Oil Filters. e. (1) Purpose. The oil filter removes most of the impurities that have been picked up by the oil as it is circulated through the engine. The filter is mounted outside of the engine and is designed to be replaceable readily. (ON SLIDE #194) (2) Filter Configurations. There are two basic filter element configurations: the cartridge type and the sealed canister type. (a) The cartridge-type filter element fits into a permanent metal container. Oil is pumped under pressure into the container, where it passes from the outside of the filter element to the center. From here the oil exits the container. The element is changed easily by removing the cover from the container when this type of filter is used. (b) The sealed canister-type filter element is completely self-contained, consisting of an integral metal container and filter element. Oil is pumped into the container on the outside of the filter element. The oil then passes through the filter medium to the center of the element, where it exits the container. This type of filter is screwed onto its base and is removed by spinning it off. (3) Filter Medium Materials. (a) Cotton waste or resin-treated paper are the two most popular filter mediums. They are held in place by sandwiching them between two perforated metal sheets. (b) Some heavy-duty applications use layers of metal that are thinly spaced apart. Foreign matter is strained out as the oil passes between the metal layers. (ON SLIDE #195) (4) Filter System Configuration. The full-flow system is the most popular in current engine design. All oil in a full-flow
