10.2. Removal and driveshaft installation

Removal

 PERFORMANCE ORDER

  1. Block forward wheels, then поддомкратьте a back of the car and reliably establish it on axial support. Remove system of production of the fulfilled gases (see. Head System of production of the fulfilled gases). Remove a heat resisting guard of system of release.
  2. At the sliding coupling weaken the tightening plug (if it is provided) on some turns, but do not remove it.
  3. Latest models are not equipped with the tightening plug. With paint, a center punch or a chertilka put combination labels on a flange of transmission and the elastic coupling (or the forward kardanny hinge on some models), and also on the back kardanny hinge and an entrance flange of differential that at assembly to have possibility of installation of transmission in former situation...

... and also on the back kardanny hinge and an entrance flange of differential

  1. Give bolts and nuts of fastening of the elastic coupling (see an illustration) or the kardanny hinge (see an illustration) to a target flange of transmission. Yet do not separate the driveshaft from a flange.
  1. On models with CV JOINTS at first use a suitable jack to prop up transmission. Release fixing nuts and bolts of a back support of transmission (see. Head the Manual box of gear shifting (RKPP)), then move a support back and give six nuts and bolts of fastening of the CV JOINT to a transmission support. Give nuts and bolts on a back flange of the driveshaft (see an illustration above).
  1. Prop up the driveshaft at the central bearing and give bolts (are specified by shooters) on bearing assembly
  1. Incline the driveshaft down at the central bearing, then remove it from a centering finger on a transmission flange - remove as well the shlitsevy coupling if more place is required, but do not divide driveshaft section.

On models with a quencher of vibrations turn quencher assembly under 60 ° before removal it from a centering finger on a transmission flange.

  1. If are going to clean the shlitsevy coupling or to replace the rubber plug, mark both sections of the driveshaft before separating the coupling. After cleaning шлицов before assembly grease their disulfide - molybdenum greasing. If you divided driveshaft sections, without having marked them, collect the shlitsevy coupling so that kardanny hinges appeared in one plane. If after installation the driveshaft vibrates, means, you established it to sections incorrectly. In this case it is necessary to remove the driveshaft, to divide it in a place of the shlitsevy coupling, and to turn one section on 180 ° before installation.

Installation

Installation generally repeats removal procedure upside-down. However it is necessary to pay attention to the moments listed below.

 PERFORMANCE ORDER

  1. Apply a thin film a disulfide - molybdenum greasing on centering finger on a transmission flange.
  2. Place the driveshaft at first opposite to an entrance flange of differential, get it on centering finger on a transmission flange, then place the central bearing opposite to a finger and freely screw fixing bolts. Where CV JOINTS are established, make sure that laying is about a working condition, otherwise make replacement. Combine the labels put in the course of dismantle on a flange of the back kardanny hinge and an entrance flange of differential. Establish back section of the driveshaft in an entrance flange of differential by means of NEW самоконтрящихся nuts and tighten these nuts with demanded effort.

Do not use самоконтрящиеся a nut repeatedly.

  1. Combine the labels put at dismantle on a forward part of the driveshaft and connect the elastic coupling, the kardanny hinge or the CV JOINT to target shaft of transmission by means of new самоконтрящихся nuts. Tighten bolts with demanded effort.

Here various classes of bolts which are tightened with different efforts are used; the class of a bolt is designated on its head.


To avoid overloads of the elastic coupling during a tightening of bolts, hold a bolt a key and tighten a nut on the flange party.


It will be easier to establish bolts on the elastic coupling if to wind round it a big shlangovy collar and slightly to tighten it, having compressed the coupling.


  1. Make a pretightness of the central bearing, having advanced it forward on 4 ÷ 6 mm (for driveshafts with a sliding central element) or on 2 ÷ 4 mm (for shaft without a sliding element) from it not tightened situation, then tighten fixing bolts with demanded effort.
  1. On models with the CV JOINT remove a back arm of transmission forward and tighten fixing bolts. Clean a jack from under transmission.
  2. Tighten the tightening plug on the shlitsevy coupling.
  3. The rest of procedure of installation make as it should be, the return to removal.
