## 🔌 Function

Locks a threaded joint in the mechanical speed, fuel-control or stop-linkage assembly, holding the adjustment where it was set.

## ⚠️ Common Signs of Failure

-   Linkage adjustment drifting so idle or maximum speed changes
-   Nut found finger-loose on inspection
-   Thread found galled or the nut found seized by corrosion
-   Rattle from the linkage as the joint slackens

## 🛠️ Service Notes

-   Reset and recheck the linkage adjustment after fitting - a locknut that has been slack means the setting has already moved
