How do you take off harmonic balance without puller on 1992 Buick regal custom?

To remove a harmonic balancer from a 1992 Buick Regal Custom without a puller, you can try tapping it gently with a rubber mallet while applying a bit of penetrating oil around the crankshaft. Alternatively, you can use a piece of wood or a metal block to protect the balancer and use a hammer to lightly tap it, gradually working it loose. Ensure that the crankshaft bolt is removed first, and be cautious to avoid damaging the balancer or crankshaft. If it’s stuck, using heat from a heat gun can also help expand the metal and facilitate removal.
