22056196 Muffler | Genuine Volvo Penta Part

🔧 Product Description

Exhaust silencer for the vertical-outlet SCR installation on TAD1170-TAD1172VE engines. The housing is sized to control noise without exceeding the engine's allowable exhaust back pressure.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1170-72VE

• Engine Family: TAD

⚙️ Key Features

• Reduces exhaust sound pressure
• Flow area matched to engine back-pressure limits
• High-temperature corrosion-resistant construction
• Original inlet/outlet orientation and support points
• Emissions-package and installation controlled

🔌 Function

Attenuates exhaust noise while carrying exhaust gas within the allowable back-pressure limit.

⚠️ Common Signs of Failure

• Exhaust leakage or soot staining
• Internal baffle rattle or collapse
• Excessive exhaust back pressure
• Corrosion, cracking or perforation
• Higher exhaust noise than normal

🛠️ Service Notes

• Carry the muffler on its own mountings so that its load is taken by the structure and not by the exhaust hose, pipework or the turbocharger outlet
• Fit it the right way round and to the correct fall — these units are directional, and the run must let water drain away and never allow it to run back towards the engine
• Use two corrosion-resistant clamps on each wet exhaust hose joint, staggered so the screw housings are not in line, and check the hose ends are clean, sound and pushed fully home over the spigot
• Check the whole exhaust run and its hangers while the muffler is out — old soot, water staining or a sagging hose downstream tells you why the last one failed
• Where a drain plug is fitted, use it to drain the unit for winter layup, and check for leaks and unusual noise once the engine has been run and the system is hot
