It's not important. Just one of those 1J/2J converts volunteering their opinion on the 7M series engines.

Anyway, the pulley on the crankshaft is the harmonic balancer. If it's wobbling that badly it could be a few different things. The balancer itself could be shot or out of balance (yeah, I know, ironic), the key/keyway on the crankshaft could be messed up. In any event I'd say that you're going to end up having to pull that pulley off and checking to see why it's got so much wobble.

Here's a link with a diagram of what's what along with the part numbers.
