Ok looking at doing a full hydraulic setup. I have a D44 that I will be putting it on. I was going to upgrade to the four bolt power steering box from a 78-79 but I figured why not full hydraulic. It is a 74 F150 that's going to end up a full mud truck. But I was looking at tractor supply and I should be able to get most parts from there. I didn't see an orbital valve of any kinda. And also can I use my stock power steering pump. It is from this year truck with the ram assist. Has a high pressure line from the center of the pump and a low pressure return. Just trying to figure out what has ben done before, what works and what will I need.

 

Depending on your budget you could either get a brand new orbital from psc steering or start searching junkyards for combines/forklifts or any other type of equipment that has hydro steering, but before you yank the orbital out look at what type of pump the equipment has. Some machines run a pressure compensating pump that has its own bypass at the pump itself so if you use that type of orbital you will go through stock power steering pumps like a fat kid goes through candy.

The rest of the pieces to the puzzle can be found at tractor supply/auto parts stores such as lines/fittings.


In my random internet searches i found this, pricey but no searching required. http://mad4wd.com/index.php?main_page=index&cPath=59
