ummm... your talking about taking a hammer to a balancer pulley.... Balance.. as is weight distributed evenly..... if u do make sure its a rubber/plastic tip mallet... Ive taken em off many times.. using a pulley puller is alot easier.
u cant mess up TDC... u can only mess up the balance of the Crank and the location of which the arrow points which can affect rocker adjustments if u choose to use the arrow as a way to determine TDC... Just do what i say so u do it right

 

so it comes off, dont beat on it. put it back exactly where it was before, and all is good?

 

^^^ ???

 

Go to autozone, rent a balancer puller. If u use a hammer you'll get tired, annoyed, and pissy. LIke i said.. just make note of the arrow position when u take it off. and for some reason if u dont have an arrow just use a pencil to mark the way it came off.

 

it only lines up one way. the bolt holes arent even.

 

anyone have a balancer pulley puller thingy that i can borrow? im in carrollwood.
