904 disassembly help needed

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!

Good deal! Sounds like the clutches were really welded together. Must have got real hot.
