Just received the parts to rebuild a rotary valve power steering unit.  If the topic exists, I apologize.

John,

I have read your PS conversions until my eyes have bled.  I've talked with D-17_Dave over the phone for hours.  This was definitely going to be the way I went.  I have the Ark 700 loader so without cutting the subframe, I'm going to potentially look for a different cylinder setup.  I'm talking with a guy currently in north central WI who has done this conversion as well as the Vega & the other GM PS steering box.  He is currently working on a PS that uses the Hydraguide rotary valve in conjunction with a push/pull cylinder that replaces the tie-rod.  I picked up the rotary valve & cylinder a couple weeks ago for this specifically but I'm not ready to notch my loader frame for the cylinder.  

Lloyd, I talked to MNOONAN as well & he put me in touch with the guy that has done about every PS conversion possible on these powermax tractors.  

There is such a thing as too much research.  

Thanks for the appreciation.  I owe that to you both for how much I've learned from reading your past posts.

I have given a push/pull cylinder arrangement a lot of thought and have not come up with a design. It would be the way to go. The Sunstar cylinder does not have quite enough throw to go full lock to lock. I can live with this, but I am always looking for a better way.

I do not have a clearance problem with my ARK 600 loader, I understand the issue with the ARK 700.

Keep us posted if you come up with a push/pull steering cylinder design.

Most new economy cars today use electrical power steering assist, to avoid the power (and fuel consumption) loss of driving the hydraulic steering pump. 

Electrical power steering is also common on UTVs (side-by-side ATVs) as either standard or optional equipment. It is also available as aftermarket kits such as this:

That looks to another great option.  

I have been fortunate not to have charging problems with the Onan in mine as of yet.  But I have noticed when both electric clutches are operating an the engine is not at full throttle, I do notice a draw on the ammeter.  I'm wondering if this would be more concerning with an electric PS unit.

This is what is great.  The longer I wait, the more options there are.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
