## 🔧 Product Description

Genuine Volvo Penta tab washer for the TAD1630V, weighing 0.009 kg and listed for 6 applications across the TWD and TAD series. The engine designation is what separates it from other locking washers, so order it against that engine.

## ⚙️ Key Features

-   For the TAD1630V
-   0.009 kg
-   Listed for 6 applications across the TWD and TAD series
-   Single-use mechanical lock
-   3 used per assembly

## 🔌 Function

Locks a nut or bolt mechanically - a tab is bent up hard against a flat of the fastener so it cannot rotate loose.

## ⚠️ Common Signs of Failure

-   Fastener found loose with its locking tab flattened out
-   Tab cracked or broken off at the bend
-   Washer dished or distorted under the fastener head
-   Corrosion between washer and component, so the tab breaks up on removal

## 🛠️ Service Notes

-   Single use - a tab bent once has already work-hardened and will crack if bent again
-   Bend the tab against a flat of the fastener, not a corner, and check clearance to anything rotating nearby
