Got it apart! Held the output shaft in my vise (copper plates on the jaws so, no damage to the shaft) and then grabbed the input shaft with a pair of vise-grips (small un-machined area, with a rag between that and the vise-grips) and then persuaded on the vise-grips with a hammer! Clutches in there are SHOT! no wonder it was not working properly! I think there is one friction plate with material on one side of it! All the others are worn to bare metal and look like they have gotten pretty hot!
