    Help 900 Clutch

    Hi Everyone,

    I need a spot of help, after running down to BIAMF and Stafford this weekend the gearshift on my 900 has got far more notchy and the clutch more grabby. I took the clutch cover off while down there and noted that the basket rim could be rocked about 3mm with the clutch engaged or not. Not to worry I thought it's probably one of those designs where the clutch basket does not form the innermost plain plate but rather floats behind the drum taking the drive from the plates alone. Turns out this is the case and the drum also contains the cush drive which explains some movement. On returning home I took the plates out and noticed one of the small springs labelled 1 in the drawing was broken and I can't work out how the other should be assembled. So I have two questions really:

    How should the little springs be assembled? Should they hold the innermost friction plate tang against the basket to prevent clutch chatter or should they push the plates out from behind in order to give smooth disengagement and prevent grabbing?

    and

    How slack should the clutch basket labeled 2 in the diagram be?

    Thanks

    Chris

    Sorry to lose you Vince and good luck with the sale! That picture is just the ticket. I can see the little spring at the top there mounted as an anti rattle doodah pressing the last friction plate against the basket. If it mounts this way then my clutch was assembled wrong. How much waggle does yours have in the basket?

    Thanks

    Chris

    There is about 2mm play when I hold the basket and try to rotate it clockwise and then anti-clockwise. When I remove plates, if I hold basket and pull it out and push it in, there is a similar 2mm play.
    I'm away this weekend so can't help futher till Monday. Hope this helps.
