I'm removing the rear brake drum on the M20 but have hit a snag. The hole in the center of the drum can't move past the flange on the half spindle (66-6104). Does the half spindle need to be driven out of the brake plate? Or could the bike have an incorrect spindle?
I'm not sure what problem you're encountering? But once the main wheel spindle is removed, the only thing holding the hollow half spindle in is the drum itself. It should come off with the drum. Even so, it should still be able to pass through the hole in the drum, otherwise how was it put there in the first place? Ron
