Patent ID: 7703431

Claim:
An apparatus for an internal combustion engine with a crankshaft, a cylinder and a reciprocating piston located within the cylinder, comprising: a shank with two ends, a first pair of abutting surfaces, a first bearing support surface and a pair of laterally facing surfaces, each one of said laterally facing surfaces being substantially perpendicular from a different one of said first pair of abutting surfaces and being disposed at outermost sides of the shank, one end of said shank being attachable to the reciprocating piston and the other end of said shank being mountable to a crankpin of the crankshaft along said first bearing support surface; and a cap with a second pair of abutting surfaces, a second bearing support surface and a pair of projections, each one of said projections extending substantially normally from a different one of said second pair of abutting surfaces, said projections being adapted and configured to slidingly receive therebetween in an interference fit said laterally facing surfaces, said cap being mountable to the crankpin along said second bearing support surface with said abutting surfaces disposed on opposite sides of the crankpin; wherein said interference fit enabling said projections of said cap to compress said laterally facing surfaces of said shank from the outermost sides of the shank, when said cap and said shank are mounted to the crankpin and each one of said first abutting surfaces are in contact with a different one of said second abutting surfaces.
