FAQ 


Q1: What are the main fault codes (DTCs) in English when this injector fails on a Komatsu PC200-8 excavator?

When a Komatsu excavator or Cum-mins QSB5.9 engine experiences trouble with this injector, operators will usually see an engine warning light, and the English diagnostic tool (like Komatsu INSITE or Cum-mins INSITE) will trigger these codes:

  • Misfire / Fault Codes: E015 or CA559 (Common Rail Pressure Low - indicating an injector is stuck open or leaking internally).

  • Electrical Faults: CA2249 / CA271 (Injector Circuit Fault - indicates electrical short or open circuit in the solenoid coil).

  • Engine Performance Terms: "Engine Hunting" , "White Smoke on Cold Start" , or "Loss of Engine Power" 

Q2: Is there any difference between 0445120151 and 0445120239?

No. They are 100% interchangeable.

  • The Relationship: Bos-ch part number 0445120239 is the direct factory supersession  for 0445120151.

  • In the Market: Bos-ch updated the internal design slightly to improve durability against poor fuel quality. If a customer orders a 151 injector, it is perfectly standard and accepted in global trade to supply them with a 239 injector instead.

Q3: Why do Komatsu excavators frequently experience premature wear on this specific injector model?

In the global mining and construction sectors, this injector's internal control valve (F00RJ02130) is highly sensitive to two major factors:

  1. Fuel Contamination (Micro-particles): Excavators operate in highly dusty environments. If dust or moisture passes through the fuel filters, it cuts into the valve seat like sandpaper.

  2. High Back-Leakage (Excessive Return Flow): Once the valve seat is scratched, fuel escapes back through the return line. The excavator will become very difficult to start when the engine is hot, but might still start normally when cold.

Q4: Does the Cum-mins QSB5.9 / Komatsu 6D107 engine require coding after installation?

No, this specific model does not require software IMA coding. Unlike passenger car injectors or newer generation truck injectors, the 0445120151 belongs to an older heavy-duty generation that relies heavily on mechanical balancing. After replacing the injectors, you do not need to input a code into the ECM. The engine's computer will automatically recalibrate using its cylinder balancing parameters after running for a brief period.
