0445120330 is supplied as a remanufactured replacement injector assembly. Cross-reference numbers: 0445120330. This is the last precision component in the fuel path. Everything upstream exists to deliver clean fuel at stable pressure; this unit decides when combustion starts and how completely the charge burns. That is why injector condition shows up so directly in noise, smoke and emissions. Symptoms that point to injector wear include hard starting when hot, rough idle, white smoke at start-up or black smoke under load, a sharp knocking from one cylinder, increased fuel consumption and a gradual loss of power. 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. How we build it: the unit is fully disassembled, cleaned and measured, not simply resealed. Wear items — seals, springs, and where clearance is out of specification the plunger and barrel or nozzle assemblies — are replaced rather than reused. Sealing faces and bores are re-machined back to original clearances, then the unit is calibrated and run on a bench with delivery, return flow, opening pressure and leakage recorded. Anything outside specification does not ship. Test sheets for your specific units are available on request. Covered by a 12-month warranty.
