I think that cog is supposed to have three fins on it and yours has worn to a triangular shape. Look at the screenshot from the enlarged photo from your link.

I'll check for you tomorrow and post a better photo.
Hey, I never knew that soleplate was available on its own - I just looked them up and we can beat Currys on those.
That's useful, thanks for that!
Bit of a pain but I guess it's better than the motor going kaput.
What price do you guys do the soleplate for? The brushbar is also looking a bit knackered and I'm not sure if it's worth replacing the end cap while I'm at it. Can you also give me a price for all 3 if you stock them please?
I'm a bit concerned how much it's going to cost so I've also been looking on ebay for spares or repair heads, where the motors gone but the rest is usable as parts.
