1194359 Muffler | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta exhaust muffler used on selected Volvo B10 and B10M heavy-duty diesel installations. The large silencer reduces exhaust noise while maintaining the gas-flow capacity required by the turbo-diesel engine. The assembly is approximately 990mm long and belongs to the 1194359 / 347057 silencer family. Exhaust inlet, outlet, bracket position and overall dimensions should be matched to the original unit before installation.

🚤 Compatibility

• Year Range: Approximately late 1970s - 1990s

⚙️ Key Features

• Genuine Volvo Penta heavy-duty exhaust silencer
• Correct Volvo Penta part number 1194359
• Designed for Volvo B10 / B10M diesel exhaust systems
• Large-capacity construction for commercial bus and coach operation
• Engine type: Volvo inline 6-cylinder naturally aspirated or turbocharged diesel

🔌 Function

The muffler attenuates exhaust pressure pulses and combustion noise while routing exhaust gases safely away from the engine and passenger compartment.

⚠️ Common Signs of Failure

• Exhaust becomes noticeably louder
• Soot or fumes escape from cracks or corroded seams
• Internal baffles rattle or restrict exhaust flow
• Backpressure increases and engine performance falls
• Mounting points, inlet or outlet pipes become fractured or heavily corroded

🛠️ 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
