093400-6420 is supplied as a remanufactured replacement injector. Cross-reference numbers: 093400-6420, DLLA154P642. In a common rail system the injector is the component that actually controls combustion. It holds back fuel at rail pressure and lifts for only a few milliseconds at a time, metering the exact quantity and breaking it into a fine spray so the charge ignites cleanly. When delivery drifts, the engine does not usually stop — it simply starts to burn fuel badly. 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. Because those symptoms also point to compression, turbocharger or air-side problems, it is worth confirming before ordering. A return-flow (back-leakage) test across all injectors and a cylinder cut-out test will usually identify both whether the fault is injector-related and which cylinder is responsible. 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.
