Perkins original Perkins 235-2888 Injector Assembly Nozzle for Caterpillar C-9 E336D E330D Diesel Engine Spare Part new injector original new injector

The Perkins C-9 diesel fuel injector is supplied under authorized reference CA2352888 / 702511AT, with CA10R7224, CA2360962, and CA20R1931 as matching authorized identifiers, alongside AP63944. It is designed for the Perkins C9 engine family and is commonly fitted to heavy-duty machines such as the 330C, E330C, 330CL, and 330CMH excavators, with additional coverage across construction, mining, generator set, marine, and industrial power applications. Final suitability must be verified against the engine serial number, original injector number, and machine arrangement number before purchase. Each unit is engineered for accurate fuel metering, stable spray atomization, responsive solenoid control, and long sealing life under demanding industrial duty cycles, and can be offered as new, remanufactured, rebuilt, exchange, or tested stock to match different market requirements.

This Perkins C-9 injector carries multiple cross references including 10R-7224, 10R7224, 236-0962, 2360962, 217-2570, 2172570, 188-8739, 1888739, 20R-1931, 20R1931, 254-4340, 2544340, 235-9649, 2359649, 172-5780, 1725780, 153-7923, 1537923, 212-3462, and 2123462, allowing direct interchange across many Perkins C9 engine arrangements used in Caterpillar and Perkins-built equipment. Buyers should compare the OE stamping on the old injector, the engine serial plate, and the machine arrangement number to confirm the correct cross reference is selected. Whether the engine uses a common rail or HEUI fuel system, the corresponding cross number must be matched, because some supplier listings describe the same engine platform differently depending on emissions level and region.

Correct fitment of this Perkins C9 injector supports restored engine power, smoother idle, improved throttle response, lower fuel consumption, and reduced exhaust emissions. Maintenance practices include scheduled fuel filter replacement, clean oil in HEUI-related systems, inspection of injector wiring and connectors, fuel leak checks, ECM fault code scanning, and professional bench testing of flow, leakage, solenoid response, and spray pattern when performance issues arise. When one injector fails due to age, contamination, or flow imbalance, replacing the complete set is recommended to rebalance cylinder performance and minimize repeat labor, making this cross-referenced Perkins C-9 injector a practical and reliable service solution for workshops, fleet operators, and heavy equipment rebuilders worldwide.
