When fitting the 10-4-12, the square bore interface requires the PTO shaft to have a matching square profile at 0.875". There is no keyway — torque transmission is achieved entirely through the square bore geometry. Confirm the shaft measures 0.875" across flats before ordering.

Square bore PTO yokes like the 10-4-12 are common on European tractor PTO shafts and certain implement gearboxes. The 1000 series with a 2.50" CJ-to-end is a standard geometry. Verify the 0.875" square bore dimension precisely, as square bore yokes are not interchangeable with round or splined configurations.
