And why are you taking the crank out? Anyway...
You can't remove the crank without removing the engine. The first people are going to say is "yes you can!". No, you can't. You would need to remove the trans and then drop the engine to get access to the oil pump, and by that time, the engine is pretty much out anyway.
The crankcase on the Ecotecs split at the centerline of the crankshaft. Once you have it on a stand, it's really very easy.

well once you get the motor completely out of the car you wanna remove the oil pan and the oil pimp and pick up...should be one bolt holding it in...then you want to unbolt the rods. if you are reusing the rods mark which cylinder they came from and the direction they were facing. you want to make sure they go back EXACTLY the way the came off and go back into the EXACT same cylinder. same with the bearings. push all the pistons to the top of the motoe and then mark the mains the same way you marked the rods. you want everything to go back in the EXACT same place, direction, angle. etc you removed it from. so mark everything.once you remove the mains you should be able to pull the crank out. it's probably going to be heavy and it might stick on the ends where the seals are and be careful you don't drop it. once the crank is out you can push the pistons out the top of the motor. you might have to tap them on the bottom with the butt end of a hammer. be careful not to ding the rods if you are reusing them if you have to tap the pistons out. and you should be ready to go to the machine shop.

yank it all man it will make your life easier. just disassemble it after you get it out. if not you are going to be trying to line everything up in confined spaces.

If you have it that far disassembled, to where you only have the lower and upper crankcase together with the oil pump still on the side....
1. That only weighs a little over a hundred pounds by now. Just get a buddy to help you lift it up, it's not that bad.
2. Just finish taking the thing apart. The machine shop is going to take it apart anyway to do the cylinder work. They won't hone it with all that other stuff still attached. And you don't want them to. Get the crank and it's bearings out of there so they don't get any metal on them.
3. You will want to get new crank bearings (cheap, just do it) and you have to get new crankcase bolts. They are one-time use. You may consider getting studs since you have it apart. They are reusable if you ever take the engine apart again.
