SlayerLayer Posted August 10, 2016 Share Posted August 10, 2016 So i destroyed my flywheel on Monday and i thought as im going to have to change that i might as well rebuild my engine. But this will be my first 2 stroke engine that i rebuild so i had a few questions, I'll replace all the gaskets, is it worth replacing the 2 bearings and the piston bearing and the 2 seals? Should i also replace the piston ring a link would be good as im not sure which one it is. Its a 26cc losi cy engine Quote Link to comment Share on other sites More sharing options...
mark35 Posted August 10, 2016 Share Posted August 10, 2016 Innovative rc is good for engine spares bud. I use Viton seals as they last longer. You will need to find out if your engine has a 34X0.7mm or 34x1mm piston ring and definitely replace the wrist pin bearing and piston clips. Note....zen wrist pin bearings don't fit cy engines l, and vice versa. Mark Quote Link to comment Share on other sites More sharing options...
losi8igh Posted August 10, 2016 Share Posted August 10, 2016 (edited) Pretty much all basic 2 stroke RC engines work the same way so everything that is in this series of videos can equally apply to the 26cc version as well. You may as well replace the bearings and seals whilst it is open,would almost be silly not to Edited August 10, 2016 by losi8igh Quote Link to comment Share on other sites More sharing options...
SlayerLayer Posted August 10, 2016 Author Share Posted August 10, 2016 I'll get them all and are the piston clips worth replacing? I thought that was only if you lost some when it pings away lol Quote Link to comment Share on other sites More sharing options...
mark35 Posted August 10, 2016 Share Posted August 10, 2016 Put it this way..If one of the clips come out whilst running your engine is toast. They're pennies to replace so not worth the risk imo. Quote Link to comment Share on other sites More sharing options...

losi8igh Posted August 10, 2016 Share Posted August 10, 2016 Might be worth getting more than 2 gudgeon clips as well. One pings out somewhere and you will on the floor trying to find it,just a though for an extra 75p. 1 Quote Link to comment Share on other sites More sharing options...

losi8igh Posted August 10, 2016 Share Posted August 10, 2016 Only "problem" I had with FP was them showing stock that it turned out they never had. Happened quite a few times when I was rebuilding my 5ive. Quote Link to comment Share on other sites More sharing options...
