4720700887 is supplied as a remanufactured replacement injector. Cross-reference numbers: 4720700887, 0445120270, 0445120303, 0986435624. An injector is a high-speed valve. It has to hold back rail pressure, then open and close within a fraction of a crankshaft degree — several times per cycle on pilot-injection engines. Anything that alters opening behaviour, whether it is carbon on the tip, a worn needle or a tired solenoid, changes how the cylinder burns its charge. 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. 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. Installation notes: new copper washers and seals are mandatory, the seat must be clean and undamaged, and the retainers should be torqued to the engine manufacturer's specification. If the ECU stores injector codes for this engine, program them after fitting, otherwise the engine will not compensate correctly. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
