So i just spent 85 dollars for the tool to remove to pulley bolt but i got a cracking noise after i put the screws in and turned it. Is this bad? Ive never removed the bolt before can someone tell me if I'm gonna break something. I didn't tighten the screws all the way. Should I?

You need to describe the tool you bought.

The home made tool I have has along bolts (high strength steel) which pass through and get anchored in the pulley. Making my tool and the pulley one structure. I just make sure that the threads of the long bolts pass all the way to the other side of the pulley (without damaging the the engine block). I use a 2x4 to lock the home made tool with the driver side wheel and use the breaker bar to put leverage on the bolt. Does require some torque.

Some mechanics put a locktite when they reassemble so a bit of heat on the bolt may be required.

I use the breaker bar starter bump every time so can't really help you out there.

It depends on how far in you threaded the bolt, but it sounds like you put the bolt in too far and it cracked the plastic timing belt cover.

try and heat the bolt to help loosen it up.

Of course i try loosening up the bolt and it broke off inside the hole of the crank shaft pulley i dont know what to do now. Ive been trying to get this bolt off for over a month and now i have to leave for football camp in 2 days so I will not have my car on campus this is just horrible I'm getting the worst luck and I'm not even half way through the head gasket change. HELP ME GOD

thats a tough break right there. that bolt is seriously hardened so drilling it and getting an extractor on it will be difficult, not to mention it didn't budge the first time. if you haven't been soaking it in penetrating oil now is the time to start. do not heat the bolt and try to remove it the bolt will expand and make it more difficult, only heating the area around the bolt would help. you can heat up the bolt let it cool down and try it in an attempt to loosen up the bond but don't turn the bolt when hot let it cool down again.

ideally at this point the crankshaft needs to come out to make it easier to deal with or even replace the crankshaft, but that a ton of work so try and extract it first.

you can even get someone who had a mobile welding setup to come and weld something to the end of the part broken in the trans and hope there is enough of a bond to break it loose, after soaking it for days in penetrating oil. sometmies a good whack with a hammer on the end of the bolt could help loosen things up but try not to mangle the part thats left.

Wow that's a first time I've heard this happening. .that bolt is hardened to prevent this from happening

The way i'm reading his post is that the bolts from his tool broke inside the crank pulley, not the actual crank pulley bolt.

OP, any word on what ended up happening? having a hell of a time getting this bolt off.

I'd recommend buying the Schley Products 64300 harmonic balancer holder.

I tried taking a crank pulley bolt off once using the starter method, and it wouldn't budge. I bought the SP tool and used my 25" long Snap On ratchet on the bolt with a breaker bar to hold the tool + 2 people and it came off with a little effort. Another benefit of having this tool is that you can torque the bolt to spec when you're done.
