the kenmore model is 110.26912691
direct drive top loader washer.
the part looks like that one. except its now missing the top flat part with the slots. (due to having worn/broke) the shaft tabs still look good though. since i did not have the means to get a spanner wrench i used the hammer/flat metal angled into a slot of spanner nut until it started moving. after it got about 1 turn , the drive block part started turning along with it. i was then able to slide the inner tub out with drive block/spanner nut still attached.
@bigbuck, i might try that. or a similiar method.
i figure if i can manage to get the drive block not to turn along with the spanner nut i could remove it. but at this point even a spanner wrench wouldnt stop the drive bolt from turning along with the nut.
