Review on 🌀 NuTone 5901A000 Blower Wheel Assembly: Superior Efficiency and Performance by Draven Invert

This is the third time in the last 10 years that this fan has had its motor shaft broken off. This appears to happen after dust and debris has built up on the fan blades, adding to the mass the fan must accelerate when it turns on. It will probably end up wearing out the flat spot in the plastic fan hole where it slides over the motor shaft. I was very excited to find this fan in stock without having to buy the entire motor assembly. The new fan fits snugly when properly aligned and slides in without tools. There was no locking mechanism in the kit to keep it on the motor shaft but luckily I foresaw everything in advance. Being addicted to RC airplanes, I decided to buy a 1/4 inch wheel fork with a set screw that tightens onto the motor shaft. I roughed up one side of the wheel fork and the plastic on the fan and JB weld glued the wheel hub to the fan (make sure the wheel hub is aligned so the set screw isn't on the flat part of the motor shaft and avoid the Place JB weld in hole where fan slides on motor shaft). After it hardened, I placed the fan onto the motor shaft and tightened the set screw. I hope this fan never fails again. Now I just have to remember to take it off and clean it about once a year.
