ABSTRACT:
A crankshaft and connecting rod assembly, and method of assembling same, including a crankshaft having a tapered end, a crankpin, and a one piece connecting rod having a large end that is slipped over the tapered end of the crankshaft and onto the crankpin. A radially protruding portion is formed on the crankpin such that a leading face of the bearing assembly of the large end abuts the protruding portion. Thereafter, a retaining pin is inserted into a radially extending hole in the crankshaft such that the retaining pin retains a second and opposite bearing surface of the large end of the connecting rod, thereby preventing the connecting rod from excessive axial movement along the crankpin. The retaining pin is preferably a spring-like roll pin that is resiliently and frictionally press fit into the hole.
