The 235-2888 is a Diesel Fuel Injector (specifically a HEUI type) used in Caterpillar (CAT) engines. It is a critical component of the fuel system that ensures precise fuel delivery for optimal combustion and engine efficiency.
Common Vehicle & Engine Fitment
This injector is primarily designed for the Caterpillar C9 engine series and is found in various heavy machinery:
. Excavators: 330C, E330C, 330D, 330DL, 336C, and 336D.
. Other Equipment: Used in CAT construction machinery, industrial equipment, and generator sets powered by the C9 engine.
Key Specifications
. Part Numbers: 235-2888, 2352888.
. Alternate/Reman Numbers: 10R-7224, 10R7224, 217-2570.
. Injector Type: HEUI (Hydraulic Electronic Unit Injector).
. Weight: Approximately 1.35 kg to 2.24 kg.
. Material: Heat-treated high-speed alloy steel with corrosion-resistant coating.
Installation & Maintenance Tips
. Trim Codes: Aftermarket or remanufactured injectors are often calibrated to OEM standard parameters. Experienced mechanics may need to calibrate them using previous trim codes.
. Electrical Safety: Wire and electrical parts are sensitive to short-circuiting. Ensure the battery is disconnected and connections are clean before installation to avoid damaging the ECU.
. Cleanliness: Contamination by fuel, oil, or other impurities is a leading cause of premature injector failure.
. Direct Replacement: These units are precision-engineered to match original factory fit and performance.
