need help w/ rockshaft + hydraulics
 

I am making an attempt at building a 189 from an 1860 frame and engine. I have all of the sheet metal mostly fitted, nothing completly attached but so far it looks as if it will all work. I have a few questions about fit on some areas.
1) Of course the 1860 didn't have hydraulic lift.
I looked at the parts for an 1862 and a 2082. The lift cylinder is the same on all of the supers and cyclops so that is one problem solved. The one I am stumped on is the rockshaft. The part #s are different on these but would any one of them work ok. Why would the rockshaft be different between the supers and the regular cyclops GT? below are copies of the parts sheet.

2) I am entertaining the idea of using super tires and rims. What would I have to do to get the room I need under the fenders? Could I just put in spacers to raise it an inch or two? If so, I would have to space everything, tunnel cover, tower, front grille. What are your thoughts on this? Could I get away with 24x12x12 without the lifted fenders? And I am not sure about the front rims. What size are they on a super? (I just sold my 982 today and this idea came after it was gone so I can't just go measure one)

I guess I'll go ahead and post some pictures. I was hesitant to post these but I will just in case it will help you figure out some things I may need to do. You may ask, Why would he do this? Well, I love my 149 and always wanted a 169. I bought this 1860 mainly for the front axle but it ran so good I wanted to use the engine in an 1872 if I could find one. I got to looking at it and the 149 parts tractor I have and started measuring and then before you know it I had the fender off and the fuel tank pulled. The fender pan fit so I kept going. I liked the hydro lever on the right side of the steering wheel so I am leaving that and the throtle in the same area. I will have to make a custom dash cover (aluminum) to match this new stuff.
I may be able to pull this off and maybe not but it is my first attempt at a custom build.
Notice in the pictures, the tower was a good bit taller than the one from the 149.

The super rockshaft would fit in the frame but wouldn't lift any front mounted implements correctly. Any 82 series GT rockshaft and cylinder will work.

Thanks Matt, would the GT rockshaft operate a cat 0 hitch? How about the tire fitment I talked about? How would you address this issue?

I have a rockshaft from a 1863 (cyclopes) I would be willing to part with. It is out and disassembled. It has the (bushing caps ?) for were it goes through the frame also. All you really need to do to fit the 26x12x12's is space the fender pan up a little. Or find a super battery box, They are taller.

Yes, it will. It would probably be easiest to just space up the fenders with some 1" square tubing or something if you are going to put larger tires on it.

If you run an 82 series set up it will have plenty or power to use a cat-0 set up. I knocked the left side rockshaft bushing loose a while back, I welded it back up along with the lock out nut that had fell off when I installed it in the begining. I forgot to pull the lockout bolt back out when I mowed and I tore the depth stop knob off when I ran the deck down!

As far as the tires, I spaced my fenders with 3 standard washers per fender bolt, which gave me about 3/4" between the fender and top of the 26x12x12's..

I will add another idea if you run an 82 series lift, and that is ditch the spirol pins in the rockshaft with grade 5 or 8 bolts and nylon lock nuts. I took me 15 minutes to completely pull the rockshaft and lift back out to do repairs this last time..

I got some time yeterday to mount the 26x12x12 tires on my GT rims using two tire tools/spoons and a vice grip. They fit the tractor pretty good and one inch is all I will have to raise it. I don't have a set of supers yet and still entertaining the idea of making my own. I will have to raise everything to keep the original lines. I'll likely weld on a piece of 1" tubing to the top of the frame and grind it down to look like the frame is one piece and not cobbled together. I don't have any front wheels yet but I did turn the GT fronts around to make a wider stance just to see about what it would look like.

I'm mainly waiting until I can get all the hyraulic lift parts so I can fit them and see if I can use the 149's lift lever or if I will have to go with an 82 series lift handle. I now know that I need a rockshaft from an 82 series. Will the control valve from a 149 operate the lift cylinder from an 82 series or cylclops, if it will I know I can use the original lift lever.
I think I have a name for it, 189 micro super or 189 MS for whatever it's worth. Oh well, it's fun and a good way to learn about other tractors in the process.

Nice work, Chip! :High5:

You can hook the 149 valve to the 82 series cylinder. You may need custom-length hoses.

BTW, this project is REALLY cool. I never would have thought you could get the dash on the frame, and I think I might try something like this if I ever wind up with another cyclops parts tractor. I really like my 82 series tractors, but I also owned an 86, 108, and 2 128s at one time, so I'm also partial to that style.
