I was trying to figure out what to do with my hydraulic transmission fluid leaking out of the side of transmission reservoir case.

Everything was working fine on the hydraulics it's just there was this leak.

Couldn't imagine it would take much more than replacing a seal, but where to find the part number?

So where did I start, why the library of course! lol. Still researching (IE: digging ;-).

Which brings me here to the forum...searching for tutorial replacing seals on left side tractor transmission where arm exits case, right above foot rest.

Gonna havta get a photo posted so's we all on same page. 😀

Welcome to the fray.
If it is what I believe it is, RTV is your friend and then Permatex #2 on the bolt threads.
