Specifications:
OE Part Number 7W-7043, Replacement Part Number 0R3589. This is a Caterpillar 7000 series pencil-style injector with standard OEM dimensions that precisely matches the original vehicle mounting position. Each injector is individually packaged and can replace the original part without any modifications.

Compatible Models:
Specifically designed for Caterpillar 3406B and 3406C diesel engines; compatible with the full range of equipment powered by 3406B/C engines, including White GMC heavy-duty tractor trucks, Caterpillar genuine mining dump trucks, construction excavators, and generator sets.

Materials:
The valve body is made of high-quality steel; the needle valve is precision-ground; the internal high-pressure sealing pair undergoes wear-resistant heat treatment to withstand the engine’s high temperatures, high pressure, and frequent vibrations, ensuring corrosion resistance and preventing fuel leaks.

Repair and Replacement:
Replaces aged or damaged original injectors to resolve issues such as poor atomization, idle surging, difficult starting, black exhaust smoke, power loss, and high fuel consumption. Designed for direct in-place installation, these injectors are suitable for heavy-duty, high-frequency use in construction sites and mining operations.

Stringent Quality Control:
Every unit undergoes comprehensive bench testing for injection pressure, atomization, and sealing before leaving the factory. Parameters meet OEM factory standards, and each product is subject to random inspection and must pass before shipment. As a high-quality aftermarket replacement, it offers better value than OEM parts.

Warranty: 6 months
