In the realm of medium-to-heavy commercial vehicles, construction machinery, and large buses, Cummins ISL series engines have long served as the core power source for numerous critical pieces of equipment, renowned for their exceptional reliability, robust power, and outstanding fuel efficiency. However, despite their outstanding quality, prolonged high-load operation inevitably leads to performance degradation. While purchasing new engines could resolve this issue, the high cost often discourages many users. Traditional overhauls, meanwhile, frequently fail to restore the original stability and efficiency. Deeply understanding this market pain point, Keluo Construction Machinery leverages years of industry expertise and specialized technology to introduce the Rebuild Engine ISL service. This solution helps customers restart efficient and reliable power at a cost significantly lower than new engines.
The Cummins ISL engine warrants professional reconditioning due to its robust technical foundation. Featuring a fully electronically controlled design with displacements ranging from 8.9 to 9.5 liters, the ISL series offers a more compact structure and lighter weight compared to engines of equivalent displacement. Yet it delivers powerful performance and low-end torque rivaling larger displacement models across a broad power range of 290 to 385 horsepower. Equipped with an advanced high-pressure common rail fuel system and intelligent electronic control modules, it achieves precise fuel injection and complete combustion, ensuring outstanding fuel economy. It also works in synergy with the vehicle's transmission and braking systems to maintain optimal engine performance across varying operating conditions. These design elements strike an exceptional balance between power, economy, and reliability, establishing a robust technical foundation for restoring performance after reconditioning.
Keluo Construction Machinery's ISL engine refurbishment is far more than simple disassembly and repair—it is a systematic, standardized remanufacturing process. Every engine entering our facility undergoes complete disassembly and thorough cleaning. Professional technicians then conduct precise inspections and evaluations of all core components, including high-strength forged crankshafts, high-durability pistons, and specially treated cylinder liners. We strictly adhere to original manufacturer specifications. Components reaching wear limits are replaced exclusively with genuine Cummins parts or equivalent high-quality alternatives. Repairable core components undergo specialized processes like boring and coating to restore their original dimensions and performance. During assembly, we implement manufacturing standards equivalent to those for new engines. Each remanufactured engine undergoes rigorous load and performance testing on dedicated test benches, ensuring that critical metrics—including power output, torque, fuel efficiency, and noise levels—are restored to near-factory-new excellence.
