Perkins original Perkins 0R-8338 replacement for OEM fuel injector  original new injector

The Perkins 0R-8338 fuel injector is a high-pressure direct injection component engineered for the Perkins 3500 Series engines, including 3508, 3512, 3512A, 3512B, and 3516 models. Manufactured with high-strength alloy construction and OEM-grade Viton sealing components, this injector is calibrated and tested to original factory standards to ensure consistent spray pattern, precise atomization, and stable flow rate across demanding operating conditions. It is designed to deliver reliable fuel delivery while reducing emissions and improving overall combustion efficiency.

This injector serves as both an OEM replacement and a remanufactured solution, cross-referenced with part numbers 111-3718, 1113718, CA0R8338, CA1113718, and AM-0R8338. Its high resistance to thermal and mechanical stress allows it to perform in heavy-duty applications such as power generation gensets, marine propulsion and auxiliary systems, mining trucks, construction machinery, oil and gas fuel systems, industrial power modules, and emergency backup generators. The OEM-calibrated design ensures minimum leakage and extended injector life under continuous load conditions.

To maintain peak performance, recommended maintenance includes flow testing every 1000 hours, fuel filter replacement at 250 hours, leak testing at 500 hours, and calibration checks at 2000 hours. The Perkins 0R-8338 / 111-3718 injector is a dependable choice for operators seeking OEM-standard performance, increased power output, and reduced downtime for industrial, marine, and power generation diesel engine applications.
