Product Description

612601080396 Fuel Injection Pump Assembly is a core diesel fuel system component responsible for generating and delivering high-pressure fuel to engine injectors with accurate timing and stable flow control.

In heavy-duty diesel engines, worn pump plungers, internal pressure loss, or damaged control valves may lead to hard starting, unstable idle, black smoke, insufficient engine power, increased fuel consumption, and injector malfunction.

This fuel pump assembly is widely used in export fleet maintenance, engineering machinery repair, diesel engine overhaul, and heavy truck aftermarket service.

Product Overview

This high-pressure fuel injection pump assembly is commonly installed on WEICHAI WP10 and WP12 engine platforms used in SINOTRUK HOWO trucks, SHACMAN heavy-duty vehicles, engineering machinery, and commercial diesel power systems.

Common Field Failure Case

Case 1

Vehicle: HOWO A7 Tractor Truck
Mileage: 520,000 KM
Problem: Engine hard start and unstable idle
Root Cause: Internal plunger wear caused pressure loss
Solution: Replaced 612601080396 injection pump assembly
Loss / Benefit: Restored fuel pressure and reduced injector stress

Case 2

Vehicle: SHACMAN F3000
Mileage: 610,000 KM
Problem: Black smoke and power reduction under load
Root Cause: Fuel metering valve malfunction
Solution: Installed OE-standard fuel pump assembly
Loss / Benefit: Improved fuel combustion efficiency and reduced fuel consumption

Case 3

Vehicle: Engineering Machinery Loader
Mileage: 8,300 Working Hours
Problem: Engine shutdown during heavy operation
Root Cause: Incorrect replacement fuel pump calibration
Solution: Verified OEM number and pressure mapping before installation
Loss / Benefit: Avoided repeated field repair and reduced equipment downtime
