Yanmar 119000-32001 Oil Pump Assembly

The Yanmar 119000-32001 oil pump is a critical lubrication system component designed for Yanmar 4TN100 and 3TN100 series diesel engines. This gear-type oil pump maintains consistent oil pressure and flow rate across engine operating speeds, ensuring adequate lubrication of crankshaft bearings, connecting rods, and valve train components. Constructed from high-strength aluminum alloy housing with precision-machined steel gears, the pump features a flange-mounted design with integrated pressure relief valve. The pump is driven directly by the crankshaft gear, providing positive displacement oil delivery proportional to engine speed. Compatible with Yanmar industrial engines used in mini excavators, compact track loaders, and generator sets.
