found this rubber piece on the floor. not sure, but i'm thinking it goes in the trailing arm bracket - correct? what's it for? i'm thinking it has something to do with the chain guard and/or mounting or maybe the chain oiler hardware. drawing a blank - ???



any help?

Is it solid or hollow as the the chainguard retaining bolt would normally go through that bracket?

One possibility is that it was a spacer substituted for the chain oiler tube which would normally have fitted where the two holes are in the chainguard ahead of the shock mount.

thanks for the reply -- it's solid. when I got the bike, the chain oiler was DOA and in pieces in the parts box. there wasn't a bolt for the chain oiler's location in the chain guard.

it appears the forward hole in the chain guard is what mates to that trailing arm bracket. I went into the garage and reassembled the chain guard. the rubber piece appears to be a spacer for the forward chain guard mount/bolt. the bolt is on the upper radius part of the bracket and the rubber block below the bolt. i'm second guessing here, but it looks like it goes together something like this -



the spacer keeps the back edge of the chain guard from resting on the trailing arm itself. again, second guessing....

Could perhaps be original but there's only the 1/4" bolt according to the diagrams and parts books.

so, i'm taking it that it should be there. wonder why it's not called out in the parts book? I guess we can say, puzzle solved. LAB - thanks for the help.


from the link...

Good find. I ha 've nt mounted my chainguard on the 850 but hope to someday. Will cobble something like this together from a bit of tubing.
Question: has anyone fashioned some sort of chain rub pad to fit over the swingarm chainguard bolt bracket? Seems odd the chain can just eat away at the bracket.

Yes ,that rubber part was originally fitted ,was/is on my 850 MkIIa .It stops the chain guard vibrating and holds up the bolt so chainguard does not lower and rub on top of chain .Not sure that it was itemised in the supplement parts book .
