As spare parts to the hinge antisplash covers, washers, lubricant, a nut of a power shaft and spring lock rings are delivered.

Dismantling of the internal hinge carry out in the following order:

Fig. 9.13. Extraction of spheres from a nave

Fig. 9.16. Nave extraction with a separator from the case of the external hinge

– turn a nave with a separator and take them from the hinge case (see fig. 9.13 ). Take spheres from a separator. To take a nave from a separator, turn a nave in a separator so that paths of spheres settled down parallel to a nave end face (fig. 9.16) ;

– clear all details of the hinge and check their condition. If there are wear tracks or corrosion, replace the hinge assembled.

Assembly of the internal hinge carry out in the following order:

Fig. 9.17. Installation of spheres in a separator of the internal hinge

– insert a nave into a separator, having executed actions in sequence, return to its extraction, then insert into a separator spheres (fig. 9.17) ;

Fig. 9.18. At nave installation in the case the bigger distance on the case (and) should be combined with a nave bottleneck

– establish a nave at an angle 90 ° to the case and check, that the bigger distance on the case was combined with a nave bottleneck then turn a nave and establish it in the hinge case (fig. 9.18, 9.19) ;

Fig. 9.19. The correct turn of a nave, for its installation in the case

Fig. 9.20. A place of pressing a separator for installation of spheres in the hinge case

– be convinced that the flute on an internal surface of a nave is directed to bigger diameter of the case of the hinge. Turn a nave from a separator that spheres entered into flutes in the case, then press a separator so that the nave and spheres were established into place in the hinge case (fig. 9.20) ;

– move manually a hinge nave in different directions to check smoothness of moving and correctness of assembly.
