Specifications:
OE Part No. 100-7559, Caterpillar pencil-style mechanical fuel injector, standard mounting bore and overall length, direct in-place installation without modification, compatible with the factory calibration of the 3306 engine fuel system.

Compatible Models:
Compatible with Caterpillar C9.3 diesel engines; compatible equipment includes Caterpillar E336GC and E345GC crawler excavators, medium-duty mining dump trucks, stationary industrial diesel generator sets, and mining and construction equipment.

Materials and Construction:
The housing is made of high-quality materials, with precision-ground and matched needle valves. The internal sealing components are designed to withstand high pressure, high temperatures, and corrosion from contaminated diesel fuel, making them suitable for dusty construction sites and long-term heavy-duty, rough-terrain operations.

Repair and Replacement:
Replaces original injectors that have aged, seized, or exhibit poor atomization, resolving common issues such as difficult cold starts, idling vibrations, black smoke emissions, excessive fuel consumption, and reduced power. A commonly used spare part for construction machinery maintenance.

Stringent Quality Control:
All finished products undergo bench testing for injection opening pressure, atomization performance, and seal leakage, with parameters matching OEM specifications. We support both individual orders and bulk purchases by repair shops.

Warranty: 6 months
