88 M5OD Flywheel Installation.
Had to replace the clutch in my f-150, with M5OD tranny and 302. Also had to replace the flywheel. Started up the truck and now the engine shakes like crazy at anything above 1000 rpm. I think the Flywheel is installed wrong. I put it back on the same exact way I took the old one off, but it seems the offset weight is causing the shake. The flywheel I got is the right one (E8TZ-6573D).
Does anyone know how I can verify that the flywheel is installed correctly? I know I gotta pull the tranny again, but I need to know how to line the flywheel up correctly. The flywheel has the weight on the back and the front of the flywheel has a dot drilled in it to tell me where the weight is. Is there something on the crank that tells me which way the weight goes? I noticed on the crank there are 6 bolt holes and another hole between two bolt holes. Do I use this for determining where the weight goes?
I really need some help now, or I have to take it to shop.
Thanks
Randy

Various 302's over the years were either internally or externally balanced. It sounds like you got the wrong flywheel for your application (I don't care what the book says, or the kid behind the counter). If you've still got the original flywheel take it to a machine shop and have it re-surfaced. Basically, they put it on a lathe and mill off a small amount of the surface to bring it back "true". Very similar to having rotors turned. Then put it back on the truck. This should solve your problem.
