An excellent video but I have a question a tip and a note. First the tip, in the video the fan case seal is not pushed over the lip of the motor fully. If you do this properly there's no need for the fairy liquid. The edge of the rubber has a 'U' shaped edge which should fit over the metal. My note is that the exact construction does vary. On my model the motor retainer has four plastic lugs which need to be pushed in whilst levering it out otherwise you would break them. Also on my one (never been taken apart before), the belt guard had no metal clip and the rubber part had a wide and a narrow lug so has to be fitted the right way round. My question is how do you refit the clutch assembly and its casing. The casing has three torx screws and a long metal dowel to secure it and I had to remove it and the motor at the same time and not sure what order to put it back together.
