978489 V-Belt Set | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta v-belt set, 875 mm long, weighing 0.132 kg and listed for four applications across TAD engines. The 775 mm set 978467 covers the same four applications and is published 11 g heavier despite being the shorter set, so length is the only thing that should decide the order.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD720VE
• Volvo Penta TAD721VE
• Volvo Penta TAD722VE
• Volvo Penta TAD520VE

• Engine Family: TAD

⚙️ Key Features

• 875 mm long
• Supplied as a set, not as a single belt
• Fits four applications across TAD engines
• 0.132 kg
• L=875mm (Volvo assembly listing)

🔌 Function

Drives an accessory off the crankshaft, supplied as a set so the belts running together are all renewed at the same time.

⚠️ Common Signs of Failure

• Squealing from the front of the engine on start-up or under load
• One belt visibly slacker or running deeper in its groove than its neighbour
• Cracks across the back of a belt, or glazed and shiny flanks
• Black belt dust building up under the pulleys
• Charge warning light flickering, or the alternator falling behind

🛠️ Service Notes

• Order by the 875 mm length — the published weights of the two TAD sets run the opposite way to their lengths
• Do not fit a new belt alongside an old one from the set; the fresh belt takes almost all the load

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
