Harmonic Balancer Removal ?
 

Do i need a puller to remove the balancer? Or, does it just bolt on with a key?

you need a special puller.

GREAT!! That sounds expensive.

you can probably rent one from autozone.

canadian tire lets you borrow them, you pay for it and they give you the money back when you bring it back... just ask auto

its called a harmonic balancer puller
