A10E3-1009040A Oil Pan Is Suitable for Yuchai Engine Diesel Engine Parts Oil Pan

he A10E3-1009040A Oil Pan Assembly is an original equipment (OE) engine oil pan designed for Yuchai YC4A series 4-cylinder and certain YC6 series 6-cylinder diesel engines, including models such as the YC4A125-20 and YC4A140-30. As a critical part of the lubrication system, it serves to store engine oil, provide limited heat dissipation, and ensure consistent oil supply to the oil pump under various operating conditions—including steep inclines common in construction and off-road applications.

Constructed from high-strength cast iron (standard version), with some variants using aluminum alloy for weight reduction, this oil pan features a deep-sump design that increases oil capacity and improves oil stability during vehicle tilting—essential for machinery like loaders and excavators.

Equipped with a magnetic drain plug to capture ferrous wear particles, it plays a vital role in monitoring engine health and extending internal component life. It seals against the engine block via a dedicated gasket and must be installed with proper torque sequencing to prevent leaks.
