’t swing further to the right when facing the engine like this example…

For your consideration…

Speaking of different mounting for the Alt. I bet I could bolt this on and be done. I'd probably change it's rotation but you get the idea.

 

I finally got my whole ps system installed and test ran it. The belt is like 1mm rubbing. But it doesn’t seem like a real big issue for now. I’m still balancing the control valve and have a pipe I need to replace .

 

A little rub of the belt is like a little bit of cancer. You just going to ignore it?

 

It only rubs a little, won't be a problem for long.

 

Yeah, drive it, it's only 1 MM (.039), won't rub for long.

 

I’m waiting on that pipe and need to adjust the valve . So for now that’s all I can do.
