Rated 4.0 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Worked beautifully I checked out the motor online, went to the nearest Home Depot and purchased it. The only issue I had was due to my own oversight in reattaching the motor bracket. One end of the bracket was slightly longer than the other which caused slight misalignment of the belt pulley. Other than that the install was flawless and motor improved the flow from previous lower horsepower motor. Very happy with the product. June 10, 2012
Rated 4.0 out of 5.0 by Simple install with quiet motor My old motor must have been 12 years old (or worse) and it finally gave up the ghost. I'm not afraid to try small do it yourself projects so I figured I could handle this one. With the easy clip mounts and the nicely matched equipment I had it installed in 45 minutes of work. The old pulley was impossible to remove from the old motor shaft so I had to get one from a local hardware store. That too went really smooth. Once it was installed we found the new motor much quieter than the previous one. I guess it had been on its death bed for a while. July 16, 2013
Rated 5.0 out of 5.0 by Plug and Play Really hot Sunday afternoon and had to run to HD for a new swamp cooler motor. In stock. Easy install... lined right up with our motor brackets even though the cooler came from somewhere else. Back in business within a couple of hours after transferring the cord and belt pulley.

Rated 2.0 out of 5.0 by Doesn't fit! I bought the motor in the store where I carefully matched up the spec's. One spec I didn't check was the length and circumference. It says it installs quickly...it still is not installed. The standard mounting bracket will not fit this motor as the motor is longer and larger. I returned to the store to see if there is a bracket that fits this motor and there is not. The only bracket they sell is the same as my original. So now I need to see if I can find a bracket to fit 'somewhere else' or return the motor and look elsewhere. Good luck, frustrating to say the least. June 3, 2012
Rated 4.0 out of 5.0 by cooler motor was thought out better than the previous one. The previous motor was maintained by periodically re-oil the bearings. The new one has no need for re-oiling. September 11, 2012
