No puller needed. Watch your toes.

A different question to ask, though, is how you lock up the front pulley (harmonic balancer) while you loosen the bolt and, later, when you tighten and torque the bolt.

An air impact wrench is not such a good idea on the B230 series (even though it was a fine idea for the B21/23 engines). The crankshaft in the B230 is cast (vs. forged in the B21/23). A cast crank is very brittle, and you have a slight chance of shattering it with an impact wrench -- admittedly low probability, but not zero probability, and not an easy or cheap repair if it happens.

Get the crank tool, if possible. It makes it all sooooo easy. (Construction plans are in the archives.)

You can probably find a way to jam a screwdriver in the ring gear.

Look in the archives for "rope trick" (no, it's not holding the front pulley with a rope). Don't consider a strap wrench -- you'll tear apart the rubber donut in your front pulley (harmonic balancer). Anyway, the required torque's too high.
