I would probably want to replace the whole clutch assembly. If I do it at all. I'm still not 100 percent convinced that's the problem because the brush roll seems to spin fine. That rattling sound I hear when I push the machine forward fast could be the baby wheels on the sole plate spinning. Thank goodness the carpet in my apartment is very low. Dysoninventsbig, thanks for the link to instructions on how to replace the bet. WHAT AN INVOLVED PROCESS... Someone should AT LEAST slap good ol James in the face for creating such a contraption.... and then lock in in a room with only a dirt devil and force him to vacuum with it for the rest of his life.
I hate that Dyson lies to its customers about having automatic height adjustment... when in reality it is non-existent height adjustment. Other manufacturers do that too, but they don't cost what the Dyson does. The soleplate pivots, but that does NOT change one bit the height of the brush roll.
Oh yeah, when I was naming my collection, I forgot a very special member. My Sanitaire SC887! I love the messy, but powerful thing.
