Abstract
A connecting rod including a generally vertical oriented rod section having a piston end and a connecting end. A non-through bore formed in the connecting end receives a pin mounted eccentrically on a shaft, such that rotation of the shaft causes the rod section to reciprocate. An axial groove formed in the bore allows air in the bore to escape during assembly. When a lubricant is disposed in the bore, the groove also provides lubrication over the entire length of the pin.
