- Clean the cylinder barrel.
- Insert both compression rings one after the other above running surface in the cylinder bore, and measure end gap with a feeler gauge; replace piston rings if necessary.
The end gap of the oil scraper ring cannot be measured because of its three-part structure. The oil scraper ring must be replaced along with the compression rings.
