Removal

 PERFORMANCE ORDER

  1. Деактивируйте SRS (the Electric equipment see the Head).
  2. Result forward wheels of the car in rectilinear position.
  3. Remove a steering wheel (Removal and steering wheel installation see).
  4. With the help кернера mark adjusting position U-shaped карданного the hinge.
  5. Turn out the bottom coupling bolt шарнирной assemblages.
  6. Remove the top and bottom sections of a casing of a steering column.
  7. Remove a cable of blocking of switching АТ (the line see Head Transmissionnaja).
  8. Remove a cable of the indicator of position АТ.
  9. Disconnect electroconducting подрулевых switches, the lock of ignition and a spiral cable drum.
  10. Remove assemblage of the combined switch (Removal and installation of assemblage combined подрулевых switches see).
  11. Remove the left bottom section of furnish of the panel of devices.
  12. Turn out bolts of the bottom basic arm of a column and fastening bolts pylnika/floor panels.
  13. Turn out bolts of fastening of the top basic arm of a column.
  14. Remove a column, accurately having involved it in car salon.


Check

 PERFORMANCE ORDER

  1. If infringement of smoothness of rotation of a steering wheel took place, estimate degree of deterioration of bearings of a steering column.
  2. Check up presence in greasing bearings.
  3. Examine a sleeve of the case of a column on presence of deformations and other mechanical damages.
  1. If the car had an accident, measure geometrical parametres of a column and the top hinge.

    A — the Verifying sizes of a steering column and top карданного the hinge

    L 1 — Length of the top shaft of a steering column
    L 2 — Length of the bottom shaft of a steering column

    B — the Verifying size top карданного the hinge of a steering column

A.

B.

The top hinge is located between редукционной assemblage of a steering drive and the bottom shaft of a steering column.

  1. If results of measurements fall outside the limits admissible ranges (Specifications see), replace a column in gathering.
  1. Check up the adjusting sizes приводного the mechanism of adjustment of an inclination of a column. Compare results of measurements to requirements of Specifications, in case of need make column replacement.


Installation

 PERFORMANCE ORDER

  1. Make sure that forward wheels of the car still are in rectilinear position.
  2. From salon pass assemblage of a steering column in an aperture in a car floor. Make sure of correctness of combination of adjusting labels of a shaft of a gear wheel and U-shaped карданного the hinge.
  1. Connect the bottom hinge to a gear wheel shaft, — track, that the coupling bolt has appeared will develop to cut on a shaft.
  1. Establish the top and bottom basic arms of a column, and also bottom duster with a fixing flange.
  2. By hand tighten all bolts of the bottom arm and a fixing collar.
  3. Tighten a bolt bottom карданного the hinge.
  4. Tighten nuts and bolts of the top and bottom arms with demanded effort.
  5. Restore initial connection of electroconducting.
  6. Establish sections of a casing of a steering column and a steering wheel (Removal and steering wheel installation see).
  7. Tighten a nut of fastening of a steering wheel with demanded effort.
  8. Establish the module of a pillow of safety / a horn overlay. Check up serviceability of functioning of a sound signal, the lock of ignition and подрулевых switches.
  9. Check up correctness of centering of a steering wheel (Checks and steering wheel adjustments see).
  1. Check up serviceability of functioning of the mechanism of adjustment of an inclination of a column and its adjusting sizes.
