Engine Oil Pump Assembly 612630010256 for Weichai WP12 Series / SHACMAN F3000/X3000 Heavy Duty Trucks

• Pressurized Lubrication: Draws oil from the sump and pressurizes it through the main oil gallery to all bearing surfaces, creating a protective oil film to reduce metal-to-metal wear.

• Cooling & Cleaning: The continuous oil flow carries away friction-generated heat and flushes out abrasive debris, providing auxiliary cooling and cleansing functions.

• Durable Gear-Driven Design: Constructed with hardened steel gears to withstand high torque loads from heavy-duty diesel engines, offering proven reliability in harsh operating environments.

• Integrated Pressure Regulation: The built-in relief valve is critical for maintaining proper system oil pressure. Premature or delayed valve opening can lead to low oil pressure (causing bearing/seizure damage) or excessively high pressure (leading to seal leaks).

• Truck Brands: SHACMAN Delong F3000 / X3000 series; FOTON Auman series.

• Compatible Engines: Weichai WP12.375E40, WP12.430E50, WP12S400, and other WP12-series variants.

When installing or servicing this oil pump, the following associated components are typically involved:

• Timing Gear Housing: Provides the mounting base for the pump assembly.

• Crankshaft Gear: Supplies the driving force via the gear train.

• Oil Strainer (Pickup Tube): Mounted at the pump inlet to filter out large contaminants before they enter the pump cavity.
