🔧 Product Description

Heat shield used around the HE600WG turbocharger installation on TAD1643VE and TAD1643VE-B engines. It protects nearby hoses, wiring and structure from turbine-housing and exhaust heat.

⚙️ Key Features

• Exact TAD1643VE/TAD1643VE-B turbo area
• Matched to turbocharger 22283878
• Formed radiant-heat barrier
• Maintains protective air gap
• High-temperature mounting hardware
• Engine type: 16-litre 6-cylinder turbocharged industrial diesel
• Also supersedes Volvo part number 20750729

🔌 Function

Reduces radiant heat from the turbocharger and protects surrounding electrical, air and cooling components.

⚠️ Common Signs of Failure

• Cracked or loose shield
• Rattling against turbo or exhaust
• Heat damage nearby
• Distorted shield
• Missing mounting hardware

🛠️ Service Notes

• Fit heat shields before anything else is routed near the exhaust, and check there is clear air space between the shield and every hose, cable, fuel line and belt
• Renew any insulation, gaskets, spacers or standoffs supplied with the shield; a shield clamped flat onto a hot surface loses much of its effect
• Tighten the fixings evenly and only to the figure in the workshop manual for your engine — the tabs and brackets are thin and distort easily
• Never run the engine with a shield missing or loose: bare exhaust surfaces are a fire risk in an engine space and a burn risk to anyone working alongside
• Check the shield and its fasteners whenever the exhaust is disturbed, as vibration works them loose and a rattling shield soon cracks at its mounting tabs
