1. Clean cylinder contact surface.
2. Insert the two compression rings one after the other into the unworn area of the cylinder wall and measure end clearance with feeler gauge; replace
piston rings, if necessary.
The gap clearance of the oil scraper ring cannot be checked because of its three-part design. If the compression rings are replaced, the oil scraper ring
must also be replaced.
