It shouldnt since the timing belt is not being removed or anything, just the serpentine/Vbelt...

 

since the belt is still on, when the crank moves so does everything else. it just gets moved out of TDC very very very little. i just took off my head and the cylinders were still at TDC.

 

okay, had my dad hold the brakes and gave it everything ive got and no budge... r u sure this wont damage the crank by having somebody hold the brakes while you wrench at that center bolt???

 

You're gonna have a helluva time loosening that bolt by hand, but it can be done. Try sliding a small length of pipe over your breaker bar to get a little more leverage. You may need to get that side of the car way up in the air to give you a little more room under there. Some auto stores around me will loan tools for a returnable deposit. Try an Auto Zone, etc.they may have a cordless impact wrench you can borrow. If you do use an impact be mindful when putting the pulley back on to let the impact just turn the crank bolt, keeping the impact socket just slightly back from the lip of the bolt. An impact can damage threads if you let it pound the bolt back in.
You're not going to damage anything by using the brake etc. Once you get the bolt lossened though, do you have a 3 jaw pulley puler? You won't be getting that pulley off without one.

best of luck with your project!

 

yes with the 3 jaw it took me 3 min to get the pully off there I love it!!! anyways GET AN INPACT i have a dewalt electric one and it works fine for everything i did while i was at home it was only like 90 bucks and then i paied like 12 bucks for a cheap set of inpact sockets best money spent

 

i have a 600ft/lb snap on impact wrench that works awsome too.....takes about 15 seconds with the right puller to get that pulley off
next though i plan on getting a new nitro cat impact......1000ft/lb is just awsome

 

I dont know why people say it is so hard to get the bolt off by hand, I just used a 1/2 ratchet and it came right off, oh, and a screwdriver in the block

 

the screwdriver in the block is the same way i used to do it all the time......atleast until i ran out of screwdrivers

 

lol spud I dont need that much torq my dewalt only has 345ft lbs but thats all i need. plus for 90 bucks ya cant beat that

 

yeah i know....i just want alot of power......1000ft/lbs would be really nice to have....and its only $180
i wanna know i can break lug nuts off if i want to
