Cracked the crank pulley

Cracked the crank pulley
Ok I unscrewed the crank pulley bolt minus a 5-6 threads to keep it stable
Put on the pulley puller, started cranking, thought it was working then the pulley cracked.
what did I do wrong?

jm, idk why people use pulley pullers, if you just pull STRAIGHT off, and maybe losen it up my hitting it with a rubber mallet, it slides off really easy. I never use tools like that because of things like this, your hands are the pretty reliable...and i say YOUR because mine definately aren't. Every time I've removed my pulley ( twice) it has come off with the losen-with-hammer and pull straight off method. Put a picture up of the crack!!

But I have another problem...
I bought a 79 pulley thinking it would be the same as the 81...
Nope. 79 has 13 counter balance holes, the 81 has 6
Is this going to shake my crank to pieces?
This is that learning curve that saves you alot of money when you're older I guess..
EDIT: also anyone know what kind of metal these are made of? Im thinking about getting the ag mech class at school to weld my old pulley back together and clean it up. Im not spending another $40 on this POS.

Damn man, that sucks. When I did it I pulled the pulley bolt all the way out and then used the pulley remover (Didn't realize u could do it with a rubber mallet lol) and mine came out just fine. Minus the timing cover of course lmao

I was thinking what you were but we both may be wrong.
EDIT: I was informed that those were in fact balancing holes (like the opposite of wheel weights) and every pulley is different so it has different balancing holes. Awesome!

Hey 2 by 2, trust me the lessons never end: Heres a few that I learned from my rebuild which I'm sure you will want to know, since it can't hurt:
NEVER hot tank aluminum parts, I hot tanked my pistons and front cover simultaneously bye 280 dollars. Green pistons and a green front cover. It oxidized and well just dont do it.
2. DON'T take your cam towers off, they are factory aligned. Just push the rocker arms down with a big screwdriver and take the cam out if you have to do any head-work.
3. NEVER trust any P.O's words i.e. "this head is brand spankin new!"
4. Never buy from pierre'z
5. NEVER BUY FROM PIERRE'Z
6. Prime your oil pump ANY time you take it out, DONT forget.
7. ANYTHING with springs in the assembly should be re-read and approached with über caution because those things can shoot things in places you don't want. Valves, tensioners, distributors, AFMs, anything with a spring!!
Whatever you do, work slowly and just think I'm pretty sure that can be the solution to every problem I've ever had, its just I never did a mental play-by-play the little things i.e. removing a simple cam tower can end up costing you days in the long run and hundreds of dollars. If you have ANY doubt, ask someone if you have NO doubt then still ask someone.
just my $.04 It really does suck learning but if it helps someone out there then i guess its worth it!!
