Abstract
A crankshaft assembly including a pair of crankshafts and an intermediate crank arm, wherein a through opening is formed in a crank web of each of the crankshafts to extend axially of the respective crankshaft. In assembling the part, one crankpin of the intermediate crank arm is force fitted in an opening formed in a crank arm of the one crankshaft and a jig having a columnar portion is inserted in the through opening formed in the one crankshaft to support the one crankpin, thereby providing a crankshaft sub-assembly. When another crankpin of the intermediate crank arm is force fitted in an opening formed in a crank arm of the other crankshaft, the pressure applied to the crankpin is borne by the jig, so that the other crankshaft can be accurately secured to the intermediate crank arm.
