⚙️ Key Features

• Genuine Volvo Penta 8PK1330-Class V-Ribbed Belt - part number 20860660
• 8-rib Poly-V construction for wide contact area
• Approximately 1327-1331 mm effective-length class
• Engine-specific length and rib alignment

• Pulley grooves must be clean, undamaged and free from oil or coolant
• Engine type: D5/D7-series Volvo Penta industrial diesel applications

🔌 Function

The belt drives the engine's configured accessories from the crankshaft. The multi-rib surface shares load across eight ribs, allowing reliable drive through compact pulley centres while the tensioner absorbs transient movement.

⚠️ Common Signs of Failure

• Glazing and squeal during acceleration
• Outer ribs worn more heavily than inner ribs
• Belt walks off the pulley or frays at an edge
• Cracks reach the tensile cord or ribs separate
• Accessory output drops because the belt slips

🛠️ Service Notes

• Fit the belt over the pulleys by hand and let the tensioner take it up — never lever a ribbed belt on with a screwdriver, which cracks the rib flanks and shortens its life
• Check that every rib sits in its pulley groove and that the belt runs central on each pulley before cranking the engine
• Inspect the tensioner and every pulley face while the belt is off; a rough bearing, a rusty tensioner arm or a scored pulley will destroy a new belt
• Note the routing before removal, then turn the engine over by hand once the new belt is on and re-check the run and tension following the procedure for your engine
• Keep oil, fuel and coolant off the belt, and renew a contaminated belt rather than trying to clean it
