Fourth, the assembly is carried out under extremely clean conditions, and the working surface of the parts has no bumps, scratches, burrs and other attachments;
Fifth, strict operating procedures, seals should be installed correctly to prevent deformation in place;

Eighth, if the nut sliding wire is broken or loose, it should be repaired or replaced with a new one, and screwed to the specified torque.
