My DC17 Animal is about five years old. It recently has developed the common problem of the rattling brushbar, which makes a tremendous racket when the brush bar is rotating. The noise occurs on carpet or hard floors but only when the brushbar is in use. My model of the DC17 has a clutch.
I have done some Googling on the problem and accomplished the following: made sure there were no loose parts, clogs or blockages (did not solve the problem), made sure all hair was removed from the brushbar (did not solve the problem), replaced the belt with another Dyson belt (did not solve the problem), replaced the brushroll (did not solve the problem), removed the end caps of the brushroll and sprayed them with Teflon lube (seemed to reduce but not solve the problem). By the process of elimination, it seems as if the final step is to replace the clutch.
What is the consensus of the experts here? And is the DC 04/07/14 clutch unit also fitted into the DC17?
Thanks for any help and suggestions.
