## ⚙️ Key Features

-   Castle nut
-   0.024 kg
-   Supersedes 20367040, catalogued earlier as a nut retainer
-   Listed for 120 applications across D, TAD and TWD series engines
-   Retained by a pin through its slots

## 🔌 Function

Clamps a joint and is then locked by a pin passed through its slots and the drilling in the stud, so it cannot vibrate loose.

## ⚠️ Common Signs of Failure

-   Play appearing in the joint the nut secures
-   The locking pin found sheared, bent or missing
-   Slots in the nut spread, burred or damaged by a worn pin
-   Thread stretched, picked up or seized on removal
-   Nut face bruised or corroded so the clamp load cannot be set

## 🛠️ Service Notes

-   The locking pin is single-use - fit a new one whenever the nut is disturbed and never reuse the old one
-   Tighten to the specified figure and then advance to the next slot rather than backing off, so clamp load is not lost
