Tmac Posted May 30, 2023 Share Posted May 30, 2023 I bought a new power steering pump and pully. I have it installed and washers between the mounting bracket and pump and I still can't get it to line up with the crank pully. About half a groove off. The pulls slide right on but, seems like it is bottomed out on the shaft. Any ideas? Quote Link to comment Share on other sites More sharing options...
jft69z Posted May 30, 2023 Share Posted May 30, 2023 Are they the original brackets that you had used before? 1 Quote Link to comment Share on other sites More sharing options...
Scott S. Posted May 30, 2023 Share Posted May 30, 2023 Have you tried the single groove pump pulley ? It may be matched to the crank pulley you're using. Quote Link to comment Share on other sites More sharing options...

No, I took a double off and I plan on putting the AC back in. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted May 30, 2023 Share Posted May 30, 2023 Put the water pump pulley on and see if it lines up with one of the others. If it lines up with the crank pulley, you know the p/s is off. If it lines up with the p/s pulley you know the crank pulley is off. Try that first and let us know the results. 1 Quote Link to comment Share on other sites More sharing options...
snomobeelr Posted May 31, 2023 Share Posted May 31, 2023 Maybe its the angle of your picture but it looks like the P/S pully is not on all the way? Heres mine 2 Quote Link to comment Share on other sites More sharing options...

The alt/waterpump pully line up great. I'm sure it's the p/ s pully just don't know why. It seems like it's on all the way, as in bottomed on the shaft, But doesn't look like it looking at the bolts. As snomobeelr pics show. Quote Link to comment Share on other sites More sharing options...

Tmac Posted May 31, 2023 Author Share Posted May 31, 2023 UPDATE: I found the old cracked pully and measured the backspacing definitely different. Again I took the hard route to find it out! LOL. Now I'm in search of the right one. 1 Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted May 31, 2023 Share Posted May 31, 2023 Glad you found the issue. I was just going to take a pic of Barn Find to compare with the other pics. 1 Quote Link to comment Share on other sites More sharing options...
NavyCPO Posted June 1, 2023 Share Posted June 1, 2023 Glad you found the problem. So the one you need is 1.098? Quote Link to comment Share on other sites More sharing options...

Found it at The Parts Place. Works good now. The belt is on the wrong groove but its just to test the line up. 1 Quote Link to comment Share on other sites More sharing options...
cny first gen 71 Posted June 16, 2023 Share Posted June 16, 2023 Maybe it's just the angle or not on all the way or my eyes but do them pullys line up ok? My ac pully was off a little but was always ok. Quote Link to comment Share on other sites More sharing options...
jft69z Posted June 16, 2023 Share Posted June 16, 2023 Terry, I posted a question on your FB post about a spacer on the front face of the pump. What year is it, and is part number 10 on the below diagram there? (it could be an easy one to forget to install and maybe cause alignment problems, just a thought). Having to space it out with washers like on your FB pic isn't normal. 1 Quote Link to comment Share on other sites More sharing options...

I think the true test will be when I get the ac compressor on, and see how it all lines up. 2 Quote Link to comment Share on other sites More sharing options...

Having to space it out with washers like on your FB pic isn't normal. I agree about it not being normal. I also had a thought about the water pump mount, where that bolt # 8 goes in. If that casting was just a little thicker or moved towards the front a 1/4 inch. Just a thought. I'm reluctant to grind on the water pump to move the ps pump back towards the block in fear of not getting it square. Then the pickle I'd be in🤷. Any thoughts?

I was thinking about that water pump mounting boss as well. Do you have any old water pumps laying around to measure from the block mounting surface to the front of the p/s mounting area? If that's off, well, that is an obvious problem. Most of what I have here is big block stuff, but may have one on a 350 LT1 I have under the stairs in the basement. I'll check in a bit, it's buried pretty deep 😁. Quote Link to comment Share on other sites More sharing options...

Just need to head out there and dig it up. I'll try and do that this morning. 1 Quote Link to comment Share on other sites More sharing options...
