Ok, so when I took everything apart this is what I found, I take it my clutch is truly shot and this is not a bearing issue any longer? Do these plates just break apart over time? Part number searches are driving me nuts! It seems the Exmark part number is 631732 and the Warner part number is 5218-65. No one carriers the Warner part, it seems almost everyone is selling Stens part 255-552. Is Stens a good quality part? Any other suggestions? Here are some pics for your viewing pleasure. When you say seat it, what do you mean exactly? Proper torque?
