## 🔌 Function

Seals the combustion gases above the piston, controls the oil film on the bore and carries heat into the cylinder wall.

## ⚠️ Common Signs of Failure

-   Bore glazed, scored or with a wear ridge at the top

## 🛠️ Service Notes

-   Standard size only — measure the bore first, because a rebored cylinder needs the matching oversize kit
-   Check the ring end gaps in the bore and the groove clearance before assembly
-   Hone or deglaze the bore as the workshop manual directs so the new rings bed in
