I tried to measure the crank pully but it is on the engine. It is about 4
inches across. The pulley on the Judson is a little smaller. The Judson
crank pully is smaller than the regular crank pulley. I can't get an
accurate measurement with a tape measure and I don't have a calipers that
big.
Hope it helps,
