8-Rib Serpentine Belt for John Deere 6930-7530 Series with Air Conditioning and Air Brakes SKU: QT58679

When your cooling system belt fails during harvest or heavy fieldwork, you lose more than just airflow—you risk costly engine damage from overheating and dead electrical systems when the alternator stops charging. This belt ensures your A/C compressor, cooling fan, alternator, and hydraulic systems all operate reliably when you need them most.

Why This Belt Matters

• Each rib maintains precise contact with pulley grooves, maximizing power transfer while minimizing noise
• Modern EPDM construction resists the three main causes of belt failure: heat-induced cracking, stretching that causes loss of tension, and rib wear from continuous flexing
• The compound specifically resists glazing from A/C compressor cycling
• Multi-rib design distributes load evenly across pulleys, reducing vibration and extending component life
