Replacement of cardan hinges

For implementation of this procedure the press or a big vice are required. It will be reasonable to send a shaft to a workshop where the cardan hinge can be replaced for rather small payment.

Remove the driveshaft (see the Section Removal and installation of driveshafts).

One-hinged cardan knot

 PERFORMANCE ORDER

  1. By means of small flat-nose pliers remove lock rings from a crosspiece.
  1. Supporting the driveshaft, place it or in a shpindelny press, or in the vice established on a strong workbench.
  2. Rest at the same time against a cover of one of bearings a piece of a pipe or a big replaceable face head of the same internal diameter, as a cover. From the opposite side establish a head of diameter slightly smaller than a cover. For replacement of a cover squeeze a vice or a press (the cover will drop out in a head of bigger diameter. Stop squeezing a vice (press) just before that as the cover finally will leave the holder of a crosspiece. For final extraction of a cover use big pincers.
  1. For a vypressovka of the cardan hinge from the holder of a crosspiece of the driveshaft, clamp the holder in a vice, having laid between covers of bearings and sponges of the last two replaceable heads (one, internal diameter more than diameter of a cover and another - outer diameter less than diameter of a cover); when tightening a vice the head of smaller diameter will push the cover in the holder, forcing out at the same time opposite in a head of bigger diameter).
  1. Trade heads places and similarly squeeze out a cover of the opposite bearing.
  2. Fill lubricant new bearings of the cardan hinge. Usually the instruction for their greasing is put to a remnabor for service of cardan hinges - try to adhere to it strictly.
  3. Establish a crosspiece in the holder and partially fill in him a cover of one of bearings. If the established crosspiece is equipped with the lubricant union, track that it was turned in the right direction (to the driveshaft).
  4. Fill a crosspiece in a bearing cover, then partially enter the second cover. Level a crosspiece and press covers of bearings on the places in the holder, watching to damaging boots.
  5. Establish lock rings. If at installation of rings there are difficulties, rigidly knock with the hammer on the holder of a crosspiece on a shaft. At the same time the holder's ears slightly will contract, having provided a possibility of landing of rings in the flutes.
  1. If the lock ring does not sit down in the flute, tap the holder of a crosspiece the hammer - it will weaken internal tension and slightly will squeeze the holder's ears (the same procedure should be made if after assembly rotates too hardly).
  1. Install the lubricant union and fill the hinge lubricant. You do not enter too much lubricant as it is fraught to expression of cuffs into the hinge.
  2. Install into place the driveshaft. Tighten flange bolts with the required effort.

Two-hinged cardan knots

Use the procedure stated above, however taking into account that it has to be repeated also for the second hinge of assembly.

Replacement of two-hinged cardan knot is made assembled - it is not necessary to do attempts of replacement of only a half of knot even if only one of its crosspieces is worn-out.

Hinges of equal angular speeds (CV hinges) (the model of 1995 of the issue equipped with the driveshaft of the Third type)

CV hinges of driveshafts of the Third type are not subject to replacement in an individual order. In case of damage of the hinge or its protective cover it is necessary to replace all assembly of the driveshaft (Section Check of a Condition of the Transmission Line). Pay attention to need of measurement (and, in case of need, adjustments) a new shaft before it will be possible to start operation of the car (see also Section Check of a Condition of the Transmission Line).
