Caterpillar original Common Rail Diesel Fuel Injector 162-0212 for 3116 3126 3406B 320B 325B Excavator Truck Machinery Engine Parts 0R-4374 original new injector

The Caterpillar CAT 3116 3126 fuel injector 162-0212 1620212 is an industrial-grade Injector GP-Fuel assembly engineered for direct replacement on Caterpillar 3116 and 3126 six-cylinder diesel engines. Built around the OE reference 162-0212 / 1620212 and supported by cross numbers 0R-8463, 0R8463, 127-8230, 1278230, CA1620212, CA0R8463, and CA1278230, this injector is designed for heavy-duty diesel service markets that demand consistent flow output, stable atomization, and reliable cold-start response in demanding working environments.

The injector is widely used across marine propulsion, industrial generator sets, commercial truck powertrains, and construction machinery such as loaders and excavators. It is also installed on various off-highway heavy equipment powered by the 3116 and 3126 platforms. To protect engine balance, technicians typically recommend replacing the complete injector set when individual flow output or atomization characteristics begin to drift, preventing uneven cylinder contribution and supporting long-term engine reliability.

Before purchase, buyers are advised to confirm the engine model, engine serial number, original injector marking, fuel system type and arrangement, equipment model, and required quantity. Extended cross-reference numbers such as 7E-6193, 127-8216, 127-8228, 107-1231, 6I-3669, 0R-4368, and 0R-3762 should always be verified against the engine serial number, injector group, equipment model, and old injector marking to ensure correct fitment for the specific CAT 3116 or 3126 application.
