Caterpillar original Caterpillar 0R-8867 diesel fuel injector new injector original new injector

The Caterpillar 0R-8867 fuel injector is engineered as a direct OEM remanufactured replacement component for CAT 3114, CAT 3116, CAT 3116TA, CAT 3126, CAT 3126B, and CAT 3126E diesel engines. Manufactured to original factory specifications, this injector assembly delivers consistent fuel metering and stable injection pressure across demanding industrial operating cycles. The unit is fully interchangeable with cross reference numbers 140-8413, 4P-2995, and 0R-3190, providing a reliable solution for fleet maintenance, engine overhaul, and replacement part sourcing.

Constructed with high-precision machining and hardened internal components, the 0R-8867 ensures uniform fuel atomization and optimized spray pattern distribution, directly supporting improved combustion efficiency and reduced exhaust emissions. A specialized corrosion-resistant coating protects critical internal surfaces from fuel contamination and moisture exposure, while high-temperature resistant materials enable continuous heavy-duty operation in harsh environments. OEM dimensional accuracy guarantees a true drop-in fit without modification, simplifying installation and minimizing equipment downtime.

This injector is suitable for a wide range of heavy-duty applications, including construction machinery, mining equipment, industrial generator sets, marine engines, agricultural machinery, heavy transportation vehicles, and oil and gas field equipment. To maintain optimal injector performance and service life, operators should use clean diesel fuel, replace fuel filters at recommended intervals, avoid water contamination, inspect for injector leakage periodically, and monitor engine exhaust condition as part of routine preventive maintenance procedures.
