Perkins original Perkins 235-2888 Fuel Injector 10R-7224 387-9433 for Caterpillar C9 Excavator 324D 325D 329D E336D new injector original new injector

The Perkins 235-2888 HEUI diesel fuel injector is engineered as a direct replacement for Perkins C7 and C9 diesel engines, with verified application on the C9 platform commonly fitted in Caterpillar 330C, E330C, 330CL, and 330CMH excavators. Authorised OE reference 235-2888 and OE cross CA2352888 ensure engine-matched fitment, while replacement numbers 10R-7224, 107224, 236-0962, 217-2570, 188-8739, 235-2888-EX, and 4028 support database-friendly indexing across procurement, parts distribution, reman supply chains, and export trade channels.

Built for high-pressure atomization, the injector delivers precise fuel metering, stable combustion, and improved throttle response, reducing black smoke and incomplete combustion under heavy load. The heavy-duty body is designed to withstand vibration, heat, and continuous-duty operation in construction, mining, and power generation environments. Compatible with reman and exchange core-return programs, this injector integrates into B2B e-commerce and fleet maintenance workflows without ECM reprogramming in standard configurations, though fitment may depend on engine serial number, machine serial number, and emission configuration.

Maintenance requires clean diesel fuel, regular filter replacement, water-separator draining, and HEUI-suitable engine oil quality. Diagnostic steps include ECM fault-code scanning, fuel pressure testing, injector balance and cylinder cutout testing, visual leakage inspection, and injector seal replacement during service. Common failure symptoms such as hard starting, rough idle, power loss, excessive fuel consumption, and exhaust smoke can be addressed through systematic bench testing, with full-set replacement recommended when severe injector imbalance is detected.
