1983 CJ7 Power Steering Pump Dilemma

Hello,

I have been slowly stopping leaks in my CJ7. Recently, I have began attempting to stop the power steering pump leak which occurs between the pump fluid housing and the high pressure union. I purchased a remanufactured Cardone power steering pump from Advance Auto which was listed as working for this vehicle in an attempt to curb the leak. However, the low pressure return line attachment is in a completely different location. Some models of the power steering pump on Quadratec have this part routed similarly.

The first picture is of the power steering pump currently in the jeep. The second picture shows the fact that the return line is not where it is on the current pump. The third picture shows where the return line is on the new pump.

The questions are:
1) Will this power steering pump work even with the return fitting routed differently?
2A) If not, should I buy the $15 seal kit, take the pump out of the fluid housing and replace the seal that is leaking (should not require actually tearing into the pump itself)?
2B) Do I break down and buy an identical crown power steering pump?

Thank you!

Hopefully this will help others who are going down similar routes as well!

The correct housing is what you had, not what you bought.
If your leaking at the high pressure fitting, make sure you have the matching hose and pump. There are two styles and I believe the changeover year was around 1981. The older style is an acorn fitting and the lighter style uses a rubber O-ring

If those are mis- matched meaning 0lder pump and later hose or later pump and earlier hose then yes you will definitely be fighting leaks there

I got my pump from NAPA but it was hard to get. At the time there was only one in the US but that was a year or so ago. I know people have mixed feelings with Crown and Omix but Napa power steering pumps are not made by or remanufactured by crown or omix.

If you have access to a NAPA, the part number is NPS 81-8539. Thats what mine was, Which is what looks like in your first picture.

The new pump looks like it is from an 1984-1986 4 cylinder XJ, that pipe going up to the top shoulder, if it was cardone part 207877 then it is not from a cj7. If you bought cardone 207879 it crosses to jeep part j3237193 for a 1981-1984 full size jeep (probably work). Both have metric fittings. They are both Saginaw GM pumps.

The original part number of 6 or 8 cylinder was J3251017. You need to get one compatible with this or adapt one, just be careful which high pressure fittings they have or you may need new custom hoses. The pipe you are pointing at can be removed, modified or turned once the nut is slackened. Will this cure your fitment issue?


So the pump is working fine but you bought a new one to cure a leak at the join with the high pressure line?

Are you not sure it is a leaking union? There are two types and a method for fixing. You could have a damaged flare in the hose if SAE or a worn o ring only if it is a rarer metric fitting..

This is your setup? All SAE flared fittings?

As you can see that return line is under little pressure and has some very ordinary hose clamps on it. If your only concern is rerouting and extending this line, it is not a big job.

hello
your original pump looks like it is a 82 and earlier. rockauto has them. if you still have the old can you can just swap the cans on the pumps. or rebuild the the original pump. its not all to hard. the hardest part would be getting the pulley off.

Hello Everyone

Thanks for the help! For those that are interested, it is leaking from the rightmost leak spot (between the fitting and the can) as indicated in Figure A of BagusJeep's first image.

Seeing as the new pump is not the correct pump, and I have not found a good replacement, I will be returning it and purchasing a seal kit to carefully install new seals on the old assembly. I will also be sure to check the hose fittings to ensure that they are the correct ones once it is all apart. Good thing I like a project!

Thanks for all the help.

I rebuilt my original pump with a seal kit from NAPA. Very easy to do and not difficult. Just pay attention to how it comes apart, especially the one way check valve.
