Dismantling of power shafts and replacement of protective covers

The external hinge of equal angular speeds does not understand. In the presence of any damages a shaft replace entirely. Both covers act in film from the inside. At long operation it is recommended to replace both covers.



1. Remove a back power shaft, address to appropriate section.

2. Weaken carving collars, cut coupling collars and replace them at installation with the carving.

3. Uncover a cover of the internal hinge at the case and shift towards a power shaft as follows:

· Clamp a power shaft in a vice;
· Saw through a hacksaw a cover cover at an angle about 45 ° so that to receive an angular groove.

Thus do not damage the hinge case;

· Raise a screw-driver the made an incision top a little;
· Take a cover cover tweezers for the acting end screw so that the cover of a cover separated from the hinge case.

At a navorachivaniye watch that the power shaft did not drop out of a sharnirny ring if details are not marked.

4. Wipe a rag hinge greasing.

5. Vypressuyte a power shaft from the internal hinge on the press. As a lining apply half rings which lean on a hinge fillet. Half rings have the next sizes:

External diameter of 50 mm,
Internal diameter of 33 mm,
Length of 50 mm.

6. Remove a cover of the internal hinge from a power shaft.
7. If necessary remove collars of a cover of the external hinge, uncover a cover and remove a cover through a shaft. Thus watch that dirt did not get to the hinge. Before removal of a cover remove greasing from the interior of a cover and enter it into the hinge.
8. If necessary wash out the hinge in gasoline and check holder paths on wear, and also on existence of damages. In the presence of strong wear it is necessary to replace all hinge.
9. Clear a back power shaft.

7. Remove the assembly plug and a protective film.
8. Put on a shaft the internal hinge.

9. Clamp a shaft around a cover fillet the tightening adaptation or in a vice with protective sponges.

10. Press the hinge of equal angular speeds by means of a drift against the stop in an adjacent surface of a back power shaft. Then напрессуйте the hinge so that the ledge of a back power shaft made 4.2 mm.
11. Clamp a shaft in a vice so that the nave of the hinge adjoined to half rings. Fix a shaft stamping. Thus make new stamping, in the middle between two already available. The corresponding tool is applied to stamping with a working part in width of 5-6 mm.

 For avoidance of damages of paths of a kacheniye, for example, owing to a rebound of the tool it is necessary to carry out stamping as it is possible closer to shlitsa.

12. Remove the tightening adaptation.
13. Put on against the stop a cover cover the corresponding ring of the hinge.

Thus do not grease a sealing ring, otherwise later the cover will be turned on a hinge ring. If necessary the ring can be put into place by easy blows of a plastic hammer.

14. Fix a cover cover in four blows on a circle with a step 90 ° in a groove of the case of the hinge. Then pull a cover by means of a hammer in a groove of the case of the hinge. Thus watch the correct provision of a cover of a cover.
15. Fill cavities and covers of internal and external hinges of equal angular speeds with MERСEDES greasing in volume of 100 g. Watch that dirt did not get to hinges.
16. Put on a protective cover a cover so that the sealing ledge of a cover was between ledges of a cover of a cover.
17. Put on covers in small diameter a thickening of a power shaft so that after installation it was not visible flutes of a power shaft. The cover thickening thus is fixed in the first flute of a shaft. Put on collars and fix them.
