original 0R-3190 0R3190 Fuel Injection Nozzle Engine Injector Replacement for 7E-8729 7E8729 3114 3116 3126 E320L Excavator Accessories new original new injector

The 0R-3190 fuel injector is engineered as a direct replacement for the 3116 series diesel engine, delivering precise fuel metering and consistent atomization to support stable combustion across industrial duty cycles. Built with heavy-duty alloy steel and precision-machined internal components, the injector is designed to meet original specifications for flow rate, spray pattern, and sealing performance. Its application coverage extends to the 3114 engine family, making it a flexible solution for operators managing mixed heavy equipment fleets. Multiple authorized cross references including 0R-3190, 7E-8729, 0R-3002, 418-8820, CA0R3190, and CA7E8729 allow straightforward identification, simplified procurement, and reduced inventory complexity for distributors and service workshops.

Installation on E200B and EL200B excavators, IT12B, IT14B, and IT14F integrated tool carriers, as well as 910E and 910F wheel loaders, is supported by direct mechanical compatibility. The injector assembly is suitable for construction sites, mining operations, earthmoving projects, road building, agricultural machinery, material handling fleets, and general industrial engine applications. Each unit is supplied in sealed anti-rust packaging to preserve component integrity during storage and global shipment, ensuring ready-to-install condition upon delivery. Replacement flexibility allows service operations to service individual cylinders or replace the full set for better engine balance and long-term performance consistency.

To maintain reliable operation, clean diesel fuel should be used, fuel filters must be replaced at the recommended service interval, and the water separator should be drained regularly. Periodic inspection of injector return flow, leakage, and spray pattern is recommended, along with monitoring of exhaust smoke color, idle quality, and engine balance. When multiple units show wear, replacing the injectors as a matched set helps restore even cylinder performance.
