slipper clutch - ball and ramp type 
  so ive got me a slipper clutch!!!!
 
 but i dont know much about it, long story really about how i came about it but needless to say, i dont know how to tell how worn / good it is, what should i look for ??
 
 i can see the plates are a bit worn, so il need new ones if its going to be worth fitting the thing on, jsut looking for some pointers as to how i can tell if its all in a serviceable condition.
 
 i can post some pics if its useful but what would we need to be looking at?
 
 thanks
