859614 Pulley | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta pulley, listed as the alternative for the AD41D, from the Engine group, weighing 4.010 kg and covering 33 applications across the TAMD, AD, D, TMD, KAD and KAMD series. It supersedes part number 838725, which the earlier lists catalogued as a vibration damper — so the old number and the current one are described differently, and it is worth confirming what your engine actually needs before ordering.

🚤 Compatibility

• Engine Family: TAMD, AD, D, TMD, KAD, KAMD

⚙️ Key Features

• Listed as the alternative for the AD41D
• Supersedes 838725, catalogued earlier as a vibration damper

🔌 Function

Drives the auxiliary belts from the crankshaft, transmitting the drive to the alternator and the pumps.

⚠️ Common Signs of Failure

• Belt squeal, belt dust, or belts that will not stay in tension
• Visible wobble or run-out at the pulley with the engine running
• Belt grooves worn shiny, stepped or with the belt sitting low in them
• Rubber element perished, cracked or visibly shifted where one is fitted
• Timing marks that appear to have moved relative to the crank

🛠️ Service Notes

• Check the AD41D alternative note against your engine before ordering, and confirm whether your installation needs the damper or the pulley
• Renew the belts when the pulley is changed and set tension to your engine's figure
• Tighten the crankshaft fastener to the specified torque and angle — this joint is highly loaded and must not be guessed at
