If during the movement of the car in turns knocks in the forward drive are heard, check hinges of equal angular speeds. If when rocking the side play is felt as a hand of a shaft of the drive or protective covers are torn, such hinge needs to be replaced. It does not make sense to disassemble the hinge practically. This laborious work, and at the torn cover the dirt which got to the hinge already put hinge details out of commission. It is impossible to replace hinge details separately therefore the most optimal solution — to replace the hinge assembled. Emergence of traces of lubricant on the hinge indicates that the cover is torn.

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

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

2. Clear details and examine the drive:

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

– the internal hinge has to move in the angular and axial directions with easy effort, at the same time should not be felt breakthroughs, jammings and radial side plays. 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 the drive of wheels should not be deformed. Replace the deformed shaft.

3. For replacement of the external hinge and its cover disconnect the screw-driver or have a bite bokorezam 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 one-time use, at assembly replace them new. As a rule, collars are included in the package of the new hinge.

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

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

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

Prevention Dismantling of the external hinge is not allowed.

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

Note At assembly replace a lock ring new. As a rule, the ring is included in the package 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 installation of the hinge replace a protective cover new. Usually the cover is included in the package of the new hinge.

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

Note In the absence of the lubricant recommended by manufacturer it is possible to use domestic molybdenic SHRUS-4 lubricant.

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

Prevention Before fixing of a cover of the hinge with a big collar delay the screw-driver edge of a cover to level air pressure 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 was done 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. Part short moustaches of a lock ring and remove the internal hinge from a shaft the same as it was done for the external hinge (see subitems 6 and 7).

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

Note At installation of the hinge replace a protective cover new. Usually the cover is included in the package of the new hinge.

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

Note At assembly replace a lock ring new. As a rule, the ring is included in the package of the new hinge.

20. Establish a cover of the internal hinge, put on a shaft the holder of a cover and a napressuyta the hinge blows of the hammer to a hinge holder through a drift from soft metal until fixing of a holder a lock ring.

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

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 by collars.

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