⚙️ Key Features

• Bellows from the Inlet and Exhaust System group
• 0.647 kg
• Supersedes 3584167, catalogued earlier as an exhaust hose
• Listed for five D series engine applications

🔌 Function

Absorbs movement, expansion and vibration in the exhaust run so the flexing is taken by the bellows rather than by the pipework and its joints.

⚠️ Common Signs of Failure

• Exhaust noise, fumes or soot marks where the bellows meets the pipe
• Convolutions split, torn or blown open
• Bellows over-stretched, crushed or set to one side
• Corrosion and scaling in the folds
• Cracks appearing in the pipework nearby because the bellows has stiffened

🛠️ Service Notes

• The earlier number was catalogued as an exhaust hose, so an older parts list may describe the same position differently
• Check the alignment and support of the pipe run before fitting - a bellows that is taking misalignment rather than movement will fail again
• Renew the clamps or gaskets at both ends with the bellows
