I used the lift cylinder and valve from a Ford GT on my Craftsman GT-18 and the stroke was the perfect length. The CC cylinder was too long.

Thanks guys. I have an extra valve and cylinder on an Eaton 11/Peerless, so that will handle that part. I have a GM style power steering pump to supply the pressure for it. Just have to have time & weather to make it all work.

Are you putting the cylinder under the tractor or back by the hitch?

I'll bet you can make it work.  :D

If you decide to put it on the back let me know and I will send some photos that might give you some ideas.

Your going to be surprised at how hot that power steering pump gets if you use the lift a lot. I cycled mine quite a few times in a row when setting it up and darned near burned my hand on the pump reservoir. Did some checking and it sounds like 250degrs isn't that uncommon on one of these pumps. I've already located a cooler if it gets too hot while tilling.

Looking forward to seeing your project completed.

It'll be a while yet, especially with winter coming. I want to keep it located where the lift was before as I have a tiller for this. It's the only implement I have for it.

250° Holy way too hot batman!! They don't run that hot in a car so something isn't right? I ran a gm pump on my old moto-mower with a center grader blade for grooming my RC racetrack and it never got over 110° ? And it had a small plastic reservoir on it. If the oil gets hot quickly you have a restriction some place causing the excessive heat. On the GM pumps this can happen if the wrong fitting is screwed into the pump. Or the flow/relief valve is stuck ( the fitting you attach your HP hose to is part of this unit). So if at all possible use a factory hose end in the pump, yeah yeah, its hard to get right! Well if you have a good hydraulic hose house, they can cut the steel pipe and you can then use the proper "bite tite" fitting on the end of your hose or have them flare and install a female JIC #6 flare but to the pipe. Proper and easy Peasy!.

The pump I will be using is off a 4.3 that was in a boat. Has hoses already hooked to it that I hope to reuse!

My pump is out of a Nissan 280Z as I wanted one with a metal reservoir. I would have preferred an old Eaton power steering pump as I have had excellent results with them in the past. If you can find one of those from a truck they have a large oil reservoir. 

  The time it got that hot I was running the control valves part way open a lot. Making the cylinder move very slowly as I was setting up the lift linkage. It has not gotten that hot again. They do make power steering fluid coolers so it does happen.

As far as I know, all power steering systems use a cooler of some sort (at least on cars). Some cars (in my experience Ford) just make the power steering lines longer so that the fluid can cool before going back to the reservoir. This way the system does not need an acual cooler and the cost of a cooler can be eliminated.

This has the metal reservoir, basically the same pump GM used for many years. If need be, a cooler will get plumbed in.

Long metal lines would have been the best option. Unfortunately the local shop does not have the ability to fab those so I ended up with hoses. The other issue is on an automobile going down the road there is a lot of air flow but on a GT there is little or none.
