APPARATUS AND METHOD FOR REPLACING AN OIL PRESSURE REGULATING ASSEMBLY AND A HIGH PRESSURE RELIEF VALVE ASSEMBLY

摘要

A method of increasing oil pressure in a heavy duty truck engine lubricating system is provided. The lubricating system comprises an oil pressure regulating assembly (30) mounted in an oil filter base (14) and having a main spring (38) to regulate oil pressure, and a high pressure relief valve assembly (36) mounted in the oil filter base (14) and having a peak clipping spring (52) to relieve oil pressure when the pressure exceeds a specified limit. The method includes the steps of replacing the main spring (38) with a replacement main spring (38) having a higher spring constant and replacing the peak clipping spring (52) with a replacement peak clipping spring (52) having a higher spring constant. A replacement kit for increasing oil pressure is also provided.
