Caterpillar original Caterpillar 212-3462 Diesel Engine Common Rail Fuel Injector for C12 3176C E345B Excavator Parts  original new injector

The Caterpillar 212-3462 fuel injector is an OEM-grade electronic unit injector (EUI) designed for CAT C10, C11, C12, C13, 3176B and 3196 diesel engine platforms. Built to original Caterpillar specifications, this injector delivers precise fuel metering through high-pressure injection exceeding 20,000 psi, ensuring stable fuel delivery and consistent cylinder performance under heavy-duty operating conditions. Hardened steel internal components, OEM calibration, and precision fuel atomization work together to improve combustion efficiency, lower fuel consumption, and reduce exhaust emissions across excavators, wheel loaders, mining trucks, generator sets, marine auxiliary engines and other industrial equipment.

This injector is engineered for high durability, corrosion resistance, and high-temperature tolerance, making it suitable for construction machinery, mining operations, quarry equipment and emergency power systems. ECM-controlled timing and fuel quantity management ensures accurate injection events, while low leakage performance and extended service life help reduce overall maintenance costs. Common injector-related symptoms such as hard starting, black smoke, white smoke, rough idle, power loss, excessive fuel consumption, engine knocking and cylinder misfire can often be traced back to worn or failed injectors.

For optimal performance and longevity, operators should use OEM fuel filters, drain water separators regularly, maintain fuel cleanliness and monitor fuel pressure consistently. During installation, clean the injector bore thoroughly, replace all O-rings and seals, inspect the injector harness, verify ECM fault codes, and perform a fuel pressure test along with a cylinder cutout test. Authorized cross reference numbers include 10R-0967, 203-7685, 208-9160, 211-3025, 212-3460, 212-3463, 212-3465, 212-3468, 212-3469 and 194-5083. Final compatibility should be confirmed using the engine serial number (ESN) or Caterpillar SIS parts system.
