170-9074 Aftermarket HEUI Fuel Injector for Ca-terpillar 3126B Diesel Engines
170-9074 Fuel Injector is an aftermarket-listed hydraulic electronic unit injector (HEUI) for selected Ca-terpillar 3126B diesel engine applications. It uses high-pressure engine oil and electronic control to pressurize, meter and inject fuel accurately, supporting stable combustion and reliable engine power.
It is marketed for selected medium-duty trucks, construction machinery and industrial equipment powered by compatible 3126B engines. Please verify the injector number, engine serial number, arrangement number and equipment model before ordering.
Some aftermarket suppliers use 170-9074 as a 3126B injector reference; however, Cat’s official catalog identifies this number as a different component. Compatibility must therefore be confirmed using the supplier catalog and physical injector specifications. Professional installation and calibration are recommended.
.Manufactured with wear-resistant precision components and a reliable sealing structure, this injector withstands continuous vibration and demanding working conditions. It helps address hard starting, unstable idle, power loss, excessive fuel consumption and black smoke.
Every Fuel Injector we supply undergoes professional bench testing. Injection quantity, spray pattern, sealing performance and operating stability are inspected to ensure reliable fuel delivery and consistent engine performance.
Q1: What is the 170-9074 Fuel Injector?
A: The 170-9074 is an aftermarket-listed HEUI hydraulic electronic unit injector reference used by some suppliers for selected Ca-terpillar 3126B diesel engines.
Q2: What equipment uses 170-9074?
A: It is marketed for selected medium-duty trucks, construction machinery and industrial equipment powered by compatible Ca-terpillar 3126B engines. Please verify the engine serial number and equipment model before ordering.
Q3: What are the cross-references for 170-9074?
A: No official injector cross-reference has been confirmed for this number. Compatibility must be verified using the physical injector number, engine serial number, arrangement number and calibration specifications.
Q4: Does 170-9074 require electronic programming?
A: Electronic programming is not always required. However, the ECM injector calibration settings should be checked, and installation must follow the applicable engine service manual.
Q5: Is the injector tested before shipment?
A: Yes. Each supplied injector is professionally bench-tested for fuel delivery, injection response, sealing performance and operating stability before shipment.
Q6: Is 170-9074 available new or remanufactured?
A: We can supply new aftermarket and remanufactured options, subject to compatibility confirmation and stock availability. All supplied injectors include a 12-month warranty.
Important: Cat’s official catalog identifies 170-9074 as a different component rather than a fuel injector. Confirm the physical product specifications before ordering.
