22316750 Adapter | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta adapter used in selected TAD11 and TAD13 industrial diesel inlet-manifold, EGR and mixing-chamber assemblies. The adapter provides the correct connection or closure geometry within the charge-air and exhaust-gas-recirculation path, allowing the original V-clamp and sealing components to maintain a gas-tight joint.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1351-53VE
• Volvo Penta TAD1140-42VE

• Engine Family: TAD

⚙️ Key Features

• Genuine Volvo Penta OEM adapter
• Used within the inlet-manifold / EGR mixing-chamber assembly
• Correct machined sealing faces for the original clamp and O-ring arrangement
• Designed for hot charge-air and recirculated-exhaust-gas service
• Maintains the intended flow path and emissions-system integrity
• Installation position varies with engine and emissions specification
• Adapter only; clamp, O-ring, gaskets and adjoining housings are not included unless supplied separately

🔌 Function

Connects or closes the specified port in the inlet and EGR assembly while providing the correct sealing surface for the original clamp and O-ring. A sound adapter joint prevents loss of charge air and uncontrolled escape of hot recirculated exhaust gas.

⚠️ Common Signs of Failure

• Soot deposits around the adapter or clamp joint
• Hissing or exhaust-gas leakage under load
• Reduced power or delayed turbo response
• Boost-pressure or EGR-flow fault codes
• Damaged sealing face or distorted clamp lip
• Heat damage, corrosion or cracking
• Repeated O-ring or gasket leakage

🛠️ Service Notes

• Check the adapter against both of the parts it has to join before fitting — adapters are specific to an engine and its variant, and one that is close but not correct will not seat or seal properly
• Clean and inspect both mating faces or connector ends; grit, old sealant or corrosion on one side is the usual reason an adapted joint leaks or works intermittently
• Renew any O-ring, gasket or sealing washer belonging to the joint rather than reusing the old one, and lubricate rubber seals lightly so they slide into place instead of rolling or nipping
• Tighten threaded adapters to the figure given in the workshop manual for that connection; many go into aluminium or onto a soft seat and will distort if pulled up hard
• Where the adapter is a workshop tool, check it for thread wear and damage before use and never modify it to make something fit
