Full model list at the end of this description.

## ⚙️ Key Features

-   Correct thread and sealing profile
-   Replace if threads or sealing face are damaged
-   Direct replacement where part number 21235758 is specified
-   Engine type: TAD11 inline-six turbocharged industrial diesel

## 🔌 Function

Closes and seals a lubrication passage in the oil-filter housing.

## ⚠️ Common Signs of Failure

-   Oil seepage around the plug
-   Rounded or damaged tool drive
-   Missing sealing ring
-   Falling engine-oil level

## 🛠️ Service Notes

-   Clean the threads and the seating face before fitting, and make sure the opening itself is clear of old sealant, swarf and corrosion
-   Renew the sealing washer or O-ring where one is fitted rather than reusing a flattened one, and only use thread sealant where the workshop manual for your engine calls for it
-   Tighten to the figure given in the workshop manual for your engine — plugs in aluminium and other soft castings strip easily, and a plug pulled up hard to cure a leak usually distorts the seat and makes it worse
-   Where the plug closes an oil, fuel or coolant passage, run the engine up to temperature afterwards and check the joint under pressure before signing the job off
-   Keep removed plugs paired with the holes they came out of during a strip-down — plugs of very similar appearance often differ in thread, reach or sealing type
