Hi John,
I need some advice on an 1850 PTO. It snaps in too hard, so I am going to try to adjust the clutches as explained in my IT book. I can't get the plug loose on the back of the PTO housing. I made a hex stub out of a 5/8 bolt and nuts. I can't get it broke loose. I'm afraid I will round out the center of the hex. Do you have any suggestions? I really hate to heat the housing. I thought about maybe drilling several 1/8 holes all in a line from the edge to the center of the plug in hopes of letting the plug contract. 

What do you think?

Thanks,
