Dismantling of a power shaft and replacement of a protective cover

Depending on a combination the engine/kpp the internal hinge is executed as the hinge of equal angular speeds or hinge "Tripode". Hinge "Tripode" has 3 rollers which are displaced on a corner 120 ° in relation to each other instead of 6 balls and are located on a star «Tripode».

The external hinge

Removal

 PERFORMANCE ORDER

  1. Remove a shaft, address to Section Removal and power shaft installation.
  2. Clamp a shaft through protective overlays in a vice.
  3. Remove collars and shift back a protective cover.
  1. Screw press the screw (3207) with directing for carving М14/М16 in a hinge pin so that to remove the hinge from a shaft.
  1. Remove a lock ring.

Installation

 PERFORMANCE ORDER

  1. Put on a shaft a cover.

The cover and place of its landing on a shaft should not have some greasing.

  1. Establish a new lock ring.
  2. Enter into an internal part of the hinge 50 г greasings.
  1. Screw in the hinge the screw which was earlier in work, as is shown in an accompanying illustration.
  1. Напрессуйте the hinge by means of a plastic hammer on a shaft so that the lock ring was fixed.
  2. Turn out the old screw.
  3. Enter into the hinge 40 г greasings from outside a cover.
  1. Grease the external hinge.

Observe the established quantity of greasing, address to Specifications.

The cover at its putting on on the hinge case is often compressed. Thus in the hinge arises разряжение which leads to cover cave-in (an arrow on an accompanying illustration). Therefore at installation of a cover by means of a screw-driver on small diameter fill the hinge with air so that to provide pressure alignment.

  1. By means of special pincers, for example, HAZET 1847-1 compress collars on the big and small diameters of the hinge.

Cover from plastic

 PERFORMANCE ORDER

  1. Compress collars on the big and small diameters.
  1. The external hinge: it is necessary to apply To a clip of collars (the alloyed steel) the special pincers HAZET 1847 shown on an illustration, otherwise necessary force of compression it is not reached. Pincers are necessary for establishing, as is shown in an illustration. Working edges of pincers should be in corners (). In this position the screw () 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 greasing MoS2 preliminary. If the carving has a heavy course, for example, owing to pollution the necessary moment of a tightening of the screw is not reached.

Removal

 PERFORMANCE ORDER

  1. Uncover by means of corresponding выколотки.
  1. Remove a lock ring.
  1. Remove greasing from the hinge and mark position of the hinge concerning a shaft.
  1. Clamp a shaft for the hinge in a vice, as is shown in an accompanying illustration.
  1. The assistant should hold a shaft horizontally not to damage it.
  2. By means of a small flat chisel slightly turn in an edge of a cover (arrow).
  3. Establish a cover into place by means of corresponding оправки.
  1. Press the hinge from a shaft.
  1. Remove a cover with a cover.

Installation

 PERFORMANCE ORDER

  1. Put greasing on a pure surface of an inside of a cover (the shaded surface on an accompanying illustration). Put the platen from hermetic in width of 2-3 mm around apertures from the inside. HUNDRED AUDI apply for this purpose hermetic D 454 300 A2.

The shaft, cover and adjoining surface should not have some greasing.

  1. Put on a shaft a new cover with a cover.
  2. Enter into a cover 85 г greasings.
  1. Fix the hinge a sticky tape (an arrow on an accompanying illustration) that it did not break up.
  1. Напрессуйте the hinge against the stop on a corresponding press. HUNDRED AUDI apply for this purpose the special tool shown on an illustration.

Establish a nave of the hinge a facet on internal diameter (шлицы) on the hinge. 40-204 And and an interface surface on a shaft greasings should not have the tool.

  1. Establish a new lock ring.
  2. Enter 35 г greasings through paths for balls into the hinge.
  1. Expose by means of screws (arrow) a cover with a cover in relation to apertures.

It is necessary to expose very precisely since after assemblage it cannot be made.

  1. Establish into place a cover with a cover by means of a plastic hammer.
  2. At once eliminate the acted greasing.
  1. Expose a new cover with (arrow) screws in relation to apertures under bolts.

It is necessary to expose very precisely since after assemblage it cannot be made.

  1. Establish into place a cover with a cover by means of a plastic hammer.
  2. At once eliminate the acted greasing.
  3. Establish into place a power shaft, address to corresponding Section.
