Rebuild Engine QSK60 is the flagship model of Cummins' QSK series, featuring an ultra-large displacement. After professional refurbishment by Keluo according to original factory standards, it leverages its core advantage of a 60L displacement to serve as the powerhouse for extreme heavy-duty applications such as super-large mining machinery, giant generator sets, and ocean-going vessels. Leveraging over 20 years of industry expertise, Keluo has identified two high-frequency, non-repetitive common faults and simplified repair methods for this engine. This empowers customers to rapidly troubleshoot issues, minimize equipment downtime, and reduce operational costs.
The Rebuild Engine QSK60's most distinctive advantage lies in its ultimate power and load-bearing capacity, derived from its top-tier, ultra-large displacement. With a displacement of 60L, it features a V-type 16-cylinder turbocharged intercooled design, delivering power ranging from 1193 to 1864kW and peak torque exceeding 9000N·m. Its power reserve significantly surpasses other models in the series, enabling effortless handling of prolonged, uninterrupted operations in extreme heavy-duty applications. Its cylinder blocks and crankshafts are forged from high-strength wear-resistant alloys. Combined with Keluo's precision refurbishment process, core components undergo specialized reinforcement and restoration. This delivers outstanding impact and wear resistance, extending service life to over 85% of a new engine's lifespan. It adapts to all types of demanding and extreme operating conditions.
Long-lasting durability and low-consumption energy efficiency represent another major unique advantage of this machine. It features an optimized fuel supply and combustion system that delivers exceptional power output while effectively reducing fuel consumption—achieving over 8% greater energy savings compared to standard engines in its class. Additionally, its reinforced sealing design minimizes oil loss. Combined with the premium OEM seals and wear-resistant components replaced during Keluo's refurbishment, this further enhances long-term operational capability and reduces the frequency of subsequent maintenance.
Tailored for top-tier extreme heavy-duty operations, Keluo has identified two common faults and their repair methods for this machine. The first is air leakage in the intake system, often caused by aging intake manifold gaskets or loose pipe connections. Symptoms include reduced engine power and increased fuel consumption. Repair involves replacing the original intake manifold gasket, tightening pipe connections, and verifying no leaks before restoring normal operation.
The second is electrical control system failure, stemming from poor wiring connections or damaged sensors. This causes difficult engine starts and abnormal operation. Troubleshoot by tightening wiring connections and replacing faulty sensors. Restart the engine for testing to ensure the control system functions properly. The procedure is straightforward, allowing customers to perform basic repairs themselves.
