Old motor is Emerson K55HXHSF-8846 with 3 wires (black to DP2 loaction on board, Orange to cap. and blue to cap.
New Dayton 4M226J motor has 4 wires (Black, Brown/white, brown, and purple) Per plate on motor for three wire connection it says insulate brown/white wire, brown wire to cap., purple wire to cap. and L1, black to L2.
Can you help me clarify where to hook up the 4 wires in comparison to where the 3 wires were?
You don't use the brown with white strip. You wire nut it off(insulate it) so it can't short to anything. Then connect the purple to one side of the new capacitor, and the brown wire to the other side of the new capacitor. And connect the black wire to the DP2 on the board. The third wire that was on the old capacitor gets connected to either terminal on the new capacitor. If the motor spins the wrong way, move that wire to the other terminal.
