DC47 strip down and motor replacement
« on: January 10, 2018, 07:17:54 PM »
Have had the DC47 for a couple of years now and have found it very reliable... until the motor burnt out. I have to say this was probably not a design fault as when I investigated I found that the dust box was not only above the Max line but was completely full. I think otherwise I would have sent it back under guarantee.

Motors are available from eBay and probably elsewhere so I decided to have a go at replacement. It was not so easy, you can see the problems I had here https://manchestervacs.co.uk/DysonForum/index.php/topic,2971.0.html but I will, over the next few days, post a record of reassembly - in reverse order - to help anyone else who wants to do a motor replacement.

There are two sides to the ball, both of which are held on by plastic encapsulated nuts. The easiest is the filter side which is purple and has two cutouts to enable you to undo the nut. That one is easy.

The other side is the service side and is not meant to be user-accessible. You must insert a screwdriver and prise up the cap. Make sure you do not prise up the plate below which encapsulates the nut.

Next you need to remove the dust bowl and the small clear tube that engages with it. Then turn the vac upside down and remove the base plate held in place by 5 small screws.

Under the baseplate there is a spring loaded clip that centres the hose exit. This can safely be taken out without losing the springs, which are retained within it. This needs to be removed as one of the retaining screws is located underneath it.
