Hydro-assist steering?

Does anyone know anything about drilling into the C-11 steering box for the high/low pressure lines to creat hydro assist?
Anyone have any detail diagrams of where to drill? (PLC7.3, thanks for those emails, they helped, but now I need a more detailed drawing)

What are the weak spots of a C-11?

Any help, thanks...

Raw Power checkout the PS pump for Hydra boost system it comes with two pressure lines and one return, may be it can modified to fit your needs.

what does hydro assist mean? i thought all ford diesels had power steering...? or is that not what you are talking about? i have had to drive my ford a couple times with no power steering and it really sucked. i couldn't imaging it all the time. or are you talking about the brake booster?? cuz i hooked up a hydro booster on my truck and it hooked right up, plug-n-play. 30 mins.

Hydro Assist is a system that runs a hydraulic mounted to your axle and tie rod. It has two ports, one for left turns and one for right turns. You drill into the PS gearbox for the Low pressure and High pressure ports (which vary-"Port A" is high pressure when turning right and low pressure when turning left, and "Port B" is opposite of "A"). This set-up still maintains the mechanical linkage between steering box and the tierod in case of failure, but also provides much greater power when turning and little to no stress on the frame around the gearbox mounting points. In order to do this you have to remove the gearbox and strip it completely and then drill two holes in it for the two lines. It acts as a steering stabilizer as well. This set-up is streetlegal, unlike full-hydraulic steering(no pitman arm, tierod, or any mechanical linkage).

mount a hydraulic pump on the pto and use one of those valve assemblies like on maintainers or something on your steering driveshaft. or like the ones on those center pivot loaders.

Its easier just to drill two holes into the gearbox and run a line from each to opposite sides of the hydraulic. I just need to know where to drill...
