Transmission installed wrong?

Hi all,

This is probably a stupid question. I just installed a reman engine in my 2000 4.0 manual. I went to tighten the vibration damper bolt, and so put the transmission in gear to hold it. However, when I go to tighten it I can still turn it. I thought the transmission would hold the crankshaft and make the vibration damper unable to be turned. Could I have installed something wrong? Should I pull the transmission? I can see the flywheel turning through the hole for the starter, but have no idea if the clutch is engaged or not. I don’t want to pull the transmission if I don’t have to, but I don’t want to start it up if something is installed wrong. Thanks!!

Is the transfer case in neutral ?
 
Huh. Well that’s wierd. That worked. Allowed me to tighten it to 80ftlbs without turning. Why is that??? I’m really confused. Im not much of a car guy - mostly just able to follow FSM.

It would make the highest resistance to the torque input .

I hope you didn't draw the crank pulley on with its own bolt.

You can easily strip the threads in the crank.

I did exactly what I think you did the first time...and the pulley wasn't fully seated...it ended up cutting a belt as it was one rib off.

$20 in hardware can set it correctly...6" threaded 1/2-20 rod, couple bolts and washers and a bearing.

I put it on with the pulley tool. I rented the puller and installer from autozone. I just couldn’t get it from turning to torque it to 80ftlbs. It kept turning, despite me putting it into first and reverse. Putting it into 5th gave me the resistance to torque it down. I’m relatively confident it’s seated correctly, but I guess we will find out when I crank it up.
