Ok so I had to replace my chain as it had a couple of stiff spots that could not be loosened and as I took off the back wheel and the sprocket off the wheel the spacers and bits fell everywhere. I put it back together but couldn't work out where this piece went. Even with the manual handy. I have included a pic of the piece which I broke putting back in. As well as the diagram in the haynes manual. the Washer/spacer is made from a type of rubber or neoprene. Can anyone tell me which number part it is on the diagram? I guess it's pretty important but can I ride to the dealer to get the part? I think it is part 14? Anyone?
