# 3849102 Weld Flange | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta 8 inch weld flange from the Inlet and Exhaust System group, weighing 4.89 kg and listed for 5 applications across TWD-series engines. The 8 inch size is the deciding detail, and the flange is designed to be welded to the pipe rather than clamped on.

-   Volvo Penta TWD1643GE
-   Volvo Penta TWD1652GE
-   Volvo Penta TWD1653GE
-   Volvo Penta TWD1644-45GE
-   Volvo Penta TWD1663GE

-   **Engine Family:** TWD

## ⚙️ Key Features

-   8 inch
-   4.89 kg
-   Welded joint, not a slip fit
-   5 applications across TWD-series engines
-   2 used per assembly

## 🔌 Function

Provides the bolted joint face at the end of an exhaust section once welded to the pipe.

## ⚠️ Common Signs of Failure

-   Soot leaking from the flange joint
-   Weld cracked around the pipe where it meets the flange
-   Flange face pitted, scaled or distorted so a gasket will not seal
-   Bolt holes corroded or the fixings seized
-   Exhaust noise or fumes appearing at the joint

## 🛠️ Service Notes

-   This is a welded component - fitting needs proper welding equipment and a competent welder, and the flange must be set square to the pipe or the joint will never seal
-   It pairs with the other 8 inch parts here: pipe elbow 3849029, exhaust pipe 3849093 and gasket 3849220
-   Renew the joint gasket and the fixings, and let the exhaust cool fully before starting work
