harmonic balancer shake?

When looking at my belts the other day i started the engine and looked at the harm balancer it realy looked as there was a shake in it. all the nuts and bolts of the pully were tight. may be its on the way out. I would think it would do some real damage running it out of balance like that ? wonder what a new one will run $. ? Any thoughts it is a 7.3 1987 f350 4x4 And on another note I changed that lower radiator hose the funny bent one what a pain in the but working with that thing #@%@#$*

1987 had a 6.9 from the factory.

Is the center bolt in the end of the crank shaft tight?

15/16" socket with a 3" extension, right hand threads.
