Help! I'm attempting to rotate the gearbox on a 503 180 degrees and have encountered a frustrating problem. There are 2 bolts that mount the gearbox enclosure to the engine, and they were torqued very tightly. The bolt on the right will not break free. I even used an impact wrench until it started to round over the bolt head, so I stopped until consulting the forum.
What I noticed is that there's a little cut-out in the bearing boss for bolt clearance, which was sufficient on the left bolt to accommodate the slightly thicker socket for impact wrenches. The right cut-out is not, so I can't fully seat the socket over the bolt head. Regular sockets clear the head, but I can't get enough arm leverage to break the bond. Any ideas from the group? Thanks in advance.
