Product Introduction

The Lubricating Oil Pump, also known as the oil pump, is a vital component in a truck's engine. Its main function is to circulate oil throughout the engine to reduce friction and heat between moving parts. The 3966840 model is a specific part number used in certain types of trucks. It works by drawing in oil from the oil pan and forcing it through the engine's lubrication system under pressure. This ensures that all of the engine's components receive enough lubrication to run smoothly and efficiently. A faulty or worn-out oil pump can cause serious damage to an engine, so it's important to regularly check this component and replace it if necessary.
