He y'all, Preformed a tune up. New plug, static timing, valve adjustment and points cleaned up. Then I noticed a rattle in the lower part of the case? Also noticed the clutch was slipping a bit. Tried adjusting the clutch with not much improvement. So I pulled the right lower side of the case. Then cleaned the oil screen which was 80% blocked. Not actually knowing where the oil slinger was located even after somewhat extensive on line research. So I pulled the two screw plate off of the clutch body. Was very suprised to see the nut in the center of the clutch was turning with the screw driver I was using to clean it out with. (Tried uploading a picture but I see that's not happening.) I would think that the washer behind it with the tabs should have the ears bent into the nut? Dose anyone know the torque that it applied to that nut? With all the crap I am cleaning out of the slinger and the screen I am wounding if I should pull the oil pump cover and check its condition? Dose anyone know of a way I can check the condition of the clutch plates without taking the clutch apart and dose anyone make a Heavy Duty set replacement clutch plates? I only want to do this once. Well I hope that tightening the nut will stop the rattle. I will try to upload pictures later after 3 attempts I am done trying for the night. Grrr. I will most likely be making a socket for that nut on the main shaft if I can't find one for a decent price. Will post updates on tool making for the main nut if anyone is interested. Thanks for your time and remember the great culling will continue until no one is left.
