Upper and lower bushings are critical to keeping your hydraulic hammer running right. These bushings keep your point or chisel in place during work. Each bushing needs to be made to OEM standards to keep the correct profile and contours and correctly seat your working tool. When your lower or upper bushing is worn, your tool is not “Square” with the piston. This will lead to a cracked piston, cylinder damage and seal damage.
