Caterpillar original  235-2888 Injector Nozzle for C-9 Engine E336d E330d Excavator Fuel Injector Assembly Replacement for OEM new injector original new injector

The Caterpillar CAT C-9 diesel fuel injector 235-2888 is engineered as a direct original replacement and remanufactured option for the CAT C9 engine family, supporting equipment such as the 330C, E330C, 330CL, and 330CMH excavators. Built to deliver accurate fuel metering, stable spray atomization, and responsive electronic control, this injector maintains consistent combustion performance under demanding industrial duty cycles. Its durable sealing design and precision-machined internal components ensure reliable operation across construction, mining, generator set, and marine power applications powered by the C9 platform.

This C9 injector is available in multiple supply formats, including new replacement, remanufactured, rebuilt, exchange, and tested configurations, allowing distributors and fleet operators to select the option that best fits their maintenance strategy. The 10R-7224 reman variant is widely recognized as a premium remanufactured diesel injector for Caterpillar C-9 applications, while authorized cross numbers such as 236-0962, 217-2570, 188-8739, 20R-1931, 254-4340, and AP63944 provide flexible interchange across compatible C9 system configurations. Because the C9 engine family includes both HEUI and common rail arrangements, confirming the injector configuration by engine serial number before installation is recommended.

For long service life, operators should use clean fuel, replace fuel filters on schedule, maintain proper oil condition in HEUI-related systems, and inspect injector wiring harnesses and connectors for damage or leakage. When a single injector fails due to age, contamination, or flow imbalance, replacing the complete set can restore cylinder balance, reduce repeat labor, and lower overall maintenance cost for Caterpillar C9-powered heavy equipment.
