Caterpillar original 236-4086 Common Rail Fuel Injector for C11 C12 C13 Engine 140H 160H Motor Grader Excavator Truck Diesel Parts Replacement original new injector

Engineered as a direct OE-style replacement, the Caterpillar CAT C12 C10 3176 3196 Diesel Fuel Injector 236-4086 2364086 is designed to restore original combustion performance on demanding heavy equipment. Precision fuel metering is delivered through an optimized internal flow path and calibrated nozzle geometry, supporting stable combustion, reduced misfire, lower visible smoke, and improved fuel economy across variable load conditions commonly seen in excavators, on-highway trucks, stationary generator sets, and marine power packages.

Built for rugged operating environments, the injector features a heavy-duty body construction, hardened internal components, and high-quality seal materials to withstand high cylinder pressures and prolonged duty cycles in mining, construction, and industrial engine platforms. The optimized spray pattern promotes better atomization at the nozzle tip, helping the engine maintain efficient air-fuel mixing and consistent cylinder-to-cylinder output. Each unit is backed by tested-before-shipment quality control covering flow testing, leakage testing, spray pattern inspection, and electrical response verification to ensure reliable installation and service life.

Multiple cross-reference numbers are supported, including 10R-1268, 10R-1256, 223-5327, 10R-1003, 212-3460, 229-8842, 10R-0960, 317-5278, 20R-0055, 350-7555, and 20R-0056, simplifying procurement and inventory management for fleet operators and distributors. Remanufactured and replacement units are available to offer purchasing flexibility, and the export-ready packaging supports safe international shipment. Customers should always confirm compatibility by matching the engine serial number, arrangement number, and the originally removed injector number before purchase.
