rebuilt the clutch on our newest "O".
The old shaft was WORN, right where the front bearing was. I made a new shaft out of 5/8" steel and used a connector like the one that goes onto the shaft that goes into the reduction housing. I just put the new on in front of the flex ring and drilled the new shaft for the pin. It is now MUCH quieter with the new bearing!
While I was there, i replaced the spring with a yellow one that I had laying around. It looks great now! Much nicer than that rusty/worn shaft that was on there.
