Cub 125 relief valve replacement
 

Hey guys after Christmas I’m splitting my 125 because I have to repair the trunnion. I’ve found several videos and it doesn’t seem that bad of a job. Side note, I didn’t know that Sundstrand 15 is also in bigger Cubs. Anyway, I’m replacing the relief valves just because the tractor will be split and it’s convenient. My question is this: can I replace my manual valves with the automatic ones?

Yes, direct replacement.

Or save some money and send them to Mark and have them rebuilt. The info is in Sam's #2 post. But if you're wanting the auto release ones new, than LJ Fluid is the place.

Thanks for the info guys, I’ll send them off to him for a rebuild.
