3580804 Key | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta key for older propeller shafts, from the Marine Propulsion group, weighing 0.026 kg. It measures 8 mm by 10 mm across, 3.5 mm and 6 mm in height and 58 mm long, and suits a 30 mm shaft. The accessories catalogue introduced these keys so that older shafts with a 10 mm key slot can take the new ISO standard bronze propellers - that is the reason the part exists, and it is the smaller of the two sizes listed, with 3580805 covering 40 mm shafts.

Locates the propeller or hub to its shaft so drive is transmitted without slip.

⚠️ Common Signs of Failure

• Key sheared, allowing the hub to slip on the shaft
• Keyway in shaft or hub worn or burred
• Key a loose fit in the slot
• Hub found to have moved on the shaft

🛠️ Service Notes

• Both the key dimensions and the 30 mm shaft diameter must match, so measure the shaft and keyway before ordering
• A sheared key usually means the hub was loose, so check the taper or clamping arrangement, not just the key
