Watched the video and ordered the part which arrived promptly. Repair took about 15 minutes with a Phillips screwdriver, a ratchet, and 2 sockets. Unplugged the machine, removed the back cover, removed the 17mm bolt from the rotor - then pulled off the rotor, removed 2 wire retaining screws and the ground wire, removed the 6 10mm bolts from the stator and laid the stator down, unplugged the rotor position switch and unclipped the switch from the stator. Snapped the new switch to the stator, plugged in the harness to the switch, and reassembled in reverse order.
