[Healeys] BN2 tranmission question

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 
will confirm
this shortly.

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.
