Bummer. From the numbering system described in the link Im betting thats an 001 series, or a related precursor before they beefed it up. They must have changed the gearbox at 002. Yours has a lighter duty gearbox and general build than the 002. That slip clutch is unrecognizable in comparison. I believe youre right that its a bearng, but maybe a bushing external to the gbox. Is it that large threaded portion that has the wobble? Does the stub shaft extending from it drive the blade? Is there a grease fitting?

Yes, the large threaded portion has the wobble, as matter of fact from the plate next to the gear box all the way to he end of shaft wobbles, but im pretty sure that is one piece. the large threaded portion is connected to the plate. Yes there is a grease fitting that screws in where the large threads are, had to take it off to back off the castle nut. Yes the end of the shaft you are looking at is keyed on one side and the yoke slips over it and a bolt holds it in place.

Bear with me here; if the pto drives the end of the shaft then the end does not drive the blades directly. The clutch has to act between there and the blades. If you turn that end does the blade turn positively. ... Or does that [ shaped piece of metal drive the blade.?
I am really intrigued with that jd bushog you have. I can find no representation of it anywhere. :confused2:

I can't find anything on it either. I think I'm gonna go to the john deere dealership tomorrow and blow some minds. The whole piece spins freely without the rest of the clutch assembly on it. A friend of mine who has bush hogged and farmed for living most of his life is confused as well. There is a number imprinted on the side of the gear box, w14795, still unable to find anything with that number. Oh and when I say it turns freely, it just spins on the shaft coming out of the gear box, the blades do not turn. Maybe there is some type of clip or ring holding it on that I can't see.

Odds are the bearing is out of the input shaft on the gearbox. I believe he L shaped bracket you are trying to remove is part of the shaft assembly. Take a look on the JD website for the parts catalog to see the breakdown.
The machine looks to be in nice enough shape that it is worth putting new bearings and seals in. It will also keep the gears in the proper mesh. You may need to add some shims to bring the gears back in alignment and take any end play out of the shaft.
