Slipper clutch stacking - and other woes
I have just stripped and re-stacked my slipper clutch and have some observations.
First though, a question -
In order to get the stack height correct, I have used a friction plate as the final outer plate. Is this a bad thing?
If you know, please advise me before I go and do some mischief to the clutch - or worse.
The clutch is a 12 tooth, ball and ramp, 6 spring unit, using Ducati standard plates. Not sue of the make, purchased from Casoli, about £400.
The reason I set about re-stacking the clutch was I became aware that the slipper mechanism seemed to have stopped working - rear wheel chatter into corners, and no kick through the clutch lever.
On stripping the clutch I found that the ball bearings from the slipper mechanism had left their correct locations, and there were signs that some or all of the bearings had wandered within the clutch drum, fortunately only doing cosmetic damage.
I am certain that the clutch was installed in accordance with the diagrams, with the possible exception of 1 too many clutch plates, giving a stack height 2mm too great.
I was also surprised to see how quickly the tangs on the clutch basket have started to show wear from the friction plates. The unit has covered less than 4,000 miles and it looks like I will have to address this soon.
Any comments or advice gratefully accepted - especially on the friction plate as outer plate question.
If Dave Warnick reads this - I may want to buy back that 48 tooth diaphragm clutch if you haven't grown too attached to it!!
