The Caterpillar 4P-9075 fuel injector, also referenced as 4P9075, 0R-3051, 0R3051, OR3051 and CA4P9075, is a heavy-duty diesel fuel injection component engineered for Caterpillar 3500 Series engines. It is widely applied in CAT 3512A, 3512, 3508, 3508C and 3516 engines powering generator sets, SR4 and SR4B power generation systems, marine propulsion units, mining machinery, oilfield engines and industrial power modules.
The injector meters, pressurizes and atomizes diesel fuel into the combustion chamber at the correct timing and quantity. When fuel pressure reaches the required level, the internal mechanism opens and releases diesel through precision-machined passages, atomizing it into fine particles that mix with compressed air for efficient combustion. Key advantages include precision fuel metering, stable injection performance, high-pressure atomization, wear-resistant internal components, industrial-grade durability and OEM-style fitment, supporting engine power, fuel economy and exhaust quality under continuous high-load conditions.
To maximize service life, operators should use clean diesel fuel, replace fuel filters on schedule, drain the water separator and monitor fuel pressure and exhaust smoke. Symptoms such as black or white smoke, hard starting, power loss, rough idle and high fuel consumption may indicate nozzle wear, poor atomization or fuel contamination. Before ordering, buyers should confirm the part number against the engine serial number, arrangement number and old injector photos; matched-set replacement is recommended for high-hour engines to improve fuel balance.
