This motor was an exact fit for the original. As others had reported it is slightly quieter as well. I was able to perform the installation myself and probably saved a bundle. It's been installed for several months and is used 1-2 x a week, at least once throughout the house. I would buy this again. The only potential drawback is the chrome exhaust extention I had to use my original and drill a new pilot hole for the retaining screw. Keep all parts from your previous motor until the new one is installed! You won't be disappointed.
