Technical 57 Pontiac Power Steering Pully Deminsions Needed

As I am having trouble sourcing a cast iron power steering pulley for my 57 Chieftain, I am looking at alternatives that may work. Can anyone here tell me the face width of the stock cast iron pulley, the depth from rear face to the front mounting surface. Has anyone found a similar cast pulley that will work?

 

Here are a couple of pics of the pulley I am interested in for dimensions.
I believe the first image may not be a stock pulley for that year but the second image is.

 

I would check on Pontiac Performance Years...

 

Lots of stuff there but no pulleys. Thanks for the suggestion.

 

According to my Ames Performance catalog. The earliest one they have in OEM steel is 1965 @ $69.00. The earliest they have in billet aluminum is 1964 @ $210.00. They buy used Pontiacs as well, so you might want to give them a call to see if they have an original pulley off one of them at 1-800-421-2637. At the very worst, they likely can give you the dimensions you're looking for or maybe a cross reference. They're located on the East Coast, New Hampshire, I think.

The earliest Classic Industries has is 1960-75. They show it as being 5.75" diam.

You might want to check California Pontiac Parts as they are experienced Pontiac people. If they don't have one, they probably can give you the details you seek or maybe where you can find one. 1-877-504-8124 or [email protected]. They're located in Santa Ana, CA.

 

I believe Pontiac, Buick, Oldsmobile, and Cadillac all used the same power steering pumps in the 50's.
As such you can probably source a pulley from any of those makes.

Maybe try Steve at Pontiac Heaven or Franks Pontiac parts.

I have gotten excellent parts from the both of them.. Some say Frank is miserable to deal with but I have never had an issue with him, he sold me a perfect set of 8 lug drums..

Thanks I will give them a call on Monday.

 

Although all the pumps are the same the pulleys are not. I have no doubt that some may work but I have a 57 Caddy pump now and the pulley off set is to deep for my Pontiac. Some of the pumps also have 3/4 shafts the Pontiacs had a 5/8 shaft.

 

I tried Franks with no luck. I will look into Pontiac Haven

 

That pulley is for an AC compressor and it will not work according to the owner.

 

I doubt that pulley is for and A/C compressor, they have clutches on them. It appears to me to be for a P/S pump but FOR and A/C car, which may have a different offset. It may be helpful to ask for dimensions from that pulley just for comparison's sake.

 

You are correct on that being from a AC car I did miss state it as a AC pulley. I did contact the owner of that pulley who runs a large yard in Arizona and he confirmed that it would not work for my application. I have talked to at least a half dozen of those types of yards and most have no stock of PS parts that will work on a 57 Pontiac or they have complete sets of all parts and are unwilling to separate them.

 

Try Dave Reinhold at 618-284-3465 He's a old Pontiac friend.

 

Thanks, I will try and contact him later today.

 

Seller has other Pontiac stuff "if" you would have read further. Need only to contact him with request's.

 

I did contact him and as I stated above and he doesn't have any other pulleys for my application or individual parts for that matter.
