Cum-mins Mechanical PT Fuel Injector 4914325 for NT855 / N14 / Classic Mechanical Diesel Engine
Cum-mins 4914325 PT Fuel Injector for NT855 / NTA855 / NH855 14L Diesel Engines
This OEM-grade Cum-mins PT fuel injector 4914325 is designed for selected non-certified 14-liter NT/NH-series mechanical diesel engines, including compatible NT855, NTA855 and NH855 applications widely used in generator sets, construction and mining machinery, marine equipment and industrial power units. Precision-machined alloy components provide accurate fuel metering and consistent fuel atomization during continuous full-load operation.
When correctly matched and calibrated, the injector helps improve problems associated with worn or faulty injectors, including insufficient power, black smoke, difficult cold starting, unstable idle, excessive fuel consumption and fuel leakage. Heat-resistant sealing components help withstand prolonged high temperatures and mechanical vibration. Every injector is bench-tested for fuel delivery, spray pattern, sealing and leakage before shipment to support stable and reliable engine performance.
We stock multiple quality options for Cum-mins PT Fuel Injector 4914325, including brand-new genuine, premium aftermarket and fully remanufactured units. Every injector is professionally calibrated and bench-tested before shipment. Final injector adjustment should be completed during installation according to the applicable NT/NH-series engine service manual.
We provide a 12-month global warranty, neutral export carton packaging, flexible MOQ and tiered bulk-order discounts for marine service centers, generator maintenance companies, construction and mining machinery repair shops, and diesel spare parts wholesalers worldwide.
Our standardized independent calibration workshop is equipped with dedicated PT fuel injector test benches. Every 4914325 injector undergoes 100% performance inspection, including injection quantity, spray pattern, sealing performance and fuel leakage testing, to maintain consistent and reliable quality.
