Using the matching torque wrench, the distance between the 2-3 nuts is removed, and the disassembly is carried out in diagonal order. The disassembly of the diagonal can effectively reduce the irregular force of the bolt and reduce the fatigue loss of the parts. If you use a motor wrench, you need to adjust the air pressure, the specific pressure depends on the size of the nut.
