About this part
4902827 is supplied as a remanufactured replacement fuel injection part. Cross-reference numbers: 4902827, 4902828, QSK23, QSK60. Application recorded for this part: Fits Cummins.
Fuel is delivered to this injector already pressurised by the rail. What it contributes is timing and atomisation — opening and closing within milliseconds, several times per combustion event on modern engines. Small changes in spray pattern or opening behaviour show up quickly as noise, smoke and rising consumption.
Typical signs are poor starting hot or cold depending on whether the unit is weeping or sticking, an idle that hunts or sounds uneven, smoke under acceleration, and sometimes a smell of diesel in the oil where an injector is leaking internally.
It costs little to confirm the diagnosis first. Compare return flow between cylinders and cut each injector in turn on a scan tool; if one cylinder makes no difference to running quality, that is your culprit.
Fitting notes: replace as a set rather than singly. A lone new injector will deliver differently from the worn ones around it, which usually reproduces the rough running. Use new sealing washers every time, clean the injector bore and seat carefully, and check whether your engine management expects classification codes to be entered after installation.
Rebuild process: full teardown and measurement first, then replacement of all wear components, machining back to specification where required, followed by calibration and bench testing. The difference between this and a cleaned used part is the measurement and test record — we hold every unit to the specification for the part number, not just to 'it runs'. Test sheets available on request, and every unit ships with a 12-month warranty.
