Thanks for the responses guys.
I have taken my DC04 apart today, just to get the motor out so I can get the numbering out as I was told that Dyson used 3 different types of motors for the DC04. I'm assuming that they mean the Dyson Lime one which has no brush control, the Zorb and of course the standard brush control DC04 I have. I will order the motor when I come back Middle East end of next week.
Anyway, I took out the motor, turned the spindle and noticed a slight rattle. The fans are not rotating!!! I'm not sure what has happened here as the motor turns ok and so does the nut at the back of the fan bit but the fan doesn't. It seems that when the motor burnt out it made something break in the unit as the fan did not just decide to break 7 years later. The motor has a funny smell to it and 2 - 3 communtator bits look scorched.
I agree it has does good in 7 years. The belts look in good order too on the clutch so will keep the same clutch, just replace the motor and the post motor filter which is completely black.
Id like to post a link to my Youtube video showing the noise the Dyson DC04 does but not sure if I can here so just search Dyson DC04 Motor Burn Out in Youtube.
