Cush drive

[phil on a fazer]

Howdy
 
A while a go i had my rear wheel out and took off the sprocket carrier (i think that's what its called?) and had a look at the cush drive rubbers. When i turned the wheel horizontally (with the cush drive facing down) a set of the rubbers fell out, another set half fell out and the other 2? stayed put.
 
So shall i buy some new ones? if so can you buy them individually or do you have to buy the set? let me guess...they cost a fortune?
 
Or shall i pack them out with old inner tubes?If so whats the best way of doing it? was thinking of taking the rubbers out them gluing strips of inner tube to them. Or is it a case of leaving the rubbers in situ and ramming the strips in so there super tight?
 
Thanks

Unless there's obvious freeplay, leave 'em alone.  Some will be marginally tighter fit than others but it's not unusual for a couple to drop out when inverted.

oh O.K, i thought the rubbers were supposed to be a tight fit
