Title: Clutch rubber?
Post by: Thomas on May 23, 2020, 05:44:38 PM
While waiting for my cush sprocket I realised a kind of soft material (rubber?) under my clutch which is visible only at two clutch sprocket positions. What is it? Is a repair needed?

PS: I also wonder how to dsmantle the clutch basket.

Thomas,
Sorry I have no idea what this rubber is about but your sprocket was mailed last week so hope it is ok

Hi all,

To get to the bottom of the rubber issue I have searched for information about it and asked other colleagues. Then I took the clutch apart. To present this here in a comprehensible way I have written a little text about it.

what is in those photos is just perished material  from the circular ones in the sprocket,  its not meant to be there.

You can see the rubber and the special shaped washer in the lower right of this picture.
