Volvo Penta Oil Pump with Housing 23805982 – Essential Engine Lubrication System Component

Description

The Oil Pump with Housing, part number 23805982, is a fundamental component of the lubrication system in various Volvo and Volvo Penta engines. This assembly is responsible for drawing lubricating oil from the oil pan and circulating it under pressure throughout the engine. This continuous flow of oil is critical for multiple functions: reducing friction between moving parts, dissipating heat generated by engine operation, cleaning internal components by carrying away contaminants, and providing a hydraulic medium for certain engine functions. The “with housing” designation indicates it typically comes as an integrated unit, often including essential seals and covers, making replacement more straightforward.

This oil pump is widely compatible with a range of Volvo Construction Equipment, including excavators like the Volvo EC350D and EC250D. It also fits numerous Volvo Penta marine and industrial diesel engines, such as the TAD734GE, TAD752GE, TAD753GE, TAD754GE, TAD761VE, TAD762VE, TAD763VE, TAD764VE, and TAD765VE. Its broad application underscores its role as a standard, critical part within these robust engine lines. Cross-references for this part number include 21486014, 21009246, 20906321, and 20859343, among others, from various manufacturers.

Typically constructed from durable, high-strength cast iron or aluminum alloys, the pump is engineered to withstand the continuous mechanical and thermal stresses of engine operation. Most commonly, it is a rotor pump type, known for its efficiency and reliability in moving viscous fluids like engine oil. Key internal components include precisely machined rotors or gears that create the pumping action, ensuring consistent oil delivery. The design also often incorporates features for a shaft seal to prevent leaks. The approximate weight of this oil pump assembly is around 3.7 to 4 kg, reflecting its sturdy construction.

A malfunctioning oil pump is one of the most severe issues an engine can face, leading to insufficient lubrication, increased friction, overheating, and ultimately, catastrophic engine failure. Symptoms of a failing oil pump often include low oil pressure warnings, unusual engine noises (e.g., ticking or knocking from lack of lubrication), or engine overheating. Replacing a worn or damaged oil pump with a genuine or high-quality aftermarket unit like the 23805982 is paramount for protecting your valuable engine, ensuring its longevity, and maintaining optimal performance and reliability in demanding applications.
