original 20R-5077 Excavator Fuel Injector 20R-5073 460-8213 456-3579 for Wheel Loader 966L 972M 366E C9.3 Common Fuel Line new injector original new injector

Engineered exclusively for the C9.3 engine platform, the 20R-5077 remanufactured fuel injector delivers OEM-level combustion precision across the full C9.3, C9.3 ACERT, and C9.3B configurations. Each unit is built to original factory calibration standards, restoring factory-rated injection pressure, spray atomization, and fuel delivery timing to keep heavy equipment engines operating within their original performance envelope.

The injector carries comprehensive cross-reference coverage with part numbers 460-8213, 456-3493, 367-4293, 363-0493, 364-8024, 171-9704, 196-1401, 173-9268, 456-3579, 198-7912, 456-3544, 456-3509, and 20R-5036, simplifying inventory management for distributors and fleet operators servicing mixed C9.3 fleets. It is validated for use in 330, 336, and 340 excavators, 950M, 962M, 966M, and 972M wheel loaders, C9.3 generator sets, industrial power units, mining trucks, and a wide range of auxiliary and marine diesel installations.

Every 20R-5077 is 100% performance tested on calibrated common-rail test benches, confirming flow rates, leakage thresholds, and response characteristics before shipment. The precision nozzle geometry and heavy-duty industrial construction support reduced exhaust emissions, improved fuel economy, and extended service life under continuous high-load operation. To maintain injector performance, operators should use OEM-quality diesel, replace fuel filters at scheduled intervals, and conduct injector balance testing during major service intervals.
