John Deere Viscous Fan Clutch - Part Number: 74712312

The Viscous Fan Clutch (part number 74712312, original John Deere OEM reference RE164619 and cross-reference 8521137) is a high-precision thermodynamic fan drive designed to modulate radiator fan speed continuously in response to engine operating temperatures. It ensures maximum cooling performance while drastically minimizing parasitic engine drag across heavy-duty wheeled and tracked John Deere 8020 and 8020T Series tractors.
Key Features & Benefits
  • Automated Thermal Regulation: Thermosensitive internal silicone fluid modulates torque transfer to the fan blade only when required, stabilizing engine coolant temperatures within ideal limits.
  • Fuel Efficiency & Drag Reduction: Eliminates continuous fan load during lower temperature operations, improving fuel efficiency and reducing engine bay noise.
  • Heavy-Duty Agricultural Architecture: Engineered with heavy-duty bearing assemblies and durable seals capable of handling high vibration, heat cycling, and abrasive field dust.
  • Exact Direct OEM Fitment: Manufactured to match original John Deere RE164619 bolt patterns, dynamic balance requirements, and mounting dimensions.
