I don't think we should be looking at the cable as being the controlling factor, i.e., the thing that would fail first if the shear pin didn't. Fresh high-quality cable is much stronger than its rated working load. I suspect that on a winch with any sort of good cable, the housing will blow apart or the gears will strip out before the cable breaks. If we were designing this from calculated point of view, we'd start with the rated working load of the cable or the rating of the winch (8000 lbs, etc), whichever is lower, and work backwards from there to the shear pin. Personally, I would rather replace the shear pin at a load much less than the cable could probably take, rather than blow my winch housing apart or strip that big expensive brass gear.
