Re: WJ power steering pump upgrade vs PSC pump upgrade

scratch that. after reading this http://www.pirate4x4.com/forum/gener...e-ps-pump.html

Did you ever try this on your MJ? Is it a HO or Renix MJ?

I have a WJ pump in my Renix Mj. I followed this http://www.bsfab.net/?p=152 and it worked out perfectly.

Re: WJ power steering pump upgrade vs PSC pump upgrade

Ok to dig up this thread again thanks to the attention given to me from another member on another thread I started in search for information on this swap, what is the general consensus on drilling out the high pressure fitting from my XJ pump?

Also, how did y'all plug the other fitting on the reservoir?

Re: WJ power steering pump upgrade vs PSC pump upgrade

General consensus was to leave it alone and not drill it out, as drilling it caused it to whine.

I believe you can use, if you want, the other port to attach a power steering cooler. I've found a write up that a cooler from an F250 mates to the brace behind the bumper without much issue. Even mounting holes line up.

Re: WJ power steering pump upgrade vs PSC pump upgrade

Definitely doing this upgrade. I found my 87 XJ was ok with 33s turning. My 00 XJ with 32s is heavy feeling.

Have you done the upgrade? Any tips on how to do this? Did you have to mode the low pressure line like in the write mentioned here? http://www.bsfab.net/?p=152

I have a 97, so I shouldn't have to do the mounting stuff.

How did you plug the extra hole that the WJ pump has?

Re: WJ power steering pump upgrade vs PSC pump upgrade

R6TeXJ - I tried to do the WJ pump upgrade. The pump I had kept leaking out of the connection between the pump and the reservoir (reinstalled 3 times with new O-rings each time), so I just tossed my OEM one back in with a new reservoir.

When I installed the WJ pump, I didn't have to do a lot of what they said on that write up. I certainly didn't tap and thread the WJ pump bracket - there is no need, I didn't have to tweak any lines, I didn't drill out the XJ pressure line fitting. It really should be just a direct swap...with the pressure line fitting change. Next time I would try to do that change with a wrench and not a socket. I took the WJ pump and reservoir apart to move the fitting to fit the socket in and I think that I never could get it back together solid. I believe that if I had never fiddled with the reservoir separation I'd have been fine.

The extra hole, I left about 3 inches of hose on it and then stuck a big ole bolt in the end and hose clamped it down. It was suggested to me later that if I'd left about 6 or 8 inches, I could have folded up that soft line into a "U" and eliminated any possibility of fluid escaping between the bolt and the hose clamp.

I also did use a junk yard pump so that I didn't have to deal with moving the pulley from one unit to another.

Re: WJ power steering pump upgrade vs PSC pump upgrade

thank you!

While you had it could you notice a better feeling while turning?

Thank you for your help! I'll think I'll try and tackling this mod this weekend.

Ok so what I did is I used the lower return fitting and got a small piece of larger hose at the parts store because thew fitting is too big for the stock return line. I then went to the hardware store and got a reducer fitting to then drop back down to the stock size. For the smaller fitting on the on the reservoir, I originally capped it with a silicon cap from the parts store. That thing leaked like crazy even with a clamp. I finally took a small piece of hose and clamped it and then stuck a bolt in the other end big enough to fit in the hose and then clamped to that and that stopped the leaking. Aside from those two slight adaptations, the rest of the install was straight forward. I swapped my original pulley to the WJ pump because my 97 had a metal pulley while the WJ stock pulley was plastic. I also of course swapped over the fitting for the high pressure side like everyone else did. Turning seems slightly easier but not drastically. I did a lot more internet researching and found more threads discussing whether or not to drill out the high pressure line fitting. I found an interesting discussion where one guy tried drilling it out larger but not to the same size as the stock WJ fitting. What he was saying is that drilling the hole out to the same WJ size but trying to force it down the smaller XJ line with less things that all that volume of fluid has to run would cause the pump to capitate creating the noisy pump that everyone seems to complain about. He drilled it our larger and it gave him more power but it didn't create the loud pump issue. I wish I could tell you what size that was but I cannot find that web page again to tell you what he drilled it out to. I had planned to pull the fitting out and drill it out to the size he did after the dust settled moving into out new house.

Re: WJ power steering pump upgrade vs PSC pump upgrade

Found it! Post #7 goes over what this guy did when he put a WJ pump on his TJ. He drilled it out to 3/16" and he says it doesn't make the horrible noise but increases power.

Re: WJ power steering pump upgrade vs PSC pump upgrade

I run a WJ pump and Durango box and LOVE it. Huge difference over stock. Turns my 33's with no effort. As said don't drill out the fitting. All you need to do is swap it. You don't need to tap the pump I just got a longer bolt to go all they way through. Even that is overkill though. My biggest issue was the second line fitting. At first I had a hose with a plug with a clamp and that didn't last, crapped out driving one day gushed fluid everywhere. After that I put a new hose with a bolt and filled it with RTV or any oil resistant silicone clamped it and it's been fine. I went with Lares for my reman, they are based here in the states and cost wise and not bad, a lot cheaper than a PSC or red head rebuild. I also ran all new lines, with a aux cooler, filter and Lucas fluid. Worth every penny IMHO.

I've read through that post a few times, just never noticed where he with a smaller drill bit. I'm thinking of trying the non-drilled version for a moment and see how that does. Then if I need to I can always drill it out to the 5/32" that he mentions.

Longer bolt where? sorry not understanding.

I'm thinking of getting one from Oreilly's From work I get a discount.
