Im replacing the clutch in my 830. The pilot shaft bearing was destroyed, but the shaft seems to be ok. The crankshaft has a "Plug" in the end of it. Its very loose and easily moves around, also, its recessed in the crank. I think it should be tight in the crank and even with the end of the crank, but Im not 100 percent sure of this. I think the hole in the end of the crank is worn causing this problem. From what I can tell, my options are: 1. throw the plug away and hope for the best? 2. have a new plug made to fit the worn hole in the the crank and somehow bond it to the crank. 3. replace the crank. Hopefully someone has a better idea than I do. Any suggestions? Your help would be greatly appreciated.
