Cracks, idk.....

But you can use a prybar or big screwdriver on the teeth. They also make a flywheel turner... it's like a huge pliers.

Or you can disengage the fuel pump and bump it with the starter.

 

I use the socket and breaker bar on the front pulley, removing the spark plugs makes turning it easier.

 

+1..… 15/16" socket and the engine will rotate no worries.

 

Yep, crank pulley...but I don't see any cracks in the flywheel.

 

Don't see any cracks, either.

Looks like a little dust/rust residue from where the bolts are on crank/flex-plate...but see no cracks.

Auto trans flywheels tend not crack, ususlly only manuals from clutch wear and abuse.
If your torque plate/flex plate was damaged like the one pictured, you would definately hear it, especially when on/off the throttle or when it shifts.
Leave the transmission in park when breaking the crank pulley loose.
