Oil Pump

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

The heart of the system is a positive displacement internal gear oil pump.

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

  1. The oil pump is mounted on the front face of the cylinder block.
  2. The inner rotor is piloted on the crankshaft post and is driven through flats on the crankshaft.
  3. System pressure is limited by an integral, internally-vented relief valve which directs the bypassed oil back to the inlet side of the oil pump.
  4. Oil pump displacement has been selected to provide adequate volume to make sure of correct oil pressure both at hot idle and maximum speed.
  5. The relief valve calibration protects the system from excessive pressure during high-viscosity conditions.
  6. The relief valve is designed to provide adequate connecting rod bearing lubrication under high-temperature and high-speed conditions.
