If memory serves me, that is a reverse thread on the input shaft. However
I could not
find that in the manual that I have right here. Stay tuned and some one
If you lock an old clutch disc in a vise and insert the input shaft in the
hole this should
give you a good leverage opportunity to loosen the nut.
Just clean up the input shaft nose and you should be good to go.
