I run the pump and box from PSC (not poison spyder). I couldn't be more impressed with it. Even with the Jeep in low, an infant could turn the wheel with one finger its so light. If you stall while you have pressure on the steering, watch out!! That wheel will snap back with a vengeance. Their site is www.offroadsteering.com. I was told by several people that the AGR pumps were OK, and prone to leaking. I heard no first hand accounts tho. If you go on pirate, everyone runs the one from PSC. Next time we're both on the same trail, you're welcome to give my steering a try. |

I don't think they offer a replacement level one. They do offer two levels of pump. Due to your application though, I'm sure you'll end up with the same pump me and matt have, the "extreme" one, due to tire size, locker, etc.

Bob, what is wrong with your pump? If it's not badly broken it can be modified to work very well, cheaply. I did Rich's pump to compensate for his larger tires and it works great. You'll also want to run a cooler. HEAT, #1 killer of P/S pumps, even stock ones. Plus, increases fluid volume. Let me know what you want to do.

If the pump is noisy, then some of the vanes in the pump are stuck. This allows the pressure to only partially build, Thus the groan and lack of assist. Most likely the rotor housing is scored or overheated and you may need a complete pump or a doaner pump. Are you comfortable tearing into your pump? If so I can give you more info on the procedure.

Bob, I'll give you the steps to modify your pump for higher pressure and volume. The goal is to build volume. With increased volume comes decreased pressure. So the pressure needs to be increased as well. You will need to remove the outlet fitting, this is the fitting that the pressure hose attaches to. Inside you will find a flow control valve and a coil spring. The flow control valve has a hex nut with a screen on one end, under the nut are shims. You may have no shims or up to, two shims. Remove the nut, inside you will find a TEE, a spring and a ball bearing. These stay as is. Remove the shims and reassemble the flow control valve. Next take the outlet fitting and drill the center hole(venturi) to .250. Locate the hole on the bottom side of the fitting (by-pass orifice), it should measure under .1250" stock. You need to drill this to .140". You will also find a small hole in the side half way up the fitting, this is the control orifice. The control orifice measures .0625" some are smaller .050". If yours measures .050" drill it to .0625" NO LARGER. Before you reassemble the regulator you need to place a washer in the bottom of the bore. .0625" thick and the same O.D. as the spring. Then install the spring, the flow control valve and the outlet fitting. Make sure all of you drill chips are cleaned from the components. The pump needs to be super clean and fee of debris to work properly. USE POWER STEERING FLUID, NOT ATF. There is a difference, atf is good for an old leaking, noisy pump. P/S fluid will help keep the pump cool and properly lubricated. Your end results will only be as good as as the quality of you pump to start with. Make sure and bleed the air from the system. Raise the front wheels off the ground and turn them lock to lock with the engine OFF. Do this a few times, then re check the level. Make sure not to over fill, keep it to the cold fill mark no higher. Then start the engine with the wheels still off the ground, cycle the steering lock to lock again slowly until the pump stops groaning and the fluid is clear. Recheck you level, only fill it to the hot full mark after you have driven the vehicle and the fluid is truely hot.  ?? |
