SOLVED Removed the back cover plate on the arm loosened the right hex head screw just ever do little. There are 3 hex head screws back there.

I have a Craftsman Radial Arm Saw Mode, 113.19771. The indent (Index) pin releases the arm and the arm swings smoothly to the right, indexing at 45 degrees. When I release the pin and try to move the arm to the left, the index pin starts to ride on the track but then abruptly stops with a clank, metal on metal sound. I have tried loosening and tightening the bolts and hex screws on the back of the column but it didn't help. I've taken the top cover off the arm and have disassembled all that could be removed. No idea what the obstruction could be.
