Moderator Airhead Posted October 9, 2013 Moderator Share Posted October 9, 2013 a few points here The rings are different, the top one has a 'keystone' profile section (it's thinner on the inside circumference than the outside circumference...this on goes into the top groove The other ring is flat in Its profile section, this one goes into the bottom groove but first put in the little springy thing so that the ends are either side of the locating peg You'll notice that the rings have a shape ground into the ends so that they fit correctly around the locating pegs Link to comment Share on other sites More sharing options...
YPVS TONE Posted October 9, 2013 Share Posted October 9, 2013 The expander ring fits under the bottom piston ring. Link to comment Share on other sites More sharing options...
