Can’t understand it; waiting for an expert to provide an answer. Can the original poster post a picture?

1 is a locknut; this screw is installed after the piston and piston rod have been fitted, by drilling and tapping a hole first, so you’ll need to figure out a way to remove it on your own. The torque for 2 is 203 N plus an angle; for cylinders with a diameter of 4.75–8 inches and cast-iron pistons, this angle is 40°. For cylinders with a diameter of 9.5–13 inches and cast-iron pistons, the angle is 35°. For cylinders with a diameter of 15–20.5 inches and cast-aluminum pistons, the angle is 40°, while for cylinders with a diameter of 23–26.5 inches and cast-aluminum pistons, the angle is 45°. After that, drill holes and install lock screws; note that lock screws also need to have anti-loosening measures in place. The torque for 6 is 200N plus 15°
