⚙️ Key Features

• Genuine Volvo Penta OEM vibration damper
• OEM part number 20546792
• Technical distinction: Crankshaft torsional vibration damper, 248 x 32 mm
• Inspect the mating shaft/key/spline, install with the correct press or puller method, align belt/gear tracks and verify run-out and fastener torque.

🔌 Function

Absorbs crankshaft torsional vibration and protects the crankshaft, gears and accessory drive from damaging resonance. Inspect the mating shaft/key/spline, install with the correct press or puller method, align belt/gear tracks and verify run-out and fastener torque.

⚠️ Common Signs of Failure

• Abnormal torsional vibration, rattling or cyclic noise
• Pulley, flywheel or hub run-out and belt-tracking problems
• Cracking, wear or damage at the hub, spokes or mounting face
• Loose fasteners, fretting or damaged key/spline interface
• Accessory-drive, starting or timing problems caused by misalignment

🛠️ Service Notes

• Treat the damper as a sealed assembly — it is not repairable, and nothing about it should be straightened, re-bonded or adjusted
• Renew it if the rubber is cracked, swollen, oil-soaked or has moved relative to the hub, and whenever the engine has been run with a known torsional or vibration problem
• Fit to clean, dry, undamaged mating faces, tightening the fasteners in the sequence and to the figures given in the workshop manual for your engine
• Use new bolts wherever the manual calls for them; the loading here is cyclic and a reused or stretched fastener is a poor risk
• While access is good, check the components it drives or couples to, and their alignment — a damper rarely fails for no reason
