If anyone saw a previous post, I found that someone had installed the wrong 2 groove power steering pulley on my car. I was able to find an original (or so it was advertised that way) 80 corvette single groove pulley, and I picked up a pump locally. I pressed it on today and it doesn't seem like it pressed on far enough before it aligned with the crank pulley. I've attached a couple pics, but there is around 0.45" of shaft left behind the pulley. It seems like there is a pretty good gap on the front side, between the edge of the pulley and the pump shaft as well. Anyone know how much gap there should be? Any help would be appreciated. Thanks!
It's not on the shaft-- the snout on the pulley should be flush with the end of the shaft. The correct install tool threads into the shaft, has a big bearing and a nut. The bearing rides on the pulley snout and as you tighten the nut, it forces the pulley on.

Yep, I used the pulley install tool rented from Autozone to press it on. I had no problem as it pressed on, I could just tell that if I press it completely on to the shaft it won't even come close to lining up with the third pulley on the crank. Maybe the pump i got from NAPA isn't correct?
Well darn, my pulley says GM 354324AB. Maybe it's not correct. Although it looks exactly like the pics of the corvette pulley, and it is the correct diameter.
Take a look at the AIM for your year- belt routing. I'd almost bet that the PS belt runs in a different groove on the crank. Only AIM I have is for '69 and you know they changed the routing between the years.

I thought the same thing, but the AIM definitely shows it on the third pulley. At this point I'm not sure if it would be a pulley or pump issue. I shimmed the pump out about another 1/8 inch, allowing me to further press the pulley on equivalently, but I can't shim the pump any further without it interfering with the alternator belt.

I cross-referenced your 354324 pulley number here and it doesn't appear to go to a 1980 corvette. Appears to be used in monza, vegas, and maybe trucks....

that part number I mentioned above from corvette central IS their own part number.
Per that gmpartswiki search it would appear that a 75-81 corvette would like use the following:
Yep, it all adds up.... here's the corvette central text from the page where the part number is cross referenced; I bolded the gm part number in RED

Thank you very much for all your help. I'm kinda pissed the guy advertised the pulley for a Corvette. Guess I should have looked into the part number further.
Of course, this pulley should work assuming all your other pulleys are stock and you have the correct ps pump for a 1980.

I'm trying to find the actual difference between my pulley and the 14023175, because they really look exactly the same in all the pics I can find. For me to make up 0.4" on the pump shaft, I would think the pulley would have to be shaped differently enough to notice. I'm confident my crank and water pump pulleys are stock. And they line up perfectly with the alternator, without needing any shims anywhere. I'm starting to wonder if my NAPA Auto power steering pump is wrong. I wonder if the front end of the housing should be slightly longer before the shaft starts. Which would take up that 0.4" distance between the pulley and the base of the shaft. It's too bad I can't just shim the pump further forward, but it's so close to the alternator belt that I think I'm out of luck with that as well.
There are a million pulleys out there and they're subtly different. If i was you I'd buy the 25 dollar 14023175 PULLEY on ebay and go from there. As long as it's not bent you can just paint it and it will look fine.
As far as the Power Steering Pump. I have actually ordered parts to buy (I usually go to autozone because it's near) and then if they come in, and don't look right, then I return them; or don't buy them. You could order a 1980 PS pump and compare it to the one you have.
There are also some 346289 (first part number for 14023175) pulleys on ebay. Prices are all about the same. From 25 to 90 bucks or so.
I got curious so I went and looked to see what part number superseded the pulley 354324 that you got.
In the gmwiki website.... looks like it was superseded by 14023172..... so I wondered if I could find what this thing really went to.... and I found this website:
I also saw other ebay sellers claiming 354324/14023172 went to some Corvettes, but I see no evidence of that anywhere else.
I bookmarked it for future use just the cool part cross-referencing and applicability .... anyway, within you can see what vehicles that pulley 14023172 went to and Corvette is NOT one of them.
AND you can look up 14023175 (the allegedly correct part number) on that oemcats website also and see pulleys for sale.....and you can see that it does go to Corvettes.
I do NOT know firsthand how different the pulleys are, but I don't think GM would make and still be selling 2 pulleys that are the same with a different part number if they didn't have to.
