Dismantling of a power shaft and replacement of a protective cover
|
|
Depending on an engine/check point combination the internal hinge is executed as the hinge of equal angular speeds or the Tripode hinge. The Tripode hinge has 3 rollers which are displaced on a corner 120 ° in relation to each other instead of 6 balls and are located on «Tripode» star. |
External hinge
Removal
|
|
Remove a shaft, address to the Section Removal and installation of a power shaft.
Clamp a shaft through protective slips in a vice.
Remove collars and shift back a protective cover.
|
Screw press the screw (3207) with directing for carving M14/M16 in a pin of the hinge so that to remove the hinge from a shaft.
|
|
Remove a lock ring.
|
|
Installation
|
|
Put on a shaft a cover.
|
|
|
The cover and place of its landing on a shaft should not have some greasing. |
|
Establish a new lock ring.
Enter into an internal part of the hinge of 50 g of greasing.
|
Screw in the hinge the screw which was earlier in work, as is shown in an accompanying illustration.
|
|
Napressuyte the hinge by means of a plastic hammer on a shaft so that fixed a lock ring.
Turn out the old screw.
Enter into the hinge of 40 g of greasing from a cover.
|
Grease the external hinge.
|
|
|
|
The cover at its putting on on the case of the hinge is often compressed. Thus in the hinge there is a razryazheniye which leads to cover cave-in (an arrow on an accompanying illustration). Therefore at cover installation by means of a screw-driver on small diameter fill the hinge with air so that to provide pressure alignment. |
|
By means of special pincers, for example, HAZET 1847-1 compress collars on big and small diameters of the hinge.
|
|
|
Cover from plastic
|
|
Compress collars on big and small diameters.
|
|
External hinge: It is necessary to apply to a clip of collars (the alloyed steel) the special pincers of HAZET 1847 shown on an illustration, otherwise necessary force of compression it is not reached. It is necessary to establish pincers, as is shown in an illustration. Working edges of pincers should be in corners (In). In this situation the screw (And) is tightened by the moment 20Нм. The collar clip on small diameter is carried out similarly.
|
|
|
The carving of the tightening screw of pincers should have an easy course, otherwise it is necessary to grease it with MoS2 greasing previously. If the carving has a heavy course, for example, owing to pollution the necessary moment of a tightening of the screw is not reached. |
|
|
Internal hinge of equal angular speeds
Removal
|
|
Uncover by means of the corresponding drift.
|
|
Remove a lock ring.
|
|
Remove greasing from the hinge and mark position of the hinge concerning a shaft.
|
Clamp a shaft for the hinge in a vice, as is shown in an accompanying illustration.
|
|
The assistant should hold a shaft horizontally not to damage it.
By means of a small flat chisel slightly turn in an edge of a cover (shooter).
Establish a cover into place by means of the corresponding opravka.
|
Press the hinge from a shaft.
|
|
Remove a cover with a cover.
|
|
Installation
|
|
Put greasing on a pure surface of inside of a cover (the shaded surface on an accompanying illustration). Put the roller from hermetic in width of 2-3 mm around openings from the inside. HUNDRED AUDIS apply for this purpose A2 hermetic D 454 300.
|
|
|
|
The shaft, cover and adjacent surface should not have some greasing. |
|
Put on a shaft a new cover with a cover.
Enter into a cover of 85 g of greasing.
|
Fix the hinge a sticky tape (an arrow on an accompanying illustration) that it did not break up.
|
|
Napressuyte the hinge against the stop on the corresponding press. HUNDRED AUDIS apply for this purpose the special tool shown on an illustration.
|
|
|
Establish a hinge nave a facet on internal diameter (shlitsa) on the hinge. The tool 40-204 A and an interface surface on a shaft should not have some greasing. |
|
Establish a new lock ring.
Enter 35 g of greasing through paths for balls into the hinge.
|
Expose by means of screws (arrow) a cover with a cover in relation to openings.
|
|
|
|
It is necessary to expose very precisely since after assembly it cannot be made. |
|
Establish into place a cover with a cover by means of a plastic hammer.
At once eliminate the acted greasing.
|
Expose a new cover with (arrow) screws in relation to openings under bolts.
|
|
|
|
It is necessary to expose very precisely since after assembly it cannot be made. |
|
Establish into place a cover with a cover by means of a plastic hammer.
At once eliminate the acted greasing.
Establish into place a power shaft, address to appropriate section.
