1543723 Nozzle | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta injector nozzle from the Engine system group, serving the fuel injection system on the 16-litre TAMD, TWD, TAD and TID series marine and industrial diesel engines. It atomises pressurised fuel into the combustion chamber for each cylinder, making it a key wear item in maintaining rated power, clean combustion and fuel economy. Nozzles are normally inspected, tested and replaced as a matched set across all cylinders.

🚤 Compatibility

• Engine Family: TWD, TID, TD, TAMD, TAD
• HP Range: Approximately 468-770 HP
• Year Range: Approximately 1987-2005

🔌 Function

The nozzle is the final element of the injector, spraying precisely metered high-pressure diesel into the cylinder in a defined atomised pattern. Correct spray geometry and opening pressure are essential for complete combustion, rated power output and low exhaust smoke.

⚠️ Common Signs of Failure

• Black or grey exhaust smoke and rising fuel consumption
• Rough idle, misfire or uneven cylinder running
• Hard starting or noticeable knocking/diesel rattle under load
• Loss of power and inability to reach rated RPM
• Dripping or coked nozzle tip found during injector pop testing

🛠️ Service Notes

• Work scrupulously clean — a nozzle is a precision component with fine machined orifices, and grit carried in on a fingertip or a rag is enough to ruin it
• Never poke, ream or wire-brush the holes or the seat; if a nozzle is blocked or its spray pattern is disturbed, renew it
• Cap or plug the open fuel or oil way while the nozzle is out so nothing can drop into the passage
• Fit new sealing washers, seals or O-rings, clean the seat in the housing and check that seat is undamaged before the nozzle goes back
• Tighten to the figure and sequence given in the workshop manual for your engine; a nozzle pulled down unevenly or over-tightened will distort and leak
