original 350-7555 Fuel Injector 212-3463 20R0056 10R1003 For C12 Excavator Parts Replacement for OEM new injector original new injector

Engineered exclusively for the C12 and C10 diesel engine platform, the 350-7555 fuel injector delivers precise fuel metering that matches the combustion requirements of these proven industrial power units. Each injector is built to fit directly into the C12 and C10 cylinder head, ensuring proper spray pattern, injection pressure, and timing calibration for stable operation across heavy-duty work cycles in excavators, loaders, mining trucks, and generator sets.

This injector assembly is calibrated to restore factory-level performance on -powered machines such as the 345B, 365B, 972G II, R1600G, and 725, as well as CPT372 and dedicated C10 and C12 engine units. The wear-resistant internal components and high-grade nozzle maintain consistent atomization, supporting smooth idle, balanced cylinder contribution, reduced exhaust smoke, and improved fuel economy even under continuous load.

Each unit is individually tested for flow rate, leakage, and spray pattern before shipment, and is supplied in sealed packaging to preserve cleanliness until installation. To maximize injector service life on C12 and C10 engines, operators should use clean diesel, replace fuel filters on schedule, drain the water separator regularly, and monitor for symptoms such as hard starting, rough idle, misfire, or elevated fuel consumption that may indicate injector service requirements.
