⚙️ Key Features

• Supersedes 421515, catalogued earlier as a vibration damper
• 11.473 kg
• Engine group
• 24 applications across four engine series

🔌 Function

Absorbs the torsional pulses in the crankshaft so they are not passed on to the gear train and driven equipment.

⚠️ Common Signs of Failure

• A new, deeper vibration through the hull or mounts at certain speeds
• Rubber element cracked, swollen or standing proud of the hub
• Timing marks on the outer ring no longer lined up with the hub
• Rumble or drone that was not there before
• Repeated failures of belts, brackets or accessories driven off the front

🛠️ Service Notes

• Anyone searching for the old vibration damper number 421515 should be sent to this part
• At 11.473 kg it needs supporting on removal, and the crankshaft bolts should be renewed and torqued in sequence
• A damper that has lost its element takes brackets and pulleys with it, so inspect the front-end drive components at the same time
