Engineered for demanding heavy-duty duty cycles, the 20R-1259 high pressure common rail fuel injector delivers OEM-level performance for C9 and C9 ACERT 8.8L inline six-cylinder diesel engines. Manufactured from premium alloy steel with advanced surface treatment and CNC machining to micron-level tolerances, this injector supports accurate fuel metering, superior atomization efficiency, and enhanced combustion performance in mining, construction, marine, and power generation environments.
The unit serves as a direct replacement referenced under cross numbers 237-3300, 236-3300, 10R-4761, 249-0712, and 328-2585, and is fully compatible with 330D, 336D, 950H, 966H, D6R, and D7R equipment, as well as commercial marine engines, tugboats, offshore support vessels, and industrial generator sets. High pressure resistance, corrosion resistant construction, and proven thermal stability maintain reliable output under sustained high engine temperatures. ACERT combustion control and optimized fuel delivery reduce emissions while lowering total fuel consumption across extended service intervals.
Installation requires cleaning the cylinder head bore, fitting new sealing washers, lubricating O-rings, torquing the hold-down clamp to service specification, programming the injector trim code, and bleeding the fuel system. Preventive maintenance—regular fuel filter replacement, clean diesel usage, pressure monitoring, and injector balance testing—maximizes service life and prevents hard starting, black or white smoke, engine knock, and elevated fuel consumption. Backed by a 12-month warranty for global aftermarket and OEM replacement markets.
