| No. | Question | Answer |
|---|---|---|
| Q1 | What core failure symptoms indicate the 180-7341 injection pump needs replacement? | Sudden power drop under heavy load, thick black exhaust smoke, hard startup, unstable idle speed, and obvious oil leakage at pump body oil ports are typical damage manifestations. |
| Q2 | Can this pump be directly installed on 3126 non-B engine without modification? | Partial early 3126 base engines need to match gear tooth number and ECU program; only 3126B full-series engines realize plug-and-play without adjustment. |
| Q3 | Why does the engine stall after replacing the 180-7341 pump? | The internal pressure regulating solenoid wiring plug is reversed, or the fuel filter sealing ring is not installed in place, leading to insufficient system oil pressure and flameout. |
| Q4 | How to maintain the service life of this HEUI high-pressure pump? | Strictly use high-standard diesel fuel, replace fuel filter regularly every 200 hours, avoid long-term idle operation, and prevent metal impurities from entering the pump body. |
| Q5 | Is the gear drive gear of 180-7341 interchangeable with other fuel pumps? | Exclusive 36-tooth gear matched for 3126B engine; gear parameters of C7/C9 engine fuel pumps are inconsistent and cannot be mixed. |
| Q6 | Does the pump need professional pressure calibration after installation on 325C excavator? | Factory complete pressure calibration, only need to complete 5-minute idle running after installation to automatically match the ECU fuel supply curve, no professional bench calibration required. |
| Q7 | What will happen if the high-pressure oil seal of the plunger fails? | Internal high-pressure diesel leaks into the engine crankcase, dilutes engine oil, causes lubrication failure, and may lead to engine cylinder pulling in severe cases. |
