# 21553364 Oil Line | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine lubricating-oil line used on Volvo Penta TAD650VE and TAD660VE industrial diesel engines.

## ⚙️ Key Features

-   TAD650VE and TAD660VE application
-   Factory-formed oil-line routing
-   Pressure- and temperature-resistant construction
-   Precision sealing connections
-   Updated replacement for line 21147527

## 🔌 Function

The line transfers lubricating oil between the assigned engine components while maintaining pressure and flow.

## ⚠️ Common Signs of Failure

-   Oil leakage around fittings
-   Cracked or chafed pipe
-   Damaged sealing surfaces
-   Restricted oil flow
-   Oil-pressure loss

## 🛠️ 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
