I nosed into that Dyson motor, just curious, while in there for just a
clutch problem. That has a plastic retaining ring around the fan end held by
4 wedge clips, 2 screwdriver job to part. Large rubber boot then pulls off
and motor is "floating" between that rubber and a rubber disc at the drive
axle end , pierced by 2 locating dogs to the casing. So no mechanical
vibration transmission from motor to outside casing
