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

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.

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

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

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

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.

I used the EA82 flywheel since it's more massive; a little slower getting up to speed, but more momemtum when you're there. 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.
