21493933 Exhaust Pipe | Genuine Volvo Penta Part

🔧 Product Description

A rigid exhaust-system pipe used on selected Volvo Penta TAD7 industrial diesel engines. The pipe forms part of the manifold and turbocharger-side exhaust arrangement, carrying high-temperature exhaust gas through a sealed, correctly aligned connection while withstanding vibration and repeated heat cycling.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD752GE
• Volvo Penta TAD753GE
• Volvo Penta TAD765VE
• Volvo Penta TAD764VE
• Volvo Penta TAD763VE
• Volvo Penta TAD762VE
• Volvo Penta TAD761VE

• Engine Family: TAD
• HP Range: Approximately 200-330 HP
• Year Range: Approximately 2007 - 2021

⚙️ Key Features

• Genuine Volvo Penta high-temperature exhaust pipe
• Correct factory shape and flange alignment
• Designed for the specified TAD7 industrial engine exhaust arrangement
• Supports a sealed exhaust path and correct turbocharger gas flow
• Direct replacement for a cracked, distorted or leaking original pipe
• Engine type: 7.15L inline six-cylinder turbocharged industrial diesel

🔌 Function

Transfers exhaust gas between the manifold, turbocharger and downstream exhaust components while maintaining gas velocity, alignment and a sealed high-temperature joint.

⚠️ Common Signs of Failure

• Black soot around a flange, joint or crack
• Exhaust hissing or ticking that increases under load
• Exhaust fumes or excessive heat in the engine compartment
• Reduced turbocharger response, boost or engine power
• Visible cracking, distortion or failed gasket surfaces

🛠️ Service Notes

• Fit new gaskets and seals at every joint you disturb; exhaust gaskets take a set once they have been heat-cycled and will not seal a second time
• Clean the flange faces back to bare, flat metal and check them for distortion and pitting — a warped face will blow out a new gasket however hard it is pulled up
• Renew corroded studs and nuts, use a high-temperature anti-seize on the threads, and tighten in the sequence and to the figures in the workshop manual for your engine; recheck once the engine has been run up to temperature and allowed to cool, because the joint relaxes over the first few heat cycles
• Support the pipe on its own mountings so nothing hangs on the flange and no hose pull is taken through the joint, and keep the specified clearance to hoses, wiring and glassfibre
• On water-cooled sections, check the cooling passages are clear and the water connections sound before running — a restricted jacket will cook the pipe and the hose behind it
