Work on the poor little direct coupled 2hp P-L continues and I could use some suggestions (medically possible and legal preferred :-). The oiling ring drivers were fitted loose and have spun for many a long year. Both have worn grooves in the crankshaft and the worst is about 0.040" deep and about the same width. I cannot turn it down to flywheel bore diameter as that would loose the step that locates the inner edge of the flywheel boss. In the worst case (flywheel side) the oiling ring has also made a groove in the crankshaft and lubrication became so marginal that the main bearing now spins in its housing. I don't think these little chaps were happy at
1000rpm!Any ideas for getting the oiling ring drivers to fit?
