Review on πŸ”‹ Powerful and Durable Nutone Motor 8664RP Assembly 97017706: The Ultimate Replacement Solution by Terrance Castle

Revainrating 5 out of 5

Fits perfectly and fixes a design flaw in the original block

We have three Broan exhaust fans in our apartment for the bathrooms. All of them start to fail due to a design flaw. The plastic fan is only attached to the motor shaft with a press fit - it is simply pressed onto the shaft. After 20 years of stopping and starting, the fit loosens, allowing the fan to slide down the shaft and hit the case. You know your device has failed when you hear the fan banging against something every few seconds. This replacement part solves this problem by cutting splines into the motor shaft for a much tighter and more secure fit. The part fits perfectly and is very easy to replace - remove the electrical connectors and one screw, replace the old fan assembly with the new one. one, replace the screw and reconnect the part. It came just two days after I ordered it. The only downside is that this part is now made in China like everything else.

Pros
  • shank 1/4" x 1"; rotation = counterclockwise; 3.3 inch motor
Cons
  • Very expensive
