I can't find it right now, but I'm curious; why do you want to know? I have a shop manual in the garage, so I'll try to remember to find it while I'm out there this morning.

What do you mean by "Go out"? If your engine spun a bearing, usually you cant just replace the bearings. It usually causes some damage to the crank, rod or both. This requires some machine work to fix. Unfortunatly, you cant just turn the crank down due to it being surface hardedned. Turning it would remove this and can cause the crank to fail. Since you are saying that it did effect the crank in some way, I would be leary of just replacing the bearings.

The 3.0 crank and the 3.2 crank are the same. When swapping parts in the rotating assembly you should have things balanced though. Also, did you check the bearing clearances with the new bearings? Were they in specs?

Hey man, if I read you right, you just don't replace the bad one. I'd replace all of them. I just want to make that clear.

It is possible to have bearing be as thin as paper and not spin. I assume you checked on it though because you heard a jackhammer coming from your engine bay. If so, your crank is likely toast.

Never been a noob...
Before you toss a new bearing in that rod, I strongly suggest you check to see if the big end is out of round.

No, don't turn the spare crank or the damaged one for that matter, or what Jayro said could or would happen. Throw that damaged crank in the trash.
Bad one what? Rods? Or bearings? Rods no, just the one that had the paper thin bearing in it. All rod bearings, yes, and the crank
This.

It's not just using a crank from a different size motor, it's using a crank from a different motor period.
When these were assembled at Ford, they balanced the rotating assembly first. If you change anything in the rotating assembly (that's crank, rods, pistons), even if it was from another 3.2L, you need to balance it again. In your case, you're changing the crank and a rod, so there's a decent chance that it will be a little off-balance when it's all buttoned up. Balancing it makes sure that it's smooth and doesn't shake itself to pieces (may be a little exaggerated, but you get the point).
