THis is not the load shaft this is what I think is called the rockshaft arm. It leaks and runs down tractor and drips on ground by the sump screen. Is this a seal leaking and what is the best way to pull that arm off. Thanks. [Reply]   [No Email]

I wonder what is the best way to pull that arm off. Thanks   [Reply]  [No Email]

Be nice to put a bore camera into the bung hole plug and take a look...It's just very odd that it's leaking there...not doubting what your seeing...   [Reply]  [No Email]

THe leak has gotten pretty bad throughout the summer and is now making a mess. I also have a roll guard on the tractor and it looks like it could be in the way if the arm has to come off very far.   [Reply]  [No Email]
