The YNF17304 3914458 pulley is engineered for the 6D102 diesel engine, widely used in excavators and heavy machinery. Its 4-hole mounting pattern and 8-groove belt interface guarantee precise alignment and stable power transfer to engine accessories such as the alternator, water pump, and fan system.
Manufactured from high-strength steel and machined to tight tolerances, the pulley provides excellent resistance to wear, belt slip, and high-temperature operation. The multi-groove design improves belt grip, reduces vibration, and ensures long-term reliability under continuous working conditions.
This pulley is an OEM-equivalent replacement, preferred by machine repair centers, engine rebuild shops, and aftermarket distributors requiring durable and cost-effective belt drive components. YNF Machinery ensures consistent quality and stable supply for global buyers.
