Title: Rear axle clunk (S2R800) Post by: XJBaylor on May 24, 2008, 08:53:57 PM I just bought a 2006 S2R800, and noticed something odd. When I roll the bike there is a clunking sound coming from the rear axle. It happens about every 1/8th of a rotation. It sounds almost rubbery, as if the sound is being heard through the tire. Has anyone experienced this? Any clue as to what causes it?

Download the pdf parts manual from Ducati and it will give you a good picture Title: Re: Rear axle clunk (S2R800) Post by: DarkStaR on May 25, 2008, 07:20:21 AM Sounds like a cush drive rubber is floating around inside the wheel hub. Download the pdf parts manual from Ducati and it will give you a good picture It's an S2R. Can't be a cush drive in the wheel. Usually when the cush backs out on a S*R, it hits the eccentric adjuster. Title: Re: Rear axle clunk (S2R800) Post by: ducpainter on May 26, 2008, 03:28:17 AM It's an S2R. Can't be a cush drive in the wheel. I looked at the pdf file...Usually when the cush backs out on a S*R, it hits the eccentric adjuster. you're right. Could it be just bad cush drive rubbers?

The OP would have to isolate where the sound is REALLY coming from, taking account that the sound may be resonating through other/multiple parts.

On the S*R's the cush drive is via elastomeric bushes in the sprocket, these have been known to shear, almost always when this happens the bush backs out and contacts the eccentric hub and grinds away the adjusting flange. |
