Oil prevents metal to metal contact between moving parts of the engine. The lubrication system pumps oil throughout the engine and to the oil filter to be filtered.


Oil pressure switch

Activates a warning lamp if the oil pressure is insufficient.

Oil pump

Takes oil collected in the oil pan and pumps it under pressure to each part of the engine.


Relief valve

Relieves excessive oil pressure.

Oil strainer

A metal screen installed at the oil inlet which removes large particles from the oil.


Oil filter

Engine oil gradually becomes contaminated. The oil filter removes undesired particles from the oil.
