Mechanical Injector Assembly 104-3377 1043377 Compatible with CAT 3306/3306B engines, 12H motor graders, 966F loaders, D250E mining trucks, and diesel generator sets

Specifications:
OE Part No. 104-3377, Caterpillar pencil-type mechanical fuel injector, standard mounting dimensions, allows for non-destructive in-place replacement of original equipment, and matches the factory-calibrated parameters of the 3306 model fuel system.

Model Compatibility:
Compatible with Caterpillar 3306 and 3306B diesel engines; compatible equipment includes: 12H motor graders, 966F wheel loaders, D250E mining dump trucks, stationary industrial generator sets, and mining construction machinery.

Materials and Manufacturing:
The valve body is machined from high-quality materials, and the needle valves are precision-ground and matched for optimal performance. They withstand high temperatures and pressures, resist corrosion from low-quality diesel fuel, and are designed for harsh operating conditions such as high-dust environments and heavy-duty, bumpy terrain on construction sites.

Repair and Replacement:
Replaces old injectors with poor atomization or those worn and seized, resolving issues such as difficult cold starts, idle surging, black exhaust smoke, high fuel consumption, and power loss. A common spare part for construction machinery maintenance and repair.

Stringent Quality Control:
All products undergo on-machine testing for injection pressure, atomization performance, and sealing integrity, with performance matching OEM standards. We support both individual purchases and bulk orders from repair shops.

Warranty: 6 months
