Some of the customers may experience some issue in installing this motor. One of our customer got it resolved by going some extra steps. As per him,

"The fan shroud on this motor is different from the one on the motor in the vacuum. I just removed the blower housing from the old motor and put it on the new one, and also moved over the board with all the wiring and hooked up the power leads to that board in the same postilions where the old wires were plugged in.

Just to be safe, I ran a sharpie around the edge of the blower housing on the new motor so I would be able to install the new housing correctly. All it takes is a large screwdriver, a hammer and some patience to move the blower housings. "

He has a Miele White Star. Hope this information is useful. Thanks to George for sharing this.
