What a waste

He actually asked for it. It has a storied history in the T/OT section. Part of it can be viewed here for those who care.

back on topic.

of course if the flywheel was off center a bit it wouldn't put any undue stress on the input shaft.
the center line of the crank would still be the same as the clutch friction disk.
the flywheel and pressure plate would just be off a bit, like the lobe of a cam shaft.

but i'm wondering if without the bronze bushing to center the flywheel while installing.
if the flywheel was eccentric to the crankshaft.
and the centrifugal force was enough to shear the bolts holding it to the crankshaft???

i didn't see it happen, but i saw the aftermath of a flywheel coming UP through a bell housing and ripping through the floorboard of a ford pickup.

Some excellent and factual information was presented on this post as to why a pilot bushing will be no help on a Fiero manual. The evidence was concise and clear.
In addition to the many pages of posts I also received several PM"s on the topic; simply reiterated what was already said but the PM"s and the argument continued.
I don't know the man who started this post and he may be a nice guy, but lets not flame him. He is so obviously suffering from some deep seated and profound psychological problems.

Now that we got all that behind us... This picture is very interesting and IMO tells a lot about what happened.

Looks like the flywheel broke off, probably due to shear forces from the imbalance caused by the flywheel being off center due to a missing centering bushing or insert. Rule of thumb: If you're having to line the flywheel up by eye, something real bad is fixing to happen.

It would be pretty hard for an off-center flywheel to pass QC. I suspect that he used an unbalance flywheel or that he over torqued the bolts causing them to fail from stress factures under load. That would be just as destructive.

You're right, that was a waste of 21k posts.

Score one for the Forum. I have yet to see a productive post by him. Im sure he'll feel right at home on the troll forum with the rest of them.

Anyway, reason Im posting, update. I heard back from the Fiero store, the 'pilot bushing' they sell, is in fact the proper size to allign the crankshaft, 1 7/16ths I think he said. I didnt bother mentioning anything about the semantics of it, just asked what the dimensions were.

So, if you need one, you can get them from the Fiero store.
