I said I was all done with the Series III D10, but after running it hot, I found an oil leak. The top bushing on the governor is dripping oil out, not too much, but enough to make a mess of the front of the tractor if allowed to continue. What I'm wondering, is if those of you with late D10s, recognize this governor top bushing arrangement. The one with the nut on it and painted is the D10s. For comparison, I shot the same photo of the type I'm used to. I'm resistant to just swapping in one of my spares until I know if this nut being on there is someone's hack to shim it, the nut doesn't turn (I won't know how or why it's in there until I pull it off) or a different case than I've ever seen, something later. Just wondering if anyone's seen this nut arrangement.
BTW, Parts manual shows a normal Governor housing with no nut on it and what I probably should do, is just swap it with one of my spares.
