## 📋 Kit Contents

-   1 x complete piston ring set for one piston - Volvo Penta 21010337
-   1 x top compression ring - supplied only within kit 21010337
-   1 x second compression ring - supplied only within kit 21010337

## 🔌 Function

The rings seal combustion pressure above the piston, regulate the lubricating-oil film on the cylinder wall and conduct piston heat into the liner.

## ⚠️ Common Signs of Failure

-   Low compression or excessive crankcase blow-by
-   High engine-oil consumption
-   Blue exhaust smoke
-   Poor starting or reduced power
-   Ring lands, piston or liner are being renewed during overhaul

## 🛠️ Service Notes

-   Check the end gap of each ring in the bore it will run in and compare it with the figure in the workshop manual for your engine; a worn or rebored cylinder changes it
-   Fit the rings the right way up — where a face is marked or the section is stepped, that face goes towards the piston crown, and an oil control ring's expander must be fitted without overlapping its own ends
-   Use a ring expander rather than levering rings on with a screwdriver, and open them only as far as they need to go; cast rings snap and the groove edges nick easily
-   Stagger the ring gaps round the piston as the manual for your engine directs, so that no two gaps line up
-   Oil the rings, bore and compressor lightly, enter the bore with a ring compressor, and never force the piston in — if it resists, back it out and find out why
