Rebuild Engine QSK38 is the flagship model of Cummins' QSK series featuring an ultra-large displacement. After being rebuilt by Keluo to original factory standards, it leverages its 38L ultra-large displacement advantage to become the dedicated power solution for ultra-heavy-duty applications. Drawing on over 20 years of experience, Keluo has identified two high-frequency faults and simplified repair methods for this engine, helping customers quickly troubleshoot issues, reduce downtime, and lower operational costs.
The core unique advantage of the Rebuild Engine QSK38 lies in its robust power reserve and low-load operation characteristics, derived from its massive displacement. Featuring a 38L displacement, V-type 12-cylinder turbocharged intercooled design, power output ranging from 746-1197kW, and maximum torque of 5698N·m, it effortlessly handles continuous operation in diverse heavy-duty applications. Its low-load design minimizes component wear, and combined with Keluo's precision refurbishment process, it achieves over 85% of a new engine's lifespan.
Another key advantage lies in its low-maintenance, high-universality structural design. Components exhibit high interchangeability, with core wear parts compatible across the same series without customization. Modular construction allows complete removal of critical assemblies for streamlined servicing. Keluo's refurbishment process further optimizes maintainability by replacing original high-wear parts, reducing maintenance frequency.
Based on the characteristics of heavy-duty operations, Keluo has identified two common faults and their repair methods for this machine. The first is abnormal noise from the turbocharger accompanied by power loss, typically caused by impeller wear, loose bearings, or clogged intake pipes. During repair, replace the original turbocharger, clean the pipes, and test the power to restore performance. The second is excessive oil consumption, stemming from aged valve oil seals, worn piston rings, or pipe leaks. After diagnosis, replace OEM oil seals and piston rings, tighten pipe connections, and add compatible engine oil. Start the engine and observe no abnormal oil level—a straightforward procedure customers can perform themselves.
With over 20 years of industry expertise, Keluo delivers comprehensive support for this machine. Dedicated production lines undergo full-process inspection to ensure performance compliance. Leveraging a global dealer network and stocked inventory, we offer rapid delivery within 1-7 days alongside maintenance guidance and spare parts replenishment, helping customers reduce costs and boost efficiency.
