Caterpillar original  C9 Diesel Fuel Injector 235-2888 for 324D 325D 329D E330D E336D Excavator Part, Replacement for OEM 10R-7224 236-0962 original new injector

Engineered for demanding off-highway duty cycles, the 235-2888 HEUI diesel fuel injector delivers precise metering and high-pressure atomization for C7 and C9 diesel engines. This heavy-duty unit is cross-referenced under CA2352888, 10R-7224, 107224, 236-0962, 217-2570, 188-8739, remanufactured code 235-2888-EX, and index number 4028, providing straightforward part-number lookup for global sourcing, fleet maintenance, and reman exchange programs.

Built to withstand continuous vibration, elevated heat, and cyclic combustion pressure, the injector uses a precision nozzle that breaks diesel fuel into fine particles for cleaner combustion, reduced black smoke, and improved throttle response. HEUI-type actuation enables electronically controlled fuel delivery for stable idle, lower emissions, and consistent power output under load. Robust internal construction supports long service intervals in industrial engines operating under sustained load, while multi-format part-number indexing simplifies aftermarket cataloguing and core-return workflows.

Public supplier listings verify fitment on excavator platforms such as 330C, E330C, 330CL, and 330CMH powered by C-7 and C-9 engines. Buyers should confirm engine serial number, machine model, old injector label, and ECM configuration before ordering. For maximum service life, use clean diesel fuel, replace fuel filters on schedule, maintain HEUI-grade engine oil, drain the water separator, and renew O-rings and seals at every service. Diagnose faults using ECM code scanning, injector balance tests, and cylinder cutout procedures.
