power steering pump & pulley flush??
I have a 2000 Grand Cherokee v8. I bought a new power steering pump and pulley. I put the new pulley on the power steering pump. I am about 10 to 15 sheets of paper thickness away from having the pulley to the shaft flush. 1/32" or 1/64" ?? I really don't think it would bother the belt. Has anyone else been that close of being flush and called it good and didn't have a problem? The bolt that came with the pulley stripped while pressing the pulley on. I bought another bolt and square nut. That bolt broke in half while trying to get that last distance of being flush. Any help would be appreciated.
Thanks, Dan

I did buy a grade 8 bolt but really don't wanna use it in case it can't go on any further and I end up stripping the threads inside the shaft.

I will try and look at mine when I get off work, I don't remember how close mine ended up.

That would be great if you could.
Thank you

According to the manual you have to put the pulley on flush. Then you have to run the engine for 5 minutes and hear if the serpentine belt is noisy. If it is, you have to pull the pulley 0.5 mm from the pump shaft and try again. When worse, you have to push the pulley on 1.0 mm and try again. So i would say, try it first and if it doesn´t make any shirping noises, its ok.

I'll try that. I'm changing it tomorrow afternoon after work.
Thank you

Re: power steering pump & pulley flush??
This is probably a good time to change all the fluid in the power steering system. There is no scheduled maintenance task for this, but the system is always working when driving and there is no filter to clean the fluid.
When running the pump for the first time, a lot of foam will be formed and ends up in the reservoir. After half a minute of operation (and using the steering wheel to get the air out), stop the engine and let the foam sit for a few minutes, so that it becomes fluid again. Then refill the reservoir and run again for half a minute. Do this until almost no foam is present anymore. If your jeep has the hydraulic driven cooling fan, you could shorten the deaeration time by disconnecting the coolant temp sensor connector (in between the alternator and AC compresor), so that the cooling fan goes to high speed and increases the fluid flow. It will make a lot of noise and keep hands and loose clothing far away from the fan. The downside is that you need a scanner to reset the check engine light afterwards. (due to the connector removal)
The fluid is some MOPAR stuff, but i use an other brand synthetic fluid for power steering systems. Do not use tranny fluid.

I am going to bleed the system when I'm done. And I will try to flush out most of the old fluid the best as I can. Not sure if I have the hydraulic driven cooling fan but even if I do I'm not going to unhook the coolant temp sensor connector. 1st I don't have a scanner to reprogram it and I don't mind taking extra time to bleed it out. Thank you for letting me know.

Sorry I didn't get a chance to get a pic yet, snowing pretty good here. When I changed my pump I filled it slightly over full to start and left the cover off so I could add more while bleeding the system. That also seemed to help keep the foaming down.

Re: power steering pump & pulley flush??
I changed it last Friday night. I flushed the system. Wow that was BLACK! Now it's nice and clear. :D After all that the pump wasn't leaking. But I already bought the pump and put that pulley on. I knew they wouldn't take it back so I just put it on. (Pre-maintenance) :lol: After letting the engine run. I didn't hear any winning sound or noise from the pulley not being completely flush. So I took the old belt off and put the new one on. Still no noise. Wife and I both think the steering is tighter now. Which I think would be better. lol Just gotta fix that leak or replace the box.
Thank you all for the help. :thumbsup:
