Because the switch is not repairable or available I bought the motor assembly...the new and improved version. The part came the next day that was amazing! But when I opened the box I was a bit startled - all the pics I took of the old wiring were no good, the motor wiring was totally different and all the old wires had to be cut and new connectors added. But the directions were very good along with provided pictures. One thing could be corrected - the new pin connectors are too big on the crimped end. The pin locations on the centrifugal switch are tight and it gets real crowded using the supplied connectors. The job went smoothly, I had it all back together - motor, wires, chain and pulley, and tested in an hour. Doing the repair myself I saved our budget over $550...that's what Sears repair service wanted to charge me!
