As Cummins’ flagship large-displacement heavy-duty engine, the QSK38 delivers a peak power output of 3,200 horsepower and exceptional load-bearing capacity, making it the exclusive power source for core equipment such as large mining machinery, super-heavy-duty trucks, and large generator sets. Under prolonged, high-intensity operation, the QSK38 is prone to issues such as power degradation and rising maintenance costs. New engines are prohibitively expensive, and standard rebuilds often fail to match its flagship performance. Keluo’s Rebuild Engine QSK38, featuring OEM-grade standards and customized fitment, breathes new life into this flagship powerplant, delivering both long-term reliability and cost control.
As a 16-cylinder, high-displacement heavy-duty engine, the QSK38’s core strengths lie in its exceptional power and outstanding durability, making it widely used in demanding applications such as mining overburden removal and large-scale infrastructure projects. Such equipment often operates continuously for 24 hours a day under complex conditions involving high temperatures and dust. After prolonged operation, core components experience normal wear and tear, leading to unstable power output, increased fuel consumption, and more frequent maintenance—all of which impact operational efficiency. For enterprises, replacing the engine with a new one poses a significant financial burden. Standard refurbishment typically involves replacing only basic components, which fails to restore the engine’s flagship-level power and durability, making it difficult to meet demanding operational requirements.
Based on the specific characteristics of the QSK38, Keluo utilizes a dust-free workshop to completely disassemble and thoroughly clean the entire engine. Through professional non-destructive testing, we identify and address hidden wear and tear. We select Cummins-grade original core components, precisely match them to the 16-cylinder power structure, and calibrate the engine strictly according to original factory specifications to ensure that the remanufactured engine meets flagship standards in terms of power, durability, and fuel efficiency.
The core value of the QSK38 rebuild engine lies in its "long-term stability and cost control," which aligns with the operational needs of heavy-duty equipment. Compared to a brand-new QSK38, the procurement cost of a Keluo rebuilt engine is only 30%–45% of the new unit’s price, significantly reducing financial pressure. Additionally, it is ready for immediate installation, minimizing downtime and associated losses. At the same time, we enhance the wear resistance and impact resistance of core components while optimizing cooling and sealing structures, enabling the rebuilt engine to achieve a service life of over 80% that of a new unit and reducing maintenance frequency by 60%, thereby realizing “one rebuild, long-term benefits.”
Thanks to its proven engine rebuilding technology and comprehensive service system, Keluo has earned recognition from customers both domestically and internationally for its rebuilt QSK38 engines. We have a dedicated team of QSK38 overhaul engineers who can customize performance parameters for various applications, such as mining and port operations. Leveraging our global supply chain, we ensure rapid delivery and provide comprehensive support—including genuine spare parts, on-site installation guidance, and long-term maintenance consulting—to guarantee the smooth operation of your equipment.
