It will be pretty difficult to unbolt the gearbox while sitting on the aircraft, but I suppose it can be done. ;-) Sorry. Couldn't help it. I know you can inspect the seal by just pulling the gearbox off, a very simple procedure. However I don't know whether you can change it.

You have to split the crankcase to get the crank seals in and out. They have teats on them that rides in grooves in the crankcase halves so (thankfully) there's no way they can be removed or installed without splitting the halves. When you do install the new ones, be sure the little teats don't cover up the flow holes in the halves. i.e. orient the seals and them mark where they are with a marker. Then check the alignment of the marks once you close the crankcase.

I didn't think I'd get away that easily. If the crank seals are leaking, i.e. the runny fluid is coming out pretty steadily, you're better off doing a full teardown/cleanup/reseal. By the time you get the crankcase apart, the whole engine is generally apart anyway...... Might as well do a full service at the time....

I just have a little bit leaner mixture on the front cylinder and wonder if it might be sucking a little extra air. The crankcase itself appears absolutely water tight and there are no visible leaks whatsoever.
