Steering Power Steering loss when clutch is engaged

[rfullington]

I have recently got my newly acquired 1980 CJ5 running pretty good. I am still working on the bugs I find as I drive it. I recently noticed when I am at a stop sign or the clutch is engaged, I have no power steering. (No comment from the non-power steering jeepers out there HAHA) If it did not have power steering, I would be okay with that, however, if it does have it and its not working as it should, I want to fix it in case it is an issue that might cause damage to any of the steering components.

Good questions, I should have added this information. The pump is one of the first things I replaced about a year ago. But it still wasn't drivable at that time. The fluid levels are fine and the belt is in good condition and seems pretty tight. There are no squeaking noises or anything out of the ordinary when you look and listen. Power Steering is great when clutch is engaged making a turn.

Does it pump if you increase the engine rpm?

YEs it does, I tried this morning to make sure. When sitting idle at a stop sign, clutch engaged there is no power steering, but if I increase the RPM the power steering works.

There is a flow control valve that the pressure line connects to on the back of the pump. Might be stuck. Hotrod guys that under drive the power steering pump have to modify the flow control valve. Might be worth some research on the valve.

How much did you have to increase the rpm?

Not much, I do not have an RPM gauge, but if I had to guess maybe 500 RPM...

Wonder if you could put a different pully on the pump to speed it up?

That's a pretty good idea Gary! I will start looking to see if I can find some slightly larger pulleys. Thank you!

You'd need a smaller pulley to make it go faster...
