100-7552 Caterpillar Mechanical Diesel Injector Assembly; Compatible with 3304B/3306C engines; Dedicated injector for 12G/12H motor graders, 160H bulldozers, and construction machinery generator sets

Specifications:
OE Part Number 100-7552, Caterpillar vintage pencil-style mechanical fuel injector, standard mounting dimensions, allows for damage-free replacement of original equipment on-site, individually rust-proof sealed packaging, fully compatible with the factory fuel system calibration parameters for the 3304B and 3306C.

Compatible Models:
Compatible with Caterpillar 3304B and 3306C diesel engines; compatible equipment includes: 12G and 12H motor graders, 160H wheeled bulldozers, mining loaders, SR4 series diesel generator sets, stationary industrial power units, and marine diesel power equipment.

Materials and Manufacturing:
The valve body is machined from high-quality materials. The needle valve assembly undergoes high-precision hydraulic matching and lapping. The internal sealing O-rings are resistant to diesel corrosion and withstand high temperatures and pressures. They are designed to withstand harsh operating conditions such as construction site dust, heavy loads and vibrations, and alternating high and low temperatures, minimizing the risk of seizing or leakage.

Repair and Replacement:
Replace aged or damaged original injectors to resolve common issues such as poor fuel atomization, difficult cold starts, idle vibration, high fuel consumption, black exhaust smoke, and reduced power. These are standard replacement parts for construction machinery repair shops and mining maintenance facilities, and installation requires no modifications to the fuel system.

Stringent Quality Control:
All finished products undergo comprehensive bench testing for injection pressure, atomization quality, and sealing performance, with data benchmarked against original manufacturer specifications. Both brand-new and high-quality remanufactured parts are available, supporting both individual purchases and bulk stocking by repair shops.

Warranty: 6 months
