Ok well then we should mention that since this thread was started, you can now buy a 30 element one way clutch. I call it that because it replaces the original roller clutch, but the new design has no actual rollers. They look like little dog bones. Now there will be posters that will say you don't need this, and I cannot tell you why some guys have no trouble with the stock design, and others tell me they cannot keep a stock one from failing. According to ati, the roller clutch is the biggest weakness in the 904 and the new dog one style can take much more torque.
