Agitator in washer wobbles

Loosened the set screw and removed the agitator, found nothing wrong. Replaced the agitator and tightened set screw, no more wobble.
This is a mid 1970 Maytag and a workhorse.Had three kids wash over the years, now "kids" in their late 30's and early 40' and washer is as good as new (except a little rusty)

First time I had a problem with it. Sometimes just look for the simple things !

Part select refunded me for my part that I ordered very fast.

Great Company to deal with!
