amayanak Posted November 21, 2015 Share Posted November 21, 2015 Hi there... I really need your help guys.. I bought piston ring sit for my Yamaha DT175.. The other ring has an " N " mark in it.. So where would I put this Top or Bottom groove of the piston? Link to comment Share on other sites More sharing options...
Moderator Airhead Posted November 21, 2015 Moderator Share Posted November 21, 2015 Not sure about the N mark but usually the bottom groove is parallel and the top one is a keystone section so look at your piston rings and fit them appropriately Link to comment Share on other sites More sharing options...

Moderator Airhead Posted November 21, 2015 Moderator Share Posted November 21, 2015 (edited) Si airhead... what do you mean when u say "keystone" ??the keystone ring will be thinner at the inside diameter and thicker at the outside diameter and so the top ring groove will taper to accommodate that If you put the bottom ring in the top groove it will not seat fully, it will stick out a little from the side of the piston see here, and note from the link that 'N' faces up when fittedhttp://www.golfcarnews.com/technically-speaking-mayjune-2008/ Edited November 21, 2015 by Airhead Link to comment Share on other sites More sharing options...
