Looking for some direction or information. I was given a crankshaft that allegedly came from a maule. It is a 4 cyl crank that appears to be relatively light wieght as it has holed thru the crank pins and holes in the prop flange, but I cannot find any part numbers on it. I have looked closely at the flange and all over it the only numbers I have found are a cast in number near the center journal that reads. W-G 9152-a. I also found numbers scribed into the prop flange and on the rear of the crank that read s-64493-1. A rough measurment of the journals is 2.365 on the mains and 2.215 on the rods. I have tried contacting lycoming and had no luck. Any assistance would be appreciated.
