🔌 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
