The unit has a .75 inch shaft running in a 1.0 inch OD tube with little
clearance. The shear pin holes are/were .25 inch, but they're a little
worn now.
I got a suggestion that this may be part of the problem.. the worn holes.
I'd drill them out to the next US size: 5/16" if I had SOME idea what the
resulting torque at shear might be..

Any ideas???
