• Long tooth is correct Turn nut clockwise to loosen. To hold the shaft of the shaft of the motor I used a pair of long nose pipe / multi grip pliers to squeeze the plastic impeller tight around the motor shaft while my partner loosened the nut with a socket on an extension bar cos I needed both hands to get max force to grip the shaft thru the plastic of the impeller. This is not a good design by Baumatic -There really should be a steel or liner or harder material in the drive socket of this impeller as the plastic is just too soft and will wear away around the keyway profile of the shaft. I 'll see how long the replacement lasts. By William McCooey - Belfast - 16 November 2014
• May I just verify, as the fan operates anti-clockwise To remove the impeller locking nut, you must unscrew it in a clockwise motion. By Longtooth - - 16 July 2014
• I had to break the collar off the old impeller to get it off Then this allowed me to undo the locking nut and replace the motors fan By Longtooth - - 16 July 2014

  It may be necessary to prevent the motor armature and shaft from turning when trying to undo the nut as holding the fan may not be doing this.
