Hi Folks,
I just acquired a MF180, and noticed during my haying that I have a leak coming out of the top of the Orbital Steering Motor. I have been looking for a new one and have not been able to find one. Can anyone point me to where I can or is there a newer model that I could use?
Thanks!

As ptfarmer mentioned, there are two steering motors used. Early had Saginaw, and the kit is 835 866 M92. Later tractors after 645004620 used Char-lynn motors, that took seal 195 908 M1, 833 460 M1 quad ring, and cover O ring 831 907 M1 to reseal the top. Also check the hose/line connections, they may be leaks there too.
 
(quoted from post at 11:34:31 06/23/16) Is it gas, or diesel? also what is the serial number on the tractor. There is some alternative steering motors in the parts catalog.

513017M91 Pump Assembly, Hydrostatic (Char-Lynn #5795-3)

The whole pump assembly usually isn't cheap.

I would do like Dieseltech said, get.
195908M1 Seal, Oil (1 X 1-1/4 X 9/64")
833460M1 Seal, Quad Ring (1-1/16 X 1-5/16 X 5/64")
831907M1 "O" Ring (1-3/4" I.D. X 3/32")

You maybe able to find the seals at a bearing house, or a hydraulic shop using the dimensions.

Thanks,
I guess I may be not looking in the correct spot, all the ones I see when I searched for that pump Assembly had only 2 ports, mine has 4 hydraulic connections on the side.
