8-Rib Serpentine Fan Belt for John Deere 6810/6910/6910S Tractors SKU: QT59540G

When your serpentine belt starts squealing, slipping, or showing cracks, it's signaling trouble ahead—a broken belt means no water pump circulation, rapid overheating, and a dead alternator that leaves you stranded in the field. This 8-rib serpentine belt restores reliable operation of your cooling fan, alternator, and hydraulic pumps to keep your tractor running through demanding operations.

Why This Belt Matters

• Precise 8-rib design provides maximum grip and smooth power transfer across all pulleys
• Modern EPDM construction resists surface cracking from heat exposure and tension loss from stretching
• Each rib maintains precise contact with pulley grooves for quiet operation and maximum efficiency
• Heat- and oil-resistant compound handles the punishment of continuous field operation

Professional installation is recommended—use manufacturer-specified tools to safely release the tensioner and follow the routing diagram exactly. While the belt is off, inspect all pulleys for wear and clean debris from grooves to ensure proper seating. This belt is designed for tractors without air conditioning and air brake systems, providing the exact fit your equipment needs for reliable cooling and electrical system operation.
