Two full-flow type lubricating oil filters are used on current Series 60 engines. The oil filters are mounted in a downward position. The filters are throw away, spin-on type. Prior to 1993 the Series 60 engines also had a bypass filter.
Oil supplied by the engine oil pump passes through the full-flow filters before reaching the various moving parts of the engine. The oil is forced by pump pressure through a passage in the filter adaptor and into the elements. Impurities are filtered out as the oil passes through the elements and out through another passage in the filter adaptor.
