cant figure out which direction to turn the primary drive nut to un loosen it. does it have reverse threads? any help would be much appreciated thanks!
 
That's a biotch to hold on to. You could try sticking a dowel or hammer handle into the exhaust port to lock up the piston. Never tried it but it shouldn't damage anything. Otherwise you have to hold that gear in place somehow.
 
I ended up heating it with a torch a couple of times with an impact wrench to get mine loose. I didn't trust using a penny since they don't make them out of copper, just copper coated.
