Oil Pump

The lubrication system is designed to provide optimum oil flow to critical components of the engine through its entire operating range.

Generically this design is known as a gerotor pump, which operates as follows:

• Oil pump displacement has been selected to provide adequate volume to make sure of correct oil pressure both at hot idle and maximum speed.
• The oil pump is mounted on the bottom side of the crankshaft.
• The oil pump is driven by a oil pump intermediate shaft.
• The relief valve calibration protects the system from excessive pressure during high viscosity conditions.
• The relief valve is designed to provide adequate connecting rod bearing lubrication under high-temperature and high-speed conditions.
