6.3.4. Replacement of hinges of equal angular speeds

If during car movement in turns knocks in a forward drive are audible, check hinges of equal angular speeds. If when rocking by a hand of a shaft of a drive it is felt люфт or protective covers are torn, it is necessary to replace such hinge. To assort the hinge practically it is not meaningful. This work labor-consuming, and at the torn cover the dirt which has got to the hinge already put hinge details out of commission. To replace hinge details separately it is impossible, therefore the most optimum decision — to replace the hinge assembled. Emergence of traces of greasing on the hinge specifies that the cover is torn.

It be required to you: бокорезы (or a screw-driver with a flat edge), a stripper of lock rings (or пассатижи with thin long sponges), small beards, a hammer.

1. Remove a drive of a forward wheel in collecting (see. «Removal and installation of drives of forward wheels»).

2. Clear details and examine a drive:

– the external hinge of equal angular speeds should turn with easy effort without breakthroughs and jammings, radial and axial люфтов. At their existence replace the hinge;

– the internal hinge should move in the angular and axial directions with easy effort, thus should not be felt breakthroughs, jammings and radial люфтов. Otherwise replace the internal hinge;

– protective covers of external and internal hinges should not have cracks and gaps. Replace the damaged covers;

– the shaft of a drive of wheels should not be deformed. Replace the deformed shaft.

3. For replacement of the external hinge and its cover disconnect a screw-driver or have a bite бокорезами the lock of a collar of fastening of a big cover of the external hinge...

4.... also remove a collar.

Note Collars of fastening of protective covers of hinges of equal angular speeds of disposable use, at assembly replace them new. As a rule, collars enter into a set of the new hinge.

5. Shift a protective cover from the hinge case...	6.... dissolve short moustaches of a lock ring of fastening of the hinge on a drive shaft, shift the hinge on shlitsa of a shaft...

Note The lock ring of fastening of the external hinge on a drive shaft (for descriptive reasons greasing is removed from the hinge) is so located.

7.... also remove it from a shaft.

Prevention Dismantling of the external hinge is not allowed.

8. Take a lock ring from a pro-point of a holder of the hinge.

Note At assembly replace a lock ring new. As a rule, the ring enters into a set of the new hinge.

9. Remove a small collar of a cover of the external hinge the same as removed a big collar (see item 3).	10. Remove a protective cover.

Note At hinge installation a protective cover replace new. Usually the cover enters into a set of the new hinge.

11. Before installation of the new external hinge fill his cavity with greasing (if the hinge was not greased by the manufacturer) in number of about 100 g. And at first fill the hinge case, and then the remained quantity evenly distribute in гофрах a cover.

Note In the absence of the greasing recommended by manufacturer, it is possible to use domestic molybdenic CV JOINT-4 greasing.

12. Establish a cover of the external hinge and the hinge as it should be, the return to removal. At hinge installation on a shaft напрессовывайте the hinge in hammer blows on a hinge shaft through a drift from soft metal till fixing of a holder of the hinge by a lock ring.

Prevention Before fixing of a cover of the hinge by a big collar delay a screw-driver cover edge to level pressure of air in and outside of a cover.

13. For replacement of the internal hinge and its cover remove collars of fastening of a cover of the hinge to its case and to a shaft the same as it did at removal of the external hinge.

14. Shift a cover on a shaft, having removed it from the holder on the hinge case.	15. Clamp the internal hinge in a vice and press the holder of a cover from its case.

16. Move the holder on a shaft so that access to a lock ring of fastening of a holder of the hinge on a shaft opened.

17. Dissolve short moustaches of a lock ring and remove the internal hinge from a shaft the same as it did for the external hinge (see subitem 6 and 7).

18. Remove from a shaft the holder and a cover.

Note At hinge installation a protective cover replace new. Usually the cover enters into a set of the new hinge.

19. Take a lock ring from a pro-point of a holder of the hinge.

Note At assembly replace a lock ring new. As a rule, the ring enters into a set of the new hinge.

20. Establish a cover of the internal hinge, put on a shaft the holder of a cover and напрессуйте the hinge in hammer blows on a hinge holder through a drift from soft metal till holder fixing by a lock ring.

Notes The new hinge can be completed already napressovanny on its case by the holder of a cover. In this case to establish the holder on a shaft separately it is not required. Before installation of the new internal hinge fill his cavity with greasing (if the hinge was not greased by the manufacturer) in number of about 100 g. And at first fill the hinge case, and then the remained quantity evenly distribute in гофрах a cover.

21. Napressuyte on the hinge case the holder of a cover, if it not напрессован on the case of the new hinge.

22. Fix a cover on the holder and on a shaft collars.

Prevention Before fixing of a cover of the hinge by a big collar delay a screw-driver cover edge to level pressure of air in and outside of a cover.
