294000-1240 1460A057 Common Rail Pump for Mitsubishi L200 Triton 4D56 Diesel Injection Pump 2940001240 Pump Assy

This heavy-duty diesel engine high-pressure common rail fuel pump (OE: 294000-1240) is a high-performance fuel pumping and control unit specifically designed for commercial heavy-duty and harsh operating environments. This product is perfectly compatible with Isuzu 4HK1, 6HK1, and other electronically controlled high-pressure common rail diesel engines, and is widely used in Hitachi ZX200-3, ZX240-3, and ZX270-3 series hydraulic excavators, as well as mainstream medium and heavy-duty trucks and dump trucks such as the Isuzu ELF and Forward.

This high-pressure fuel pump is comprehensively optimized around the design concept of "constant pressure and precise control." Its camshaft and dual plunger assembly undergo ultra-precision surface hardening and ultra-low friction coating treatment, enabling it to maintain excellent wear resistance even when facing complex and varied fuel lubrication properties. After replacing this high-pressure fuel pump, the improvement in actual equipment operation is immediate. Operators or truck drivers can intuitively feel that the engine starts crisply and responsively, and the throttle response is completely seamless. Even when facing heavy-duty challenges such as heavy excavation, deep mountain climbing, or high-angle fully loaded inclines, the high-pressure oil pump, relying on its sensitive electronically controlled intake control valve (SCV valve), can instantly establish and maintain a strong and stable rail pressure for an extended period. This completely solves the problems of intermittent engine weakness, stalling, misfires, and unstable engine speed caused by pressure leakage in older components, significantly reducing fuel waste.

• Self-operated manufacturing plant, direct sourcing, eliminating the layers of markups from traditional distribution networks: Addressing the long-standing monopoly of multinational distributors on spare parts for major heavy-duty trucks and construction machinery, resulting in high retail prices and slow technical feedback, we adopt a direct sales model from our own factory. This one-stop cross-border direct sales eliminates all intermediary profits, directly reducing users' replacement parts expenses and saving you or your fleet significant operating and maintenance costs.
• Dedicated Warehousing with Large Stock to Completely Eliminate Downtime and Delays Caused by Spare Parts Shortages: Logistics trucks and construction excavators are high-value operational assets. If they become inoperable due to fuel system failure, it will result in significant daily downtime losses and project delay penalties. Therefore, we implement dynamic inventory management with high reserve limits for our best-selling models. With ample stock, orders are processed and shipped within 24-48 hours of confirmation, providing rapid turnaround to help your equipment quickly return to work.
• 100% Microsecond-Level Fully Simulated Digital Test Bench Rigorous Quality Inspection to Eliminate the Risk of Defective Products Leaving the Factory: Addressing the common problems of internal high-pressure leakage, plunger jamming, and electronic valve malfunction in inferior small-factory oil pumps, every one of our high-pressure oil pumps undergoes a high-precision fully automated testing bench before leaving the factory. Under simulated extreme high temperatures and heavy loads, the oil pump's pumping efficiency, return oil volume, and SCV control accuracy are calibrated at multiple points (100%) to ensure that every product delivered to you has a wear-resistant lifespan that exceeds expectations.

• Municipal infrastructure road network paving and continuous excavation of hard soil layers: In urban rail transit or high-rise foundation construction sites with stringent schedule requirements and needing 24/7 uninterrupted operation, the Hitachi ZX240-3 hydraulic excavator equipped with a 6HK1 engine is continuously gripping hard soil layers at full power. As the bucket frequently cuts into hard rock layers, hydraulic resistance instantly surges to the system's redline. The 294000-1240 high-pressure oil pump, with its excellent pressure recovery speed, continuously outputs high-pressure oil, ensuring smooth low-speed, high-torque output from the excavator, preventing any lag or stalling during complex operations.
• Cross-regional fully loaded logistics routes and continuous steep mountain road transport: Heavy-duty dump trucks or vans loaded with large tonnage, high-value goods are traveling on inter-provincial trunk lines and continuous mountain roads. Facing long journeys and high-intensity, heavy-load climbing conditions, the driver adjusts gears by pressing the accelerator. The high-pressure oil pump, with its excellent pressure stability and rapid response, ensures that every drop of diesel fuel is fully atomized and combusted in the cylinder, maintaining ample climbing power while significantly improving exhaust smoke and effectively reducing overall fuel consumption.

A: We promise that the oil pumps sold on our independent website are 100% brand new, high-quality replacement parts, absolutely not second-hand, recycled, or refurbished parts. Because we operate our own factory directly online, shipping goods directly from our workshop warehouse to end users worldwide, we eliminate the commissions and expenses of multiple layers of distributors and physical stores, allowing us to pass on the true factory price directly to you.

A: We are well aware of the significant downtime and losses caused by heavy machinery downtime. This model is part of our core best-selling series, and our modern warehouse maintains ample stock year-round. Normally, after you complete payment for your order on a business day, the goods will be checked, shipped, and dispatched within 24 to 48 hours. With international express delivery, delivery typically takes 5-9 business days.

A: Modern diesel common rail systems are extremely precise, with zero tolerance for even the smallest metal shavings or impurities. Therefore, before installing a new fuel pump, please ensure your technician thoroughly cleans the original vehicle's diesel tank, common rail, and all low-pressure and high-pressure fuel lines. A brand new, genuine diesel fuel filter must also be installed. Ensuring a clean fuel system is a prerequisite for maximizing the new pump's performance and ensuring its extended lifespan.

A: As long as the product has not been opened or tested, its appearance and accessories are intact, and it does not affect our resale, we offer a 90-day return and exchange guarantee. Furthermore, this brand new fuel pump enjoys an extended 12-month warranty. If any quality malfunctions occur that are not caused by human error or contamination by inferior diesel fuel, our after-sales customer service team will provide you with technical analysis or free replacement service immediately.
