Oil Filter LF386 – 33014658Request Info
The oil filter helps remove contaminants from your machine’s engine’s oil that can accumulate over time as the oil keeps your engine clean.
The importance of clean motor oil
Clean motor oil is important because if the oil were left unfiltered for a too long, it can become saturated with tiny, hard particles that wear surfaces in your engine. This dirty oil can also wear down the oil pump’s machined components and damage the bearing surfaces in the engine.
How oil filters work
The outside of the filter is a metal can with a sealing gasket that allows it to be tightly held against the engine’s mating surface. The base plate of the can holds the gasket and is perforated with holes around the area just inside the gasket. A central hole is threaded to mate with the oil filter assembly on the engine block. Inside the can is the filter material, most frequently made from synthetic fiber. The engine’s oil pump moves the oil directly to the filter, where it enters from the holes in the perimeter of the base plate. The dirty oil is passed (pushed under pressure) through the filter media and back through the central hole, where it re-enters the engine.
Today’s oil filters differ in terms of appearances; however, their purpose remains the same.
