Caterpillar original 4P-2233 Excavator Fuel Injector Replacement for 3114 3116 3126 Diesel Engine Truck Sprayer Construction Machinery Parts original new injector

The Caterpillar CAT 3116 fuel injector 4P-2233 4P2233 is a heavy-duty mechanical injector assembly engineered for the CAT 3116 diesel fuel injection system. It is built to deliver consistent fuel atomization, accurate fuel metering and balanced cylinder combustion, supporting reliable cold start performance, smooth idle operation, restored engine power and reduced exhaust smoke when correctly matched to the engine arrangement. The unit is designed for demanding operating environments and is suitable for professional diesel engine repair workshops, fleet maintenance programs, remanufacturing operations and export spare parts distribution.

This injector fits the CAT 3116 engine platform across multiple applications, including CAT 910E, CAT 910F, CAT 928G, CAT 938F, CAT 938G, CAT 950F II, CAT 950G and CAT 962G wheel loaders, as well as CAT 3116 excavator, truck, marine engine, generator, industrial power unit, pump and compressor installations used in construction, mining and agricultural machinery. Related catalog coverage may extend to CAT 3114, CAT 3126, CAT 3126B and C7 family references; however, final compatibility must always be confirmed against the engine serial number, arrangement number, original injector part number, injector identification tag and the official parts catalog before installation.

Extensive cross reference coverage simplifies replacement sourcing, with interchangeable numbers including 127-8228, 127-8230, 0R-8465, 0R-8463, 0R-4103, 4P-1731, 4P-2995, 7E-8729, 7E-8727, 7E-8952, 7E-7607, 7E-6193, 7C-4567, 4W-6017, 9Y-4982, 101-4561, 101-8673, 102-7038, 102-7732, 102-7734, 105-1694, 107-1230, 107-7733, 107-7773, 127-8205, 127-8207, 127-8209, 127-8211, 127-8213, 127-8216, 127-8218, 127-8220, 127-8222, 127-8225, 140-8413, 162-0212, 162-0218, 173-4647, 0R-0471, 0R-3389, 0R-3580, 0R-4374, 0R-8461, 0R-8467, 0R-8469, 0R-8471, 0R-8473, 0R-8475, 0R-8477, 0R-8479, 0R-8483, 0R-8633, 0R-8682, 0R-8684, 0R-8867 and 10R-8996. To maximize service life, use clean diesel fuel, replace fuel filters on schedule, drain the water separator regularly and store spare injectors in sealed packaging, as fuel contamination remains the leading cause of injector failure.
