BEFORE YOU DO THIS MAKE SURE YOUR DYSON IS DISCONNECTED FROM THE MAINS THAT MEANS UPLUGGED!!!!!! FORM THE SOCKET. The Motor on the Upright DC07 can be easily removed, Once you have removed the plastic cowlings that make up the brush housing and foot plate you should be left with the motor in a black plastic housing, with a grey end cover where air is drawn in. Now you need a bit of slack on the power cable that feeds the motor. To do this you need to remove the dyson on/off switch housing located above where the collecting bin sits. Once you have done this disconnect the motor feed cable from the mains side and then withdraw the cable to the motor out through the back of the switch housing. The motor in its housing can now be free'd from the dyson and you can hold is more comfortably. The Grey end cover can now be prized prised off with a flat bladed screwdriver. Once this grey cover is removed you are faced with a black rubber "cone" shaped cover/housing/damper that is attached to the motor. Hold the out black housing securely with one hand (our get some one to help you) and then pull on the rubber and working it from side to side. Although this can me quite a pull the motor WILL come out. This rubber fitting can then be removed from the motor if required. To put the motor back, make sure it is in the correct position with relation to the openning at the other end of the housing where the motor spindle pertrudes, then apply firm pressure to the rubber housing and push the motor back in. Avoid applying pressure to the central area of the rubber (the cone are) as it is possible to damage the centre of the motor housing, where you can see in to the fan and the fan retaining nut, if you do damage this it will cause the housing to foul the rotation of he fan. If this happens the remove the motor again, remove the rubber and gently prise the centre of the housing off of the fan (be Carfull) Hope this helps Anyone out there that needs it.
