21100930 Oil Line | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta pressurised turbocharger oil-supply line used in the TAD650VE turbocharger installation. This line occupies the feed position previously associated with pipe 20798726 and uses a hollow-screw and sealing-ring connection to deliver filtered engine oil to the turbocharger bearings. Even a small internal restriction can quickly damage the turbocharger.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD650VE
• Volvo Penta TAD660VE

• Engine Family: TAD
• Serial Range: SN5310377483-

⚙️ Key Features

• Pressurised turbocharger lubrication feed line
• Small controlled bore delivers filtered engine oil to the bearing housing
• Formed routing keeps the line clear of exhaust heat and vibration points
• Uses the specified hollow screw and sealing rings at the feed connection
• Must be replaced or thoroughly inspected after turbocharger oil-starvation failure
• Engine type: Inline-six turbocharged industrial diesel

🔌 Function

Supplies clean, pressurised engine oil to the turbocharger shaft bearings for lubrication and heat removal.

⚠️ Common Signs of Failure

• Turbocharger bearing noise or rapid shaft wear
• Low or absent oil flow at the turbocharger inlet
• External oil leakage at the banjo or flare connection
• Coked oil deposits restricting the line
• Turbocharger seizure shortly after installation when the old feed line is reused

🛠️ Service Notes

• Work clean and cap or plug both the line and its ports as soon as they are open — anything that gets into an oil line ends up at a bearing or in the turbocharger
• Renew the sealing washers, O-rings or gaskets at each end rather than reusing them, and start unions by hand so the seal is not loaded sideways
• Do not bend or reshape a line to make it reach; a line strained into place fatigues and cracks at the union
• Refit every clip and support bracket in its original position — an unsupported oil line chafes and fails through vibration
• After fitting, check oil level, run the engine and check the unions for leaks and the oil pressure for normal reading, then check again once hot
