got a worn shaft & its coupling bushing that needs a slight build -up & re-machine. JB weld? or ? There's allot of choices now days.Its a hydrostatic trans coupling shaft end. The bushing had loosened up & wore the last 1/2"-3/4" of shaft & the ID of its bushing, on my 30yr old Ramsomes Bobcat (when they were still yellow) mower- I really do not want to take apart the hydrostatic trans to weld & re-machine it properly. So its shoe string time. It has a woodruff key that still makes contact with the steel shaft with a setscrew pushing on it from the bushing. Another setscrew at 90deg that I'll clear out the epoxy, so it makes contact with the steel shaft. Should hold for cutting my grass another 15yrs. I've seen machine re-builders use an epoxy called "turkite"? on worn dovetail ways, this is kinda the same thing.
