## 🔌 Function

Rides on the cam lobe and passes its lift up to the push rod, converting the cam's rotation into straight-line movement.

## ⚠️ Common Signs of Failure

-   Tapping or clatter from the valve gear that does not clear when hot
-   Face worn hollow, pitted or scuffed
-   Tappet tight or sticking in its bore
-   Matching wear found on the cam lobe
-   Valve clearances that keep opening up

## 🛠️ Service Notes

-   Inspect the cam lobe whenever a tappet is worn, as the two wear together and a new tappet on a worn lobe will not last
-   Renew the tappets as a set if more than one is marked, and reset the valve clearances afterwards
