Just get a new pump from RockAuto

I had good luck with a new pump. You just can't put the pulley nuts (3 of them)
on too tight or you crack the pulley input shaft where it is cast out of some cheap
pot metal.

As an update to my post, I seperated the original bearing from the output shaft of the power steering pump today. I had to heat the shaft up in the oven @ 250 degrees & consisted of multiple attempts at removing the bearing from the shaft. Tomorrow will be a combination of heating the output shaft at 250-deg again, while chilling the new bearing in the freezer in order to mate the interference fit. I have to find or buy a washer that will allow me to press on the bearing & also clear the output shaft on the inside diameter. It should be much easier installing the new bearing than it was to remove the old 1. Harbor Freight sells a bearing/race driver & separator kit that might work, as would a puller once you are able to gain some clearance between the orig' bearing & the pulley flange but I was able to get them seperated with a couple of screwdrivers, 4x4 block of wood, BFH, & the oven of course. I had too much going on to drop everything & drive across town @ rush hour so I made it work but I'm going to be more deliberate with pressing the new bearing after I get the shaft & flange polished up & the ideal tools for the task. I will order the re-seal kit this week and update the thread when I receive that stuff & wrap-up this little exercise.

 

I have also been rebuilding the idler pulleys & AC compressor output. There is a good, recent thread for the AC bearing, which I bought at AutoZone. The larger, driver side idler takes a 6304, the PS pump is the 6302 and the smaller 70mm passenger side idler is actually a 6203, so don't get it confused with the PS 6302 like I did. I was up to my neck in these bearings chasing down a noise in the drive-belt so this is just a side note to the PS Pump rebuild in the event someone else is chasing down a noise, maintaining or otherwise & being hands-on like me would rather fix what you have while burning some daylight. If I'm not mistaken, the alternator has an accessible output bearing as well; I believe I ran across a thread discussing that topic so I will edit this when confirmed, to also include the alternator output info too.

That's the same seal kit I put in my leaky spare pump I carry in the rig...I hope if I ever need to use it, it'll work.....

 

I hope that it works for you, too!

 

Consider this post before you spend too much dosh on refurbing the pump.
