Replaced my power steering pump a few days ago. Pump that was replaced I installed a few years ago and it was a real bear getting the pulley on it. I have the appropriate power steering pump pulley remover and installer tools that I bought at national parts Depot. I think why the pulley was so hard to install the first time is because I had pulley powder coated and that made the inner diameter of the pulley smaller where it fits on the power string pump shaft.

Fast forward to just a few days ago I went ahead and replaced the pump again and remove the pulley and once I got it off I used a Dremel tool with one of the sanding drums and just cleaned it out a little bit not a whole lot but just a little to make it easier for the install. Anyways it went on fairly easy with the install tool this time..

So today I started the motor up for the first time since the new pump installed drove it for about a half hour got back to my house and the pulley is backing out now on the pump shaft ...

I really don’t want to get another pulley. It’s still a pretty tight fit. But what I was thinking is what if I used red Loctite or even JB Weld and using the pulley install tool push the pulley back into position??

I understand that if I ever need to replace the pump again I’ll need to buy a new pulley but I don’t care ..

what are your thoughts;;; do you think that’ll work??

Just stick a bolt and a washer in the end of the pump. It won’t keep the pulley from moving aft but I don’t think that’s the tendency, more likely to move off the shaft as you’ve experienced. Use loctite on the bolt. You can also use loctite on the pulley.

If you mean you used the Dremel on the PULLEY then I vote for new pulley. If you used the Dremel on the pump shaft then it's new PUMP time.

WCCC does have them (used), at just shy of $100.

NPD has repros for $67.

I bought a 5Z-A1A pulley off eBay a year ago for $45 with free shipping. Larger pulley cures the over boosted condition of the factory PS
