| 1. For removal of the external hinge it is necessary to release a cover 4 (see rice. The drive of a forward wheel) from two collars 2 and 5, accurately to pull together a cover from the case and to advance it on a shaft for the purpose of receiving access to a locking ring 3. |
| 2. To clear the face surface of the hinge of lubricant. |
| 3. To part with nippers or the screw-driver "moustaches" of a locking ring and, at the same time tapping with a soft drift on a holder, to bring down the hinge from shliyets (if necessary after that it is possible to remove a cover for replacement). |
| 4. To wash out the hinge in kerosene and to mark the mutual provision of a separator, holder and case. |
|
5. Accurately tapping with the mandrel (made of soft material) on a separator end face, to press through it and I will embrace to situation when the ball (or two next balls) leaves a path. |
| 6. The mandrel made of soft metal to squeeze out a ball from a separator and a similar way to take out other balls. |
|
7. To develop a separator with a holder in the plane, perpendicular to a hinge case end face so that two extended windows settled down against case ledges, and to take out a separator with a holder. |
|
8. Rotating a holder, to drown one of its ledges in the extended window of a separator and to roll out a holder. |
| 9. To carefully wash out details of the hinge and to check their state, paying special attention to polished surfaces of paths and spherical surfaces of a separator and balls. |
| 10. Existence of cracks, chips and traces of corrosion is inadmissible. At wear of working surfaces of racetracks more than and existence of the defects stated above to replace the hinge with 0,1 mm assembled. |
