Help removing power steering pump pully

I am replacing the power steering pump on my 1974 CJ5. While waiting for the new pump to arrive, I pulled the old pump and am trying to remove the pully. There appears to be a 3/8" Hex head bolt holding the pully on, but I cannot budge it. I saw on some other sites that there is no bolt and the pully is just press fitted on.

So does mine have a bolt? If so, anyone have any advice on how to loosen it? ... I assume it is a right hand thread...?

 

Does the pulley under the bolt have a groove around it? If so someone may have put a bolt in the shaft. The ones with the groove around the "hub" part of the pulley are pressed on and require a pulley puller.

There were some that bolted on but they're few and far between. The pulley has a key slot and the pump input shaft has a woodruff key. Post up a picture, it's pretty easy to tell if it's made that way or if somebody did a little creative engineering. Problem is if it's made that way, your new pump has about a 99.9% chance that it needs an interference fit pulley.

 

Doesn't look like anyone has "bubbafied" it by adding a bolt. I also see that the center of the shaft is threaded to recieve a pully installer.

 

go to local parts place and rent power steering pump pulley removing tool - its the only way to get it off shaft

 

Yup. Or buy one. You will need the installer tool as well.

 

Not a big fan of Harborfreight tools but for $20 I haven't broke mine, yet. http://www.harborfreight.com/pulley-remover-and-installer-set-40749.html Much rather would have had another Snap On but couldn't find one reasonable when I was looking. If you're not getting a new pump you'll want to get a 3/8-20 tap to clean the threads inside the shaft too.

 

X2, 'round here Autozone or O'Rielly will loan you the tool you need to remove that pulley....won't take you long with the right tool.... GOOD LUCK!

 

Success!!! I bought a puller/installer kit from AutoZone for $29.95. Worked well so now I am ready for when the new pump arrives......

 

Not sure where you're getting you new pump from, but I got mine from PSC and it was definitely ordered for my model year, but the shaft was the wrong size and no key. I called PSC and they said it wasn't a problem; sent it back to them and they changed out the shaft for the shipping cost. Thought I'd mention it just in case.

 

Who is PSC?? Not sure I have seen their site. I ordered the first one from Morris 4X4 but it was the wrong one when it arrived so I returned it. The second, I ordered from JCWitney, but it is still in transit. Hopefully, it will fit when it arrives.

 

Going stock shouldn't be a problem hopefully. PSC Motorsports is where I got mine (pscmotorsports.com)

 

I hope mine fits when it comes back too. It fits the bracket no problem (304 stock bracket), but the pulley didn't seem as though it would line up if I could have put it on the shaft. They told me the new/correct shaft would resolve the alignement issue also. We'll see!

 

Well the 3rd power steering pump arrived and is now installed.....finally. The first one I ordered from Morris 4x4 was the wrong one. I knew my system was a later install, so I used the pictures on their website to order.....bad move as the pump did not match the picture. There were happy to send it back and give me a full refund. The 2nd pump was from JCWitney and was close, but had a keyed shaft and nut instead of the press on like my old one.

I finally got smart, and took pictures of my old pump and sent them to Cardone.com. They identified the correct pump and I ended up ordering it off of eBay. Should have done that on day one.....oh well lesson learned.

Back to the subject of the original post, I ended up buying a pulley puller/installer from AutoZone. They really wanted to lend me one, but I like to buy tools so I have them so I bought one for about $30.00. Worked really well. (I did have a small center collar puller from Harbor Fright, but it was useless as it was too weak to keep in alignment)
