I had no idea what I was doing, but good neighbor George told me the belt could be replaced without calling any service company. I ordered this based on the specs the website provided, and it works!
The price was about $10 less than the Sears website and a couple others I tried, and the shipping was reasonable, if a little high.
Hopefully this belt will last 10+ years like the last one, but if yours doesn't, you could probably do worse that Wayne Dalton.
