original 235-2888 High Quality Injector 172-5780 188-8739 217-2570 236-0962 for C9 Diesel Engine Excavator Part original new injector

Engineered specifically for C7 and C9 diesel platforms, the 235-2888 HEUI fuel injector delivers precise metering and high-pressure atomization to support stable combustion across demanding duty cycles. Its calibrated nozzle geometry promotes a clean fuel spray pattern, reducing black smoke and incomplete-burn residue while improving throttle response under variable load. The injector is indexed under multiple reference formats including 235-2888, CA2352888, 10R-7224, 236-0962, 217-2570, and 188-8739, allowing seamless lookup across distributor catalogs, reman supply chains, and B2B procurement databases.

Fitment covers excavators such as the 330C, E330C, 330CL, and 330CMH, alongside loaders, mining trucks, power generation sets, and broader off-highway machinery running the C7 or C9 powerplant. The heavy-duty internal construction withstands vibration, thermal cycling, and continuous high-pressure operation typical of HEUI hydraulic-actuation circuits. Operators are advised to verify engine serial number, ECM calibration, and emission configuration prior to installation, as these factors may influence compatibility within the C7/C9 engine family.

Routine maintenance supports long service life: clean diesel fuel, regular fuel filter replacement, water-separator draining, and periodic ECM fault-code scanning with injector balance or cylinder cutout testing help detect early performance drift. Replacing injector sealing washers during service is recommended, and full-set replacement may be considered when severe imbalance is present. Common warning symptoms include hard starting, rough idle, power loss, elevated fuel consumption, excessive exhaust temperature, and visible external leakage, all of which can be evaluated through fuel pressure testing and bench testing procedures.
