ABSTRACT:
Lubricant is pumped into a lubrication system by an oil pump. Preferably the lubricant is drawn into the pump from an unagitated source. An eccentric pump rotor is received on the crankshaft and has a circumferentially extending recess. A radially extending drive pin is secured in the crankshaft and coacts with the ends of the recess to position the rotor in accordance with the direction of rotation of the shaft.
