0R3423 7W-7026 Mechanical Diesel Injector Compatible with Caterpillar 3406B/3406C/3412/3412C engines, D9R/D9GC bulldozers, and SR4 generator sets

Specifications:
OE Part Number 0R3423, 7W-7026, Caterpillar 7000 Series pencil-type mechanical fuel injector. Designed for direct, damage-free replacement of original equipment parts. Sealed, rust-proof, and individually packaged. Fully compatible with the factory calibration parameters of the 3406 Series engine fuel system.

Compatible Models:
Compatible with Caterpillar 3406B, 3406C, 3412, and 3412C diesel engines; compatible equipment includes: D9R and D9GC crawler bulldozers, SR4 diesel generator sets, heavy-duty mining dump trucks, oilfield construction machinery, and stationary industrial power units.

Materials and Craftsmanship:
The valve body is made of high-quality materials, with the needle valve precision-matched and honed hydraulically. Internal seals are designed to withstand high pressure, high temperatures, and corrosion from low-quality diesel fuel. They can endure long-term exposure to heavy-duty mining vibrations, extreme temperature fluctuations, and dusty, harsh operating conditions without seizing or leaking.

Repair and Replacement:
Replaces aged or damaged original injectors to resolve issues such as poor fuel atomization, difficult cold starts, idle vibration, lack of power, high fuel consumption, and black exhaust smoke. A standard replacement part for mining maintenance shops and construction machinery repair facilities, it can be installed without modifying the fuel lines.

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

Warranty: 6 months
