c-aterpillar Injector M11 Series (Part Number: 4903474) Product Details

The c-aterpillar 4903474 fuel injector is a high-precision, OEM-standard common rail injector specifically engineered for the c-aterpillar M11 series diesel engines, and it is fully compatible with Cummins engine models including M11, ISM11, and QSM11[8]. As a critical core component of the engine’s fuel injection system, it is widely applied to construction machinery, heavy-duty trucks, excavators, loaders, buses, and industrial power units equipped with these engines, serving as a reliable replacement part for maintenance and repair[8]. Its outstanding fuel atomization performance, stable delivery accuracy, and strict compliance with ISO 9001, TS 16949, CE, CCC, and RoHS certific-ation standards[8] are essential to ensuring efficient fuel combustion, stable engine power output, optimized fuel economy, and long-term operational durability of the M11 and compatible Cummins engines. Produced in certified manufacturing facilities with rich export experience, this injector strictly follows the design specific-ations and material requirements of the c-aterpillar M11 series, adopts high-quality alloy steel as the main material, and undergoes rigorous quality control throughout the entire production process—from raw material procurement to final assembly and functional testing, with 100% professional performance testing before delivery to ensure consistent and reliable performance. We implement a comprehensive quality control and validation system covering quality, packaging, delivery, and after-sales service to guarantee product stability and consistency. As a key matching part for M11, ISM11, and QSM11 fuel injection systems, it integrates advanced precision machining technologies, enabling it to withstand harsh working environments such as high temperature, high pressure, and long-term continuous operation. This scientific design not only effectively reduces fuel consumption and exhaust emissions but also enhances wear resistance and corrosion resistance, significantly extending the service life of both the injector and the engine. As a direct bolt-on OEM replacement part, it requires no installation modific-ations, is available with standard carton packaging or customized packaging upon request[8], and is backed by a 3-month limited warranty[8], along with efficient after-sales support and timely delivery, making it a cost-effective and reliable maintenance solution for c-aterpillar M11 engine users in construction, heavy-duty transportation, mining, and industrial sectors. It is widely recognized as a high-quality matching part for M11, ISM11, QSM11 engine fuel injection systems, compatible with various M11-based equipment, with a minimum order quantity of 1 piece[8] to meet the purchase needs of individual users, bulk buyers, and maintenance service providers.
