99476929 is supplied as a remanufactured replacement nozzle. Cross-reference numbers: 99476929, 5000658957, 3256575. This part works at the sharp end of the injection system — high pressure, tight clearances, direct exposure to combustion heat. Nozzle condition governs how well fuel atomises, and therefore how much of it contributes to power rather than leaving as smoke. Nozzle faults usually show as poor atomisation: smoke that will not clear, hard starting, rough combustion, higher consumption, and heavy carbon around the tip when it is removed for inspection. Before ordering, check whether the fault really originates here. Poor spray often starts upstream — supply pressure, contamination, or a high-pressure pump no longer delivering — and replacing only the nozzle leaves the cause in place. Cleanliness decides the outcome here. Work with the bore and seat scrupulously clean, fit new copper washers and seals, torque to specification, and check whether the engine needs injector coding after reassembly. 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.
