SERIES 50 OIL FILTER

Two full-flow type lubricating oil filters are used on the Series 50 engine. The oil filters are mounted in a downward position. The filters are the throw away, spin-on type. See Figure 24358 . ‪

Spin-on Oil Filters

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. ‪
