{"product_id":"1664910-fan-ring-genuine-volvo-penta","title":"1664910 Fan Ring | Genuine Volvo Penta Part","description":"\u003ch2\u003e\n 🔧 Product Description\n\u003c\/h2\u003e\n\u003cp\u003e\n This genuine Volvo Penta fan ring is a cooling-airflow control ring used in the 750 mm suction-fan ring\/shroud. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. Nominal fan-ring diameter: 750 mm. In service, it controls airflow around the suction fan and reduces recirculation between the hot and cold sides of the radiator. Selection must be confirmed by OEM part number 1664910, the exact engine\/product model, serial number and the installed assembly configuration.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  TAD, TD, TWD\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\n Full model list at the end of this description.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Volvo Penta OEM part number 1664910\n \u003c\/li\u003e\n \u003cli\u003e\n  Fan ring diameter: D=750mm\n \u003c\/li\u003e\n \u003cli\u003e\n  System group: Cooling System\n \u003c\/li\u003e\n \u003cli\u003e\n  Net weight approximately 3.02 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Supersedes earlier fan rings 1664483 and 476807 (which in turn replaced 476578)\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits TD, TID, TWD and TAD series industrial and generator-set diesel engines\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n The fan ring forms a shroud around the cooling fan, closing the gap between the fan blade tips and the radiator so that airflow is drawn through the radiator core rather than recirculating around it.
