From memory of a previous post, which I can't find, there's two different types. They both work on the principle of ramps in the clutch drum forcing the pressure plate to ride up under back-torque. One type has bearings separating the ramps, the other type doesn't. I'd assume the bearings would make for a smoother and more consistent action, where the ramps w/o bearings would act different under varying temperatures. Simple physics. Can someone correct me, or expand on that one please?? |
