## ⚙️ Key Features

-   0.034 kg
-   Supersedes 20450891 and covers its 45 applications across D, TD, TAD and MD series engines
-   One current number covering a broad older fitment

## 🔌 Function

Seals a machined port or passage so fluid stays in and dirt stays out, and can be removed for draining or service access.

## ⚠️ Common Signs of Failure

-   Weeping or a damp film around the plug
-   Fluid level falling with no obvious external leak
-   Drive socket or hex rounded off by an earlier removal
-   Plug seized or corroded into the housing
-   Sealing washer found flattened, hardened or missing

## 🛠️ Service Notes

-   Renew the sealing washer or o-ring whenever the plug is removed, and clean the seat before refitting
-   Tighten to seal rather than to the limit, since the housing thread will give way before the plug does
