Looking for a crankshaft for a MC 45.
Bob, I'm not sure about the Woodruff keyways, but everything else on the Mc30 and Mc40 cranks should be the same. Same ignition, same stroke. Ted
Should be the 58128 dual ball bearing crank.
Same crankshaft as a lot of the good saws used, I have a nice one from a 790 saw. Also have some with added counterweights for kart racing motors.
Tom, are any of those cranks for sale?
