7420542693 Renault Fan Ring
Engineered for RENAULT TRUCKS and VOLVO commercial vehicles (1993-2021), the 7420542693 Renault Fan Ring (7420542693, 3979735, 20441083) features laser-cut stainless steel reinforcement ribs with 0.12mm concentric tolerance. The triple-layer epoxy coating withstands 500+ thermal cycles between -30°C and +130°C. Precision-engineered mounting holes align with 20441102 fan shrouds and 3979740 hub assemblies. The aerodynamic vaned design reduces turbulence by 22% compared to traditional models, while maintaining compatibility with RENAULT Kerax/Premium and VOLVO FH/FM series cooling systems through 2021 model years.
Engineering Specifications
Designed with 8-stage CNC-machined aluminum alloy (EN AW-6082), the fan ring maintains 0.05mm radial runout tolerance across its 420mm diameter. The corrosion-resistant zinc-nickel plating exceeds ISO 9227 salt spray test requirements (720hrs). Integrated alignment notches ensure precise positioning with 20441085 radiator assemblies. The dynamic balancing system reduces vibration levels below 0.8mm/s RMS at 2500 RPM operational speeds. All fastening points use M10x1.5 threaded inserts compatible with 3979738 bolt kits.
