Is the 1-3/4 OD to the the actual shaft or to the outside of the weld?
A: 1.75" is the main coupler o.d. Across the weld it's closer to 1.850 as long as the welds are consistent.

7/8 KEY X 1 3/8 6T SPLINE F/F PTO COUPLER ITEM NUMBER: 1-1655 can you tell me what the measuremnt is of the hole on the key side, because i need a hole from 21 mm , and can i drill it because i need a hole in the key side for fixing it with a bolt instead of a key
A: The keyed side is .875", or 22.225 mm. There is a setscrew on both the PTO side and centered on the keyway of the keyed side. The coupler is machinable and weldable.
