Abstract: The present invention provides and improved method of repairing a crankshaft body having a removable gear. The apparatus includes a crankshaft body having first and second end portions, one end portion carrying a raised annular rib that defines and enlarged diameter portion of the body, the body having a center of rotation during use. A ring gear is removably mounted at one of the end portions upon the annular rib. The ring gear is comprised of a pair of gear sections, each having a generally semicircular recess that is shaped to conform to the outer surface of the crankshaft body at the rib, a pair of opposed mating faces, and a generally semicircular outer toothed surface. A removable connection secures each gear section to the crankshaft body. The removable connection includes a plurality of openings in the crankshaft at the raised annular rib. The openings extend circumferentially about the crankshaft center of rotation.
