The pump still bolted to my xj was set up for more pressure.

I made a socket.

Its spring was slightly longer it also didn't have the small washer.

I drilled passage to 5/32 and cleaned the screen.

It might be temporary but it now steers great again

Re: Modded steering pump.

Think this is the first I've seen of this mod. Got any links to share for more reading?

Curious if an underdrive pulley would help

Suposebly it does help theres mention of smaller pulleys on pirate but I didnt find any though I didnt put much time into it.

I did take the electric fan off the parts jeep and wired it into my jeeps factory wires. Supringly the dam thing turned itself on. It appears it may actually help cool the power steering pump.

Do all xjs have electric fans?

Re: Modded steering pump.

I doubt the early V-6 years had electric.

I don't know about the Renix years, but my guess is yes.

I am fairly certain all the H.O. years do.

Was kinda amazed it worked had to cut the harness out of the parts jeep and wired in to to unused wires on my jeep popped tge hood after a long climb and fan was running.

Re: Modded steering pump.

Yes Renix jeeps have an electric fan.

You took apart a power steering pump from your parts jeep to replace the one you have that is dyeing? Most people replace the power steering pump with one from a Grand Cherokee. There was a discussion about drilling out the fitting and apparently it is not advised as it can lead to cavitation. I think 5/32 is the exact size someone mentions as being okay to drill out to.

I havent replaced it. Took apart the pump out of my mock up jeep to learn. I guess I learned something.

Did the mods to the pump in my jeep and cleaned.
It makes a whine at 2500rpm and above but not bad I have drilled the port over the recommended size now. Maybe cavitation.

Not to shabby going from being almost unable to steer to light easy steering on the trail for free.

When this modded pump decides to go ill do the v8 grand pump. Probly take it apart first to see if its any different than these two pumps ive already taken apart. So far both the ones I've seen inside where set up for different pressure

Modded steering pump.

This thing sits under that fitting it rides on a spring remove the washer or washers. Removing washers is supposed to put the pump at its max 1400 psi or so.

Theres a check ball in there dont lose it.
