ABSTRACT:
Spherical joint connecting rod holder rings. The holder ring is formed in two halves which define a socket in which a spherical small end of the connecting rod is retained. The ring further includes a vertical wall which acts as an oil dam to retain oil in a piston cooling gallery. One or more drain holes are formed in the ring to drain oil from the cooling gallery back to the engine crankcase. Futhermore, one or more grooves are formed in the socket surface in order to channel oil into the socket for lubrication of the spherical small end.
