1549407 Hub | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta hub is a centred rotating-drive or coupling component used in the crankshaft vibration-damper mounting. It is manufactured to the original Volvo Penta dimensions and interface requirements so the driven component remains concentric, aligned and securely coupled. In service, it centres and drives the crankshaft-mounted vibration damper at the front of the engine. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1549407 against the installed assembly before ordering.

🔌 Function

The hub provides the machined mounting and centring interface that carries a driven component on a rotating shaft and transmits torque between the two. It keeps the attached assembly concentric and correctly aligned during engine operation.

⚠️ Common Signs of Failure

• Vibration or wobble caused by run-out from a worn or distorted hub
• Cracking or elongation around the bolt holes and mounting face
• Wear or fretting on the shaft bore leading to a loose fit
• Corrosion or scoring on the mating surfaces
• Repeated loosening of fasteners or an audible knock from the drive assembly

🛠️ Service Notes

• Get the hub off with the correct puller rather than levering or hammering it; a hub driven off or on is enough to damage the shaft, the bearing behind it and the hub itself
• Clean and inspect the shaft, keyway or taper and check for scoring, wear steps and fretting; a hub will not run true on a damaged seat and the fault will come straight back
• Inspect and renew the seal that runs on or behind the hub while access is good, and check the sealing surface for a wear groove
• Draw the hub on square, fully home to the position the workshop manual for your engine gives, and tighten the retaining fastener to the manual figure with any specified locking method
• Check the drive belt alignment and run-out after fitting, then run the engine and watch for wobble, noise or a belt tracking off to one side
