## ⚙️ Key Features

-   For TWD740G, Alt
-   0.488 kg
-   3 applications across TWD and TAD series engines
-   Inlet and Exhaust System crankcase breather pipework

## 🔌 Function

Carries crankcase breather gas away from the engine to its connection point so crankcase pressure stays low and oil is not forced past the seals.

## ⚠️ Common Signs of Failure

-   Oil misting or wet oil around the breather route
-   Oil pushed past seals or the dipstick as crankcase pressure builds
-   Pipe blocked, sludged or partly frozen with deposits
-   Pipe cracked, chafed or split
-   Oil consumption climbing with no external leak

## 🛠️ Service Notes

-   Confirm the engine designation is TWD740G and that the Alt version is the one required before ordering
-   Clear the breather route completely — a partly blocked breather raises crankcase pressure and makes seals leak
