## ⚠️ Common Signs of Failure

-   Excessive throttle free play
-   Linkage sticking or binding
-   Uneven idle speed
-   Pin wear or corrosion
-   Linkage separation

## 🛠️ Service Notes

-   Check the pin and its bore for wear, ovality, scoring and corrosion; a worn pin in a worn bore shows up as lost motion in whatever it links
-   Fit the pin the correct way round and to the correct depth, driving it with a punch that bears on the pin rather than on the surrounding casting
-   Secure it with the same retaining device as originally used — a new split pin, clip or circlip; never reuse a split pin and never straighten and refit a bent pin
-   A light smear of a suitable marine grease on assembly slows corrosion and keeps the pin free for next time
-   Check that the linkage or component the pin carries moves through its full travel freely once everything is assembled
