Sometimes you can get the ring spread a little bit with the usual lock ring pliers....just enough spread and twist will make one side of the ring open up a gap. You can push a thin blade screwdriver into the gap and carefully twist the screwdriver. This may get the one side out of its groove. Place the shaft into a vice, clamped between two thin pieces of plywood. Snug it good and tight. Now you can fit any old beater screwdriver into the groove and tap it with a hammer to force the ring out of the groove as you tap the screwdriver all the way around. Usually the lock ring wants to stay in the groove until the very last 1/4” and then it pops out entirely. For some reason those lock rings by the speedometer gear are almost always tight like that.
