978515 V-Belt | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta v-belt for engines up to serial number 1025582, weighing 0.091 kg and listed for eight applications across TD and TAD engines. The serial cut-off is what decides it — an engine built after that number takes something else. It supersedes 20701268 and 966916, one of which was catalogued earlier simply as a belt.

Carries drive from the crankshaft pulley to an engine-driven accessory such as the alternator or a circulation pump.

⚠️ Common Signs of Failure

• Squealing from the front of the engine on start-up or under load
• Charge warning light flickering, or the alternator falling behind
• Cracks across the back of the belt, or glazed and shiny flanks
• Black belt dust building up under the pulleys
• Belt turned over in the groove or thrown off the pulley

🛠️ Service Notes

• Check the engine serial number before ordering — this belt is listed only up to 1025582
• Belt 978547 shares this exact published weight of 0.091 kg on a wider TWD, TD and TAD fitment, so the two cannot be told apart by mass
