adding power steering question

Definately needed if it's not too much trouble ? Thanks , Keith

AWSOME !! The tape measure is the trick !! OK I have arms,the linkage length (lift arms ceter to center and actuator arm(side the link pulls on to lift the arms) would finish off my questions ;-) Thanks Leaguedude your a life saver(well a trial and era saver is more like it

Hi Joe, what length cylinder did you use for your p/s ?

The cylinder I used had to long of a stroke. So I modified it to have approximate 5 inch throw.

Down the road I will change the cylinder to a smaller bore cylinder.

I was thinking of doing something similar to that, I was going to put power steering onto a JD317. I was looking at the breakdown of the 318 power steering hook ups, & found out that 2 of the ports go to a cooling unit for the hydraulic fluid.

I believe is can be done using the return line tom run through a cooler. If I can find a small cooler someday I will do it that way.

Wow... after reading how complicated and expensive a power steering system is I am so demotivated to do this ! I was hoping to just run the system off of the hydro tranny but that sounds like a bad idea now too :-\ What should I look for for a used valve? Is there a specific type of steering valve that would be easiest to setup?

You can use the return line from the transaxle to operate the power steering. Provided your using a open center steering valve. They can be bought used for about $125.00 to $150.00 from ebay. BUT, you have to hope that the top seal does not leak. They do not just sell the seal, you have to buy the complete kit for about $80.00. Hopefully if you buy one it will not leak.

The steering column out of the john Deere tractors, or Simplicity tractors are basically the same. Just as long as they are open centered they will work. You just might lose a little power to the transaxle while your steering, but not much. You have to remember the Eaton11 pump needs to be kept primed to have power. That is the way it is designed.

Even if you find used parts, it will cost about $300.00 to $400.00 between steering valve, cylinder, hydraulic lines.

But well worth the time and money

Jordan , you can buy a brand new steering valve for $149 from Surplus Center and a 1x6" cylinder for like $89, less than $250 for the main components. But hoses can get $$$$ . Don't give up , it only takes time and patients and a little $.

Do you have a link to this steering valve. Would like to look at it.

also a 1x6 cylinder may not work well.

Your right Joe , the cylinder might need to be limited, but that extra 1/2 inch of stroke might make it , I took off the steering link from the box and was able to get almost an extra 1" travel in each direction at the spindle before it hit the stops, but if you didn't want to limit the cylinder, just make the spindle arm a touch longer, this would help in a multitude of ways too.
The steering valve has a "powerbeyond circuit built in so it can feed your hyd.valve after the fact.
