Rear sprocket flange carrier worn?

[Yodasoldier]

Hi folks,
Been loving getting out in the sun on my CB550 
Noticed the rear sprocket was making a clunking sound occasionally and it looked as though there was a problem with the carrier. Close inspection (after dismantling) has shown that the sprocket carrier (flange) or where it fits onto the other part of the hub is worn as a previous owner has added a thin steel collar or sleeve which has broken up and is causing the clunking problem due to it being able to move slightly.
Would anyone know if wear on these parts this is a common problem ?
Is there a fix  or should i be looking for a new hub?
Any help would be appreciated.

if its a replacement i need ....anybody got one or can point me in the right direction?
oh and one more thing...

Ok quick update...
packed the cush rubbers with some cut to shape innner tube rubber, greased parts that needed greasing and reassembled....all seems good

are the cush rubbers available from anywhere? a search says no...

Cheers Odd job!
That's great will see if they post to UK 

one more part if anyone can help with, the back wheel has a D ring I think it's a flat sided oring. this appears to be very worn and could do with replacing . it is also an unavailable part from Honda.
cheers

I think it is an "O" ring just worn flat, do you have the part number as somewhere I have some old stock of some that may fit

[Yodasoldier]

Cheers Bryanj Part number is 91261323000 it is listed as a D ring 79x2.6

[Bryanj]

Thats a standard 500 four part and its not a D ring its an O ring 79mm ID by 2.6mm Xsect. I know i have some but can't get to my lockup till next week

[Bryanj]

Thanks Bryan, have sent email and thanks to Oddjob, Cush rubbers ordered and on their way cheers to everyone else for the help.

Anybody taking part in this this year it's a great cause and and there should be a ride near to everyone  up and down the country. Great excuse to get the bike out. A think I'll stick  a post on the forum.

Can't do Sunday as I work on Sunday night but wish i could

[Bryanj]

I owe you an appology, I just opened the bag of those "O" ring and they are in fact a D section  not a round section, but still the correct part for what you want.
