Removal and installation

Before removal of the steering mechanism remove a steering wheel since otherwise it is possible to damage a spiral spring.


 PERFORMANCE ORDER

  1. Establish wheels in the provision of rectilinear movement.
  2. Remove a steering wheel (see. Section Removal, installation, dismantling and assembly of a steering column).
  3. Disconnect from rotary fists tips of steering drafts (see. Door section).
  4. Disconnect assembly of an intermediate shaft (see. Section Removal, installation, dismantling and assembly of a steering column).
  5. Turn out a bolt and remove two collars.
  6. Disconnect from the steering mechanism delivery and returnable tubes.
  7. Turn out two bolts of fastening of assembly of the steering mechanism and remove it.

Do not damage returnable tubes.

  1. Installation is made upside-down. After installation check corners of installation of forward wheels.

Dismantling

 PERFORMANCE ORDER

  1. Remove two returnable tubes with four sealing rings from assembly of the steering mechanism.
  1. Clamp assembly of the steering mechanism in a vice.
  1. Put adjusting labels on steering drafts and on their tips then give lock-nuts and remove tips.
  2. Weaken collars and clips of protective covers and remove covers and their fixture.

Measure the left and right covers that then to establish them on former places.


  1. Accurately расчеканьте fixing washers.
  1. Keeping draft a wrench, remove it by means of the special adaptation.

Measure the left and right drafts that then to establish them on former places.

  1. Remove fixing washers.
  2. Turn out an adjustable spanner a lock-nut of a cover of a spring of a directing lath and uncover, a spring and directing laths.
  3. Uncover cases of the steering mechanism.
  4. Holding a shaft of the control valve, give a being self-blocked nut.
  5. Put adjusting labels on assembly of the control valve and on the case of the steering mechanism.
  6. Turn out two bolts take out the case with assembly of the control valve.
  7. Remove from the case of the steering mechanism laying of the control valve.
  8. Wind with a vinyl tape a gear part of assembly of the control valve not to damage an epiploon edge.
  9. Vypressuyte assembly of the control valve together with an epiploon.
  10. Remove from assembly of the control valve an epiploon.
  11. Put adjusting labels on a bracket of No. of 2 assemblies of the steering mechanism and on its case.
  12. Wring out a screw-driver a clip of a bracket No. 2 and remove it
  13. Remove consolidation from a bracket No. 2.
  14. Turn a stopper clockwise so that through a technological opening the wire end was visible, then turn a stopper counter-clockwise and remove it together with a wire.
  15. Beat out a lath with the plug from the case of the steering mechanism, remove from a lath the plug and remove from the plug a sealing ring.
  16. Vypressuyte epiploon of their case of the steering mechanism.
  17. Check radial palpation of a lath and wear of its teeths and compare result to requirements of Specifications of Head the Suspension bracket and a steering. If necessary replace a steering rack.
  18. Assembly is made upside-down. Pay attention to the next moments:
    • Grease the surfaces designated on an illustration Components of the steering mechanism by white shooters, GUR liquid, and the surfaces designated by black shooters, - greasing on the basis of MoS 2;
    • Establish epiploons in the correct situation, do not confuse their party;
    • At installation of a stopper turn it on a corner 450 ± 50 hail.
    • Use new laying and sealing rings, самоконтрящуюся a nut and lock-nuts;
    • Tighten fixture with demanded efforts;
    • Grease with Three Bond 1344 hermetic a carving of a cover of the case of the steering mechanism, a carving of a cover of a spring of a directing lath and a carving of its lock-nut;
    • Regulate a pretightness of the steering mechanism;
    • After a tightening of a lock-nut of a cover of a spring of a directing lath check a pretightness of the steering mechanism;
    • Before installation of covers make sure that the opening in a lath is not hammered by greasing;
    • Tighten collars of fastening of covers;
    • Tighten lock-nuts of fastening of tips of steering drafts after adjustment of convergence of forward wheels.
