I have an implement end PTO shaft (old bush hog mower) that is seized and/or rusted on. I don't have a torch set and was considering a Mapp torch sold at Lowes. A few questions:
1. Will one of these torches get the u-joint hot enough to do any good?
2. Assume it will, is the method heat and beat - should I get the u-joint hot, then tap on the wings to start the slide-off process?
3. Is there a non-heat method I might try?
I need to replace the front u-joint coupler and that will be $140 (old-odd size according to the local u-joint shop), so I'm thinking a new shaft would be better. I am also concerned that the shear bolt is pretty useless at this point and I don't want to damage my new tractor.
Thanks,
