Help...Flywheel/Crank Locked-up

I started an earlier thread about changing my clutch. Well, after removing/re-installing my flywheel...to change my pilot bearing and RMS...the flywheel and crank are locked-up...I can't turn the crank from the front crank pulley...I'm thinking the flywheel bolts are too long, but their the same ones I took out...do any or all of the bolts take a washer or??

Silly question..

Is the clutch installed? If so - tranny in neutral?

I assume the starter is still out?

From what I recall, the bolts are all the same size on the flywheel. They'd have to be pretty long to cause a problem I'd think

Yes, the clutch and starter are still out...I removed the flywheel to change the pilot bearing and rear main seal (RMS)...I needed to turn the crank for clearance when torquing the flywheel bolts down and it wouldn't turn...it turned before I re-installed the flywheel?? Are there supposed to be washers on the flywheel bolts??

Loosen the flywheel back up and see what happens.

Yes, the bolts are all the same length. However, I'm 99% sure once I loosen the bolts, it will free up the crank. But, why...what went wrong :?

I know that the bolts on my flywheel (on the 4.9 new build) do not have washers. Come to think of it, I haven't tried turning the crank since I installed the flywheel.. Think I'll try that this afternoon...

The crank didn't get locked-up, until I tightened down my flywheel. This job is really kicking my *** :/

If you loosen the flywheel, can you turn the crank?

In looking at mine, the bolts would need to be WAY long to lock things up. Did you do anything else? Install the rear main seal?

I'd loosen it up and be 100% sure that is the problem before I started chasing things.

I know you said you are 99% certain loosening it up will allow it to turn. I'm betting it either won't, or in the process of loosening it up you'll figure out the problem.

I changed both the pilot bearing and rear main seal (RMS). It took me forever, just to get the flywheel lined-up and bolted down...I was able to spin the flywheel before I tightened the bolts down...I can't imagine the RMS is locking it up :?

You could spin the flywheel, but was the crank turning or just the flywheel?
I think there is something else wrong.
I know it's a pain, but loosen / remove the flywheel and try the crank

Yes, I could turn the crank/flywheel from the balancer. I know I will have to pull the fly back off...I'm just trying to troubleshoot a bit...before I do it.

I think the RMS is sticking out too far.
Did you pre-lube the seal?
They don't like starting dry.

Yep, I pre-lubed. The seal is flush with the edge of the rear surface of the block/cap. I just can't imagine that would stop the crank from turning.

On the 4.9 is there a spacer/dust plate that goes onto the back of the block before the flywheel is installed?

If you loosen the flywheel a bit, at what point is the crank able to rotate?
You can't hear anything rubbing or dragging when you turn the crank?

Right now the crank is 100% locked-up. Yes, there is a plate that goes between the fly and block...starter bolts to it.
