Hello all,
Last summer I had to replace the power steering pump in my 87 F150. Unfortunately the pulley was damaged during removal (don't ask) and I found a new one on ebay. The truck ran fine all summer but I had to go out of town for over a month recently and when I got back and started the truck up, the belt is trying to come up over the outside edge of the pulley and making lots of noise while it does it. Why does it do this now and not all summer? I kept the old damaged pulley and the part number reads E7TA3D673EA. The one I got from Ebay reads E8TA3D673-AA. Are these pulleys two different sizes? The eBay add just said something to the effect of "power steering pump 87-90 ford 300." I assumed they were all the same...did I make a big mistake here? If so, where do I find the right pulley? I hope you all are having a better day than I am lol.
Does the belt just come up over the edge of the power steering pulley?
At any rate, I would remove the serpentine belt and check all the pulleys for looseness. Especially check the water pump for looseness based on some trouble I recently had. You can't check the water pump for looseness when the serpentine belt is installed, the water pump will seem tight when the serpentine belt is installed.
Also the power steering pump will probably naturally have some back and forth play.

Yes, the power steering pump is the only pulley it is trying to climb over, the rest are fine. The water pump is brand new with all new hard ware. Ill try yo post a picture of it. Its rather frustrating.

Show us a picture of your underhood things going on. Show us the belt tensioner, the pulleys, esp the ps pulley
Did you install the pulley using an installer? Or just the bolt nut and washer they give you with a reman power steering pump?
If you used the bolt, the pulley will not be on there all the way. That has been my observation over the years
Rent the special tool
Leave the belt in place and push the pulley on there some more with the installer
The pump shaft should protrude out of the pulley by abought 1/8 inch
You might have to remove the fan and the shroud to get the tool in there

Yes, it was installed with a power steering pump pulley removal/installation tool. The pulley is seated properly. The belt is trying climb over the forward edge of the pulley, if it goes back further the problem will get worse. I really think I have the wrong pulley, I think the off set is different than the original. I tried to post a picture on here but it keeps telling me the picture is in the wrong format...
Are you re using the belt that flipped?
Turn it around?
Sometimes the serps will take a set after a flip and will flip over and over after that
If the pulley is flipping the belt to the rear, adding washers or spacers behind the bracket will not help either
I think some of those 4.9s had thin spacers behind the P/S, A/C bracket IIRR
Those 4.9s have the same power steering pulley as all the rest of the V8s?
NAPA does not differentiate. They show this one
Your phone camera should take a photo and it will be jpeg format
If you grab a photo off the internet it might not be jpeg

I finally got the picture to upload. That's actually better than it was, but see how the belt is trying to climb over the pulley? Its like the pump needs to come forward toward the radiator somehow, but it can't because its seated properly against the bracket, and the bracket can't move anywhere either. It worked fine all summer with no problem, then sat while I was gone for a month and a half and when I got back and started it up, that's what it does. I don't get this....
Maybe post a pic from vertical to see alignment. Is it possible the main bracket is not fully seated causing the whole assy to be out of angle? Could have been out whole time and belt just finally gave up. TBH I throw parts at problems until it gets fixed but if belt seems good on upstream and downstream pullies may be a good exercise to remove pump and bracket and ensure its seating correctly, no trash or crud in-between the faces.
Try removing the belt and turning it over, then retest
While off, see if any of the other pulleys seem to have trouble. like a loose tensioner or water pump pulley

the question on the pulleys being different, iirc the 4.9 pulley is a smaller diameter than on the 5.0/5.8

the walking can be caused by that tensioner pulley which looks like it may be a replacement for an old tensioner? if the tensioner arm is bowing away from the tensioner body that will ride the belt one way, and the pulley on the shaft can be moved because ford calls for initially setting it flush with the shaft then adjusting it to account for belt alignment
