I'm in the process of changing the transmission oil seal on the right side of my BN and hit a problem with a bolt. Previous owner had put on a 3 pit hitch and welded a spacer to the cross bar that the swinging drawbar attach to and bolted it to the bottom of the axle tube. He used the spacer as the swivel point for the 3 point hitch arms. Problem is I need to disconnect it from the axle tube and one of the bolts is too close to the part used for the 3pt hitch swivel to get anything other than an open end wrench onto.I can't budge it with that type of wrench. The other bolt I could get a socket onto and it took a piece of pipe on a breaker bar to move it so the bolts are tight. Is there anything other than a torch that might work on this thing. I can't think of anything but thought I would ask first before I do something I'm sure to regret. It was pretty clever the way the hitch and hydraulics were added to the tractor but it makes working on the tractor a real pain as all the add on parts are in the way of doing anything. If I had a drawbar I would cut the spacers off but I haven't seen a drawbar for a BN for sale yet.
