monstaru Posted January 13, 2006 Share Posted January 13, 2006 anyone know the difference between ea-82 and ea-81 flywheels?i obviously don't so when i was looking at the few i have in my garage they all looked the same,but out of the three the ea-82 clutch pressure plate fit all of them.i know i do not have three ea-82 flywheels so,i need to figure out the difference.thanks, brian Link to comment Share on other sites More sharing options...
edrach Posted January 13, 2006 Share Posted January 13, 2006 Brian, that's a tough one. I've had a similar problem in the past since I use the EA82 flywheel in my Brat to mate up with the 5 speed conversion. Check out the 8 holes that mount the flywheel to the crank. The EA82 uses a slightly larger bolt than the EA81. There's not much difference, but it's there. Also, I believe the timing marks on the outer perimeter are about 20 degrees different. anyone know the difference between ea-82 and ea-81 flywheels?i obviously don't so when i was looking at the few i have in my garage they all looked the same,but out of the three the ea-82 clutch pressure plate fit all of them.i know i do not have three ea-82 flywheels so,i need to figure out the difference.thanks, brian Link to comment Share on other sites More sharing options...
monstaru Posted January 13, 2006 Author Share Posted January 13, 2006 well, do i absolutely need the ea-82 flywheel for thta 5 spd conversion then...? it seems the clutch pack would fit fine.....has anyone tried it to see if it would work?what is the reasoning behind utilizing it..thanks, brian Link to comment Share on other sites More sharing options...
bratsrus1 Posted January 13, 2006 Share Posted January 13, 2006 Hey Brian This is Jerry, no you don't need a different flywheel. You have the 8 and 7/8 flywheel and thats the flywheel you use on this change over. Everything is cool i have it handled, i have the other clutch disc that you need for the 5 speed already for you. Thanks Jerry Link to comment Share on other sites More sharing options...
MilesFox Posted January 13, 2006 Share Posted January 13, 2006 another difference is ea81 flywheels are beveled on the inside edge wheras ea82 are cornered use the flywheel for the tranny you are using flywheels will fit eaither way, ea82's onto ea81's and ea81's onto ea82's if you drill out the holes Link to comment Share on other sites More sharing options...
NoahDL88 Posted January 13, 2006 Share Posted January 13, 2006 I hate to disagree with the Fox, but i'd reccomend using the flywheel with the engine you are running. As far as which is which, the outside of a EA-82 is a square edge, where the EA-81 very clearly had the corner machined off. Link to comment Share on other sites More sharing options...

Works fine with the EA81 engine. Only hassle I had was the extra space I had around the smaller bolts. 'Solved that by cutting short lengths of brass tubing to slip over the bolts to take up the potential play. Link to comment Share on other sites More sharing options...
