@AJ
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.
