About a year ago when I hooked up my hydro-assist it was powered with the stock 4.0 pump which I found to be quite inadequite. Due to the lack of higher flow from it, the ram hindered the steering responsiveness more than help it. So I removed the ram until I could address the setup again. Recently I had some time and was able to look further into the pump issue. I removed the pump and a/c compressor, along with the bracket that bolts to the head and shipped the pump, pulley, and bracket off to PSC for some fitting.

What Kelvin at PSC came up with was pretty impressive. He retrofitted a CB series pump to the stock bracket. The new pump is of the same basic design as the stock pump, just bigger! Because of the increased size, it is MUCH more productive: 1600 PSI and 3.5 GPM (Gallons Per Minute) vs. the stock pump, 1400 PSI and 2.6 GPM, roughy. After installing the new pump, plumbing the system and bleeding it, all I can say it DAMN, the difference is night and day! The steering has not felt this smooth since I had rack-and-pinion. Anyhow, 'nuff of me.. here's a couple pics. Will get more of the complete system installed when possible.

Sorry for the shotty pics, only had my cell phone to use..



^^ Back side of bracket, pump. Notice where the top right edge of the opening of the center portion of the bracket required slight clearancing for the feed line of the pump. The only other difference is the 9pm and 3pm holes on the pump are through-bolts; the only stock bolt used is the top/12pm Noon position.




^^ Front of bracket, pump and pulley.




^^ And the blingin' reservoir..

 

That's some serious bling.

No new pics of the truck?

 

Nice man! that is a huge increase in flow! I will have to do the same when the 5.4 goes in.

 

Awesome! But where are the pictures of the truck?

oh, and i think you got this in the wrong section.

 

Ok I called and talked to Kelvin.

Kevin I hope you dont mind me posting some of this.

roughly $450 for that pump and bracket modifications. comes with pump, pulley, reservoir, lines and fittings for a yota box.

cost is 205 to have the yota box ported for cylinder assist, they rebuild the box at that time too.

cylinder assists are around 180 with the hardward.

hoses are another $63 to the cylinder assist.

So if you have a SAS'd truck and want this the total is going to be around $900

 

I am going to Sticky this thread so it doesnt get lost.

 

It's all good Zach. I'm glad you could talk to Kelvin and get the info down in this type of format.

The only thing I noticed you didn't mention is a fluid cooler of some sort. I went with one Trail Gear offers: Trail-Gear Hydraulic Steering Pump Kit, Hydro Power (bottom of page), http://www.trail-gear.com/images/2007-0120-500.jpg. Runs about $80

 

Kevin,

I am working on combining this with my steering shaft thread. So any other details you have would be awesome.
