original 0R-8338 Fuel Diesel Injector Pump for 3508 3512 3500A Engine Excavator Truck Diesel Engine Parts Auto Spares Accessories Wholesale original new injector

Engineered for demanding heavy-duty operations, the 0R-8338 diesel fuel injector is a precision-built component for the 3500 Series engine family, including the 3508, 3512, 3512A, 3512B, and 3516. Cross referenced with 111-3718, 1113718, CA0R8338, CA1113718, and AM-0R8338, this injector delivers OEM-standard fuel atomization and stable flow rates required for high-pressure direct injection systems.

Manufactured from high strength alloy with OEM-grade Viton sealing components, the injector offers superior resistance to thermal and mechanical stress. It is OEM calibrated and flow-tested to ensure a precise spray pattern, minimum leakage sealing, and reduced emissions. Benefits include improved combustion efficiency, increased power output, and extended service life. Designed as a direct replacement, it supports power generation gensets, marine propulsion, mining trucks, oil & gas fuel systems, and emergency backup generators, backed by a 12-24 month warranty.

Recommended maintenance includes flow testing every 1,000 hours, fuel filter replacement at 250 hours, leak testing at 500 hours, and calibration checks at 2,000 hours. Prior to installation, inspect the cylinder head injector bore, verify fuel rail pressure, replace sealing washers and O-rings, and clean fuel delivery lines. Lubricate O-rings with clean diesel, torque to specification, prime the system, and validate no fuel leaks under pressure for optimal reliability.
