The tiller is a MF 4850 it came with the tractor when I bought it.I had to change the u-joints and yokes they were completely worn out.There wasn't any needle brgs left,of course it wasn't just a go and buy the joint repair only.Had to get different yokes as well.Had to cut them off and weld the new yokes on in place of the old.We all know that the factory joint were just tiny little ones' I ended up using weasler yokes series 600 I belive.Had to do some machining and welding and measuring to get them all set up properly.Larry

That is one awesome machine. :thumbs: I hope mine look that good when I am done. I would love to see more pictures of the power steering conversion. :thumbs:

I went out and took the gas tank out and the side cover off and took some pictures for you.The steering box is from a 1977 chev van.I had to do some adjustments of the frame to get the steering box to fit in the same spot where the original one was.I used a power steering pump from a Dodge D100.I also changed the front axle pivot point for the tie rods and drag links.I drilled straight down thru the center of the axle and welded in a pipe that was machined for bushings.So then I needed to change how the tie rods ends where connected to the pivot point as well.Same a with the top part of the axle pivot I had to make it so it would accept the tie rod comming from the steering box.I used automotive tie rod ends on both ends of the drag link comming from the steering box.This was done 10 yrs ago and hasn't failed yet.Oh yeah the pivot thru the axle is greaseable.Larry

Wow, interesting set up. I have never seen a power steering set up like that on a GT before. Does it work well? Thanks for ripping your tractor apart to get me the pictures.
I am going with a hydraulic power steering set on my 1855.

The charge pump powers the steering just fine, but DO get a 5 port steering valve/column for the power beyond for the hydraulic lift valves.

I already have the 5 port orbital and the cylinder. I just need to get hoses made up. I also need to figure out what hose goes where on the orbital?

Where did you you pick up the 5 port orbital from and whats it out of.Just in case I ever come across one it would be a simpler way of making power steering on say some other unit.?? Larry

I scored it on fleabay. Both the orbital and the steering cylinder came out of a JD420. They usually bring top dollar, but they are easy to work with. I will start a new thread with my 1855 project. If things start to warm up here, I will get working on that project again. After looking at your 1655, you have me motivated to get that thing running.
