Product Introduction

• Structure: A precision-engineered pump with a cast-aluminum housing, integrated high-pressure plungers, an electronic control unit (ECU), and solenoid valves for pressure regulation. It features multiple fuel outlets for direct connection to injectors, and a drive shaft for power transmission from the engine.

• Performance: Delivers precise, consistent fuel pressure (up to 1600 bar) to the common rail, ensuring optimal injector operation and combustion efficiency. The electronic control system adjusts pressure dynamically based on engine load and speed, improving fuel economy and reducing emissions.

Core Function

1. High-Pressure Generation: Converts low-pressure fuel from the transfer pump into high-pressure fuel for the common rail system, enabling precise injector atomization.

2. Dynamic Pressure Regulation: The electronic control unit adjusts fuel pressure in real time to match engine operating conditions, optimizing power delivery and fuel efficiency.

3. System Protection: Integrated pressure relief and safety valves prevent over-pressurization, protecting the pump, rail, and injectors from damage.

Fuel Injection Pump 612640080039 WEICHAI – OEM-Quality Replacement for Peak Engine Performance

When your fleet depends on uninterrupted power delivery, the Fuel Injection Pump 612640080039 WEICHAI stands as the heartbeat of your diesel engine’s fuel system. Engineered to match original factory specifications, this high-pressure fuel injection pump delivers precise fuel metering, optimal atomization, and consistent combustion efficiency across thousands of operating hours. METTLEAD Truck Parts brings this critical component directly from quality-certified production lines in China to your warehouse — at factory-direct pricing that protects your procurement budget without compromising reliability.

Why This Fuel Injection Pump 612640080039 WEICHAI Outperforms Alternatives

The fuel injection pump is not just another replaceable part — it governs fuel pressure, injection timing, and delivery volume for every cylinder in your WEICHAI engine. A substandard pump leads to power loss, excessive emissions, elevated fuel consumption, and premature engine wear. Here is what sets the 612640080039 Fuel Injection Pump apart:

• OEM-Grade Precision: Manufactured to match WEICHAI original tolerances (±0.002mm plunger fit), ensuring seamless integration without recalibration.
• Durable Internal Components: Hardened alloy steel plungers and barrels resist cavitation erosion and fuel-borne abrasives for extended service life.
• Stable Fuel Delivery: Maintains uniform injection pressure (up to 1,800 bar) across all engine speeds — from idle to full load.
• Emission Compliance: Supports China National IV/V emission standards by delivering accurately timed fuel pulses that minimize particulate and NOx output.
• Reduced Downtime: Drop-in replacement design means your technicians install it faster, getting trucks back on the road within hours, not days.
• Cost Efficiency: Factory-direct sourcing from METTLEAD eliminates middleman markups — procurement managers typically save 20–35% versus local aftermarket distributors.

Application Scenarios – Where This Fuel Injection Pump Works Hardest

The Fuel Injection Pump 612640080039 WEICHAI is purpose-built for heavy-duty commercial vehicles and industrial machinery powered by WEICHAI WP10 and WP12 diesel engines. In the real world, this pump earns its keep in the following environments:

• Long-Haul Logistics Trucks: SINOTRUK HOWO A7, HOWO T7H, and SITRAK C7H tractor units covering intercity freight corridors demand fuel pumps that sustain steady rail pressure over 12+ hour daily operating cycles.
• Construction & Mining Dump Trucks: SHACMAN F3000 and SINOTRUK HOWO mining tippers operating in high-altitude, dusty, and high-temperature conditions rely on this pump’s corrosion-resistant internals to avoid fuel starvation.
• Municipal & Port Vehicles: Concrete mixers, port terminal tractors, and refuse collection trucks equipped with WEICHAI engines benefit from the pump’s consistent low-speed torque delivery.
• Power Generation Sets: Stationary WEICHAI gensets in factories and data centers use this injection pump to maintain stable frequency output under variable electrical loads.

Wherever a WEICHAI WP10 or WP12 engine operates, this fuel injection pump is a mission-critical component that directly determines fuel economy, power output, and emission compliance.

Customer Case Study – Fuel Injection Pump 612640080039 WEICHAI in Action

A fleet maintenance company based in West Africa managed 45 SINOTRUK HOWO A7 tractor units operating across cross-border freight routes. Their procurement manager reported recurring fuel pump failures sourced from local aftermarket suppliers — pumps that lasted barely 40,000 km before exhibiting pressure drop and uneven cylinder fueling.

After switching to the Fuel Injection Pump 612640080039 WEICHAI sourced through METTLEAD Truck Parts, the results spoke clearly:

• Service life extended to 95,000+ km before scheduled preventive replacement — more than double the previous supplier’s lifespan.
• Fuel consumption dropped by approximately 4.2% across the fleet, measured over a 3-month monitoring period.
• Zero mid-route breakdowns attributed to fuel system pump failure during the first 6 months of deployment.
• Procurement cost reduced by 28% compared to their previous sourcing channel, even including international freight.

The client now orders WEICHAI fuel injection pumps, injectors, and fuel filters in quarterly consolidated shipments — leveraging METTLEAD’s full WEICHAI engine parts inventory to simplify vendor management.

Frequently Asked Questions – Fuel Injection Pump 612640080039 WEICHAI

What engines does the Fuel Injection Pump 612640080039 fit?

This pump is designed for WEICHAI WP10 and WP12 series diesel engines. These engines are widely installed in SINOTRUK HOWO, SITRAK, SHACMAN, and select FAW heavy trucks, as well as WEICHAI-powered industrial gensets.

Is this Fuel Injection Pump 612640080039 an original or aftermarket part?

It is manufactured to OEM specifications using identical materials, tolerances, and testing protocols as the factory-original part. It functions as a direct drop-in replacement with no modification required.

How do I verify that 612640080039 is the correct part number for my vehicle?

Check your engine nameplate for the WEICHAI engine model (WP10 or WP12) and cross-reference with the original fuel pump part number stamped on the existing unit. Our technical team can also verify compatibility if you provide your engine serial number.

What causes a Fuel Injection Pump to fail prematurely?

The most common causes include contaminated fuel (water or particulates bypassing the fuel filter), improper installation torque, running the engine with air in the fuel system, and using non-standard fuel filter elements that allow abrasives into the pump chamber.

Does this pump require calibration after installation?

For common rail systems, the ECU manages injection timing electronically. After physical installation, a diagnostic scan tool should be used to reset fuel system adaptation values. No mechanical timing adjustment is needed.

What warranty does METTLEAD offer on the Fuel Injection Pump 612640080039?

We provide a 12-month or 100,000 km warranty (whichever occurs first) covering manufacturing defects. Claims are processed with photographic evidence and a brief failure description — no complicated paperwork.

Can I order a sample before committing to bulk quantity?

Yes. We encourage sample orders so you can inspect quality, test fitment, and benchmark performance before scaling up your procurement volume.
