ABSTRACT:
Method and apparatus for counterbalancing an internal combustion engine while maintaining a lubricant flow path for supplying lubricant to a crankshaft connecting rod journal is disclosed wherein a generally cylindrical mass of crankshaft material is removed from a region of the crankshaft located coaxial with the connecting rod journal for engine balancing purposes with that removed mass including a portion of the lubricant passageway which supplies lubricant to the connecting rod journal. The region is then bridged by a tubular lubricant conduit to re-establish the lubricant path to the journal. Preferably the lubricant conduit is tubular and press fit into the existing passageway portions on opposite sides of the region with the lubricant passageway typically being a hole of uniform circular cross section extending oblique to the crankshaft axis of rotation and with the hole inside diameter substantially matching the outside diameter of the tube.
