Weichai WD618 Common Rail Fuel Pump Assembly (Injector Pump Assy)
◆ Product Overview
A high-performance Common Rail Fuel Pump Assembly specifically engineered for the Weichai WD618 series diesel engine equipped with an advanced common rail fuel system. This direct OEM replacement for part number 612601080799 is the core high-pressure generating unit, ensuring precise fuel delivery, optimal combustion, and restoration of factory-rated power, torque, fuel efficiency, and emission compliance for heavy-duty trucks, construction, and industrial power applications.
◆ OEM Part Number
✓ 612601080799
◆ Compatible Engine & System
✓ Weichai WD618 Diesel Engine
✓ Common Rail Fuel Injection System
◆ Product Specifications
✓ Condition: 100% New or Premium Remanufactured (As Specified)
✓ Type: High-Pressure Common Rail Fuel Pump Assembly
✓ Application: Heavy-Duty Common Rail Diesel Engine for Trucks & Industrial Machinery
✓ Function: Generates and regulates the ultra-high-pressure fuel supply (typically 1800+ bar) to the common rail for precise electronic injector operation.
◆ Key Features
✓ Complete Ready-to-Install Assembly: Integrates the high-pressure pumping elements, fuel metering valve, pressure regulator, and associated housings for a comprehensive solution.
✓ Ultra-High Pressure Capability: Engineered to meet the stringent pressure requirements of modern common rail systems for superior atomization and combustion efficiency.
✓ Direct OEM Integration: Designed for seamless compatibility with the WD618 engine's Electronic Control Unit (ECU) and fuel system architecture.
✓ Performance & Emission Restoration: Corrects critical issues such as insufficient power, hard starting, excessive smoke, and diagnostic trouble codes related to fuel rail pressure (e.g., low/high-pressure faults).
◆ Quality Assurance
✓ Rigorous Performance Testing: Each assembly undergoes bench testing to verify fuel delivery, pressure curves, and control valve response across the entire operational range.
✓ High-Pressure Leak & Integrity Testing: All seals, fittings, and internal components are validated to prevent failures under extreme pressure.
✓ Electronic Function Verification: Integrated solenoids and sensors are tested to ensure proper communication and control with the engine management system.
◆ Installation Applications
✓ Replacement of a failed or degraded common rail high-pressure pump on Weichai WD618 engines.
✓ Repair of complex fuel system faults leading to engine derate, poor performance, or inability to start.
✓ Major overhaul during engine rebuild or scheduled maintenance of high-mileage/high-hour equipment.
✓ Preventive maintenance to ensure reliability and avoid costly downtime in critical haulage or industrial operations.
◆ Service Advantages
✓ Ensures Peak Engine Performance: Vital for maintaining the designed horsepower, torque, and responsiveness of the WD618 engine.
✓ Protects the Entire Fuel System: A reliable pump prevents damaging pressure fluctuations that can harm injectors and the common rail.
✓ Maintains Emission Standards: Correct rail pressure is essential for effective exhaust aftertreatment (SCR/DPF) operation and compliance.
✓ Comprehensive Solution: Replacing the complete assembly addresses the root cause of pressure-related issues more effectively than partial repairs.
