Still working on trying to diagnose lower right side crankcase noise '98 400f. It's for sure NOT the CB key. While I was putting the clutch back on the other day, I noticed something I thought was odd regarding the thrust washer between the inner and outer clutch baskets. I put on the outer basket, then slipped the thrust washer onto the splines and slid it toward the basket. The washer kept going toward the outer basket and dropped off the end of the splines where the shaft gets smaller in diameter. My logic would tell me that the washer should be resting on the splines and not behind them. But there it is, resting on the smaller diameter part of the shaft between the inner and outer baskets. It seems to me that it stays loose there and could rattle around??? Well what do you guys think????
