I've been noticing a decent leak of power steering fluid for a while now, especially after turning it off. Just recently, I noticed it seemed to do it only when the wheels had been left turned to the left. If the wheels were right of center, no leak.

Anyway, I just put a new seal and o-rings in the front end of the pump and when I turned it off this time, the fluid came spitting out the top of the reservoir until I loosened the cap.

I'm guessing this is a sign of a blown seal in the box?

Both the pump and the box are AGR units (a super box2 and a TC style pump.) I've had terrible customer service and product problems with AGR in the past and I'm hoping there's an alternative to sending the box down to AGR and paying them to rebuild it. Anyone got any suggestions?

Rebuild it your self - you just have a standard ps system right - try dropping the reservior level a little bit (is the fluid that is overflowing aerated or just clear ps fluid/)

I think the general consensus is that the AGR stuff is just a re-badged J-20 large bore box - the rebuild kit for my standard box was about $46 and came with everything including new bearings - I can give you a hand if you like (done 3 so far :rolleyes: ) Perhaps Matt Hodges of West Texas Off-road -("The lakerat" - IIRC) has some more info if they (ARG) changed the internals of the box much....

Basically I would blead the system really well before I went screwing with the box - trapped air will be pressurized by the pump during operation and then expand forcing fluid up and out when the pump goes to 0 psi - if the fluid you are finding is aerate you may look at the pump as a source of injecting air into the system...

Well, I just went out and bought a replacement box since one of my mounting ears was broken off as well.

I hope the problem isn't with the pump at this point as it may blow the new box.

Where is the check valve in this system anyway? box? or pump?

Jay

It is just air in the system. Once it gets bled out it will stop.

There should be a spring and plate style check valve on the pressure bung of the box - injecting air into the system will not really harm much but the performance - unless you are really running enough air to make some things dry out and not recieve lube - (your assist should be gone long before this)...
