how to take crank pulley off
 

ok, the crank pulley that the timing belt goes around, theres a bolt in the middle, its on there REALLY tight, how do i get that off of there!? its not the pulley for the serpentine belts, but the one with the teeth for the timing belt

I believe its a 1/2" drive or something like that...

yea i know, air tools arent strong enough (at least the ones i got) and ive put ALOT of force on it, is there a trick?

ok i got the bolt off, now to take the pulley off, is it pressed on there? its on there REALLY good

so how do i get the pulley with the teeth off? do i need a puller tool?

yep you can rent it at auto zone or discount
