The threads are fine on both the fixed and sliding sheaves. What happen was i stuck a bar through the clutch to hold it in place. When i started to tighten the puller the fixed sheave i guess turned and the sliding sheave did not. Since that happened the sliding sheave unscrewed from the fixed sheave. So yes i believe that the spider unscrewed from the fixed sheave shaft.
Doesn't the puller thread into the shaft,which is part of the inner sheave,like I said been awhile. So I guess the problem you have now is holding the inner sheave from turning? If it is trashed anyway I would probably try carefull drilling the inner sheave so you rig up a bolt or something and use a bar between the bolt and the clutch shaft...just be careful you don' drill through the sheave into the engine lol.
You DONT need an impact IMO...tighten the puller good and tight and tap the end with a hammer,not too hard just some light taps,then it should loosen a little,tighten and repeat until it comes off.
