⚙️ Key Features

• 13.880 kg
• 24 applications on D series engines
• Marine Propulsion group
• Heavy coupling component

🔌 Function

Bolts to the mating flange to couple the shaft to the drive, transmitting the full thrust and torque through the joint.

⚠️ Common Signs of Failure

• Vibration through the hull that rises with shaft speed
• Bolt holes worn oval, or bolts found loose or sheared
• Face run-out so the flanges will not pull up square
• Corrosion or fretting rust on the mating faces
• Cracks radiating from a bolt hole or the hub

🛠️ Service Notes

• At 13.880 kg this is a heavy item - arrange support before you break the coupling
• Check flange face run-out and shaft alignment after fitting; a new flange on a misaligned shaft will vibrate and fail again
• Renew the coupling bolts and locking hardware rather than reusing them

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
