This engine oil filter is a genuine Claas component designed for the engine lubrication system of selected Claas combine harvesters. It removes particulate contaminants from the engine oil, ensuring that only clean oil circulates through the bearings, journals, and other internal engine components. A clogged filter restricts oil flow, which can lead to increased engine wear and reduced lubrication efficiency. The filter is constructed to match the original housing's seal groove and thread specification, ensuring a proper seal and correct bypass-valve operation. When replacing, lubricate the new gasket with clean oil and tighten the filter by hand until the gasket contacts the mounting surface, then give an additional three-quarter turn.
