Yes, both of my yokes were tapped above the key. Odd thing was the sprocket end was drilled and tapped 3/8"-16. The on at the gearbox was 1/4"-20?
I no longer have any shear pins, that are holding torque. I keyed both end, gearbox and sprocket. Lots of red Loctite.
It's snowing here now, I'll put it to the test tomorrow.
