Piston ring end gap measurement
1
Clean the cylinder barrel.
2
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.
