Hi all. The tractor in question is a Case 1490. Issue is the steering motor sits right below the steering wheel and it leaks fluid right on my shoes. It's getting annoying and rather slippery. I did post on the Case forum BTW. Fellow over there said it could be a seal in the orbit motor? Been thirty years since he done one. Would have to pull the dash probably but doesn't look to bad to get to. These motors sell for around $500 new aftermarket. I have been reading a lot and it seems many modern tractors use steering motors so was wondering if it is a DYI project to rebuild a steering motor in general or does one take it off and take to a hydraulic shop, or replace new?

It's a steering VALVE, not a "motor", about $1500 from FIAT, YIKES!
I don't see a kit on the on-line parts lookup site, but there's a reference to it being and "OPS 125 Orbitrol" which would make it a CharLynn, now part of Eaton, and parts should be available from a good hydraulic parts supplier.
Not TOO tough to "kit" as long as basic instructions are followed, there's parts that have to b "timed".

I had a 1490 years ago, and when I got it there was a problem with that orbital motor. The dealer that I bought it from fixed it. I removed it, it was not too bad a job, took it to them and they took it apart and fixed it. They said that tolerances were extremely tight requiring heating the body and cooling the rotating assembly, in order to get it back together.
Hey showcrop do you remember any more about the job, hours, special tools, how many hydraulic lines and did you cap them or something to stop constant leaking while it was out? What you say about them cooling and heating it might make it worth just replacing the damn thing. I'm almost certain they can be had on ebay for around $500.

I know that I didn't use any special tools. I didn't really have a lot of tools back then. I remember that it was tight in there to remove the hoses. I remember that I labeled the lines in order to be sure that I got them back in the right positions. I didn't plug the hoses. You will not get much oil out of them. I did cover them, probably with tape to keep any dirt from falling into the open ends.
