8N-7003 8N7003 Mechanical Diesel Injector Assembly Compatible with CAT 3304/3304B and 3306 Engines; Specialized injector for motor graders, loaders, mining dump trucks, and generator sets

Specifications:
OE Part Number 8N-7003, Caterpillar pencil-type mechanical fuel injector, standard mounting dimensions, can be directly installed in place of the original equipment, compatible with the factory-calibrated fuel systems of the 3304 and 3306 series engines.

Model Compatibility:
Compatible with Caterpillar 3304, 3304B, and 3306 diesel engines; applicable equipment includes 12G/14G motor graders, 950/966 series wheel loaders, D250 mining dump trucks, stationary diesel generator sets, and mining and construction equipment.

Materials and Manufacturing:
The valve body is machined from high-quality materials, and the needle valves are precision-ground and matched. They withstand high temperatures and pressures, resist corrosion from impurities in low-quality diesel fuel, and are designed for harsh on-site conditions characterized by high dust levels, prolonged heavy loads, and rough terrain.

Repair and Replacement:
Replace old injectors with poor atomization or internal wear to resolve issues such as difficult cold starts, idle vibration, black exhaust smoke, high fuel consumption, and insufficient power. A common replacement part for construction machinery maintenance.

Stringent Quality Control:
All products undergo bench testing for injection pressure, atomization performance, and sealing integrity, with parameters meeting original equipment manufacturer (OEM) standards. We support both individual purchases and bulk orders from repair shops.

Warranty: 6 months
