After removal of a sector shaft do not allow shift of the intensifying piston or a worm shaft. |
Having carefully hooked, remove a boot from an end face of a case of the steering mechanism from a soshka. Will throw out a boot.
Remove a lock ring and take the big remote plug, having accurately hooked it the suitable lever.
Carefully take an epiploon from a case of the steering mechanism - do not scratch the lever a condensed surface of a case.
Key of the TORX E10 type give bolts of fastening of a back cover.
Carefully remove a back cover together with the intensifying piston and worm shaft from a case of the steering mechanism. Try not to allow shifts of components in order to avoid drop-out of circulating balls.
|
|
Manufacturers of cars insist, that in case of excess by a gap between the piston and a back cover of size of 35 mm replacement of assembly of the piston with worm shaft was made. |
Check a condition of roller bearings, bearings of a worm shaft, a sector shaft and assembly of a worm shaft with the intensifying piston. Replace excessively worn-out and damaged components.
|
|
Components of the steering mechanism
Assembly
Assembly is made as it should be, the return to a dismantle order.
|
|
Replacement of sealing rings, remote plugs, epiploons, lock rings and washers should be made without fail each time when dismantling the steering mechanism. It means that for performance of assembly of the mechanism it is necessary to get the special remnabor containing all necessary replaceable components. |
|
|
Before assembly grease all components with hydraulic liquid.
Grease with suitable hermetic a new epiploon of a back cover and establish and plant it in a case of the steering mechanism by means of the piece of a pipe leaning on external perimeter of an epiploon. Track, that the epiploon appeared will turn the main sponges to the intensifying piston.
Establish in a back cover new sealing and teflon rings. For temporary fixing grease rings with technical vaseline.
Establish in a case of the steering mechanism a worm shaft, the intensifying piston and a back cover. Try not to damage a teflon ring at a piston end face. Track that all sealing rings were established on the places.
Screw bolts of fastening of a back cover and tighten them in a diagonal order in two-three stages with final effort of 26 ÷32 of Nanometer.
|
|
The intensifying piston should be in normal working situation and not to be warped. |
Grease a new epiploon of a sector shaft outside on perimeter with suitable hermetic, then plant it perpendicularly in a case of the steering mechanism by means of a piece of a pipe which should rest against the external region of an epiploon. Moderately grease are flexible an epiploon technical vaseline. Establish in a case of the steering mechanism the big remote plug and fix it a lock ring. Track, that the lock ring appeared is turned by the rounded edge to an epiploon.
|
|
On some models the epiploon party with the rounded edge is marked with an identification label in the form of R letter. |
Establish in a case of the steering mechanism a new boot, having planted it by means of the piece of a pipe resting against external of edge of a boot. Moderately grease boot sponges with technical vaseline.
|
|
Check size axial люфта a sector shaft (see an accompanying illustration), in case of need execute adjustment:
|
Clamp a sector shaft in a vice with soft sponges.
Establish a tsiferblatny measuring instrument a plunzher to an end face of the adjusting screw, then move the screw up-down for all length of its course and consider instrument readings. The nominal size axial люфта a sector shaft makes 0.01 ÷ 1.05 mm.
In case of need take the adjusting screw from a shaft and establish new adjusting washers of the demanded thickness. If it is not possible to achieve nominal size axial люфта, replace the adjusting screw.
Establish on a cover of a sector shaft a new sealing ring. Moderately grease it with technical vaseline. By means of the sharp tool of the small size remove a sealing ring from a lock-nut of the adjusting screw of a sector shaft. Using a blunt tool establish a new sealing ring, previously having greased it with technical vaseline.
Turn a worm shaft for a drive of the intensifying piston in rectilinear situation.
Wind shlitsa of a sector shaft with an adhesive tape.
Turn the intensifying piston teeth up, to the top part of a steering box, at an angle about 10 ° ÷ 15 ° for a guarantee of free installation of a sector shaft.
Establish in a case a sector shaft. Track, that the intensifying piston remained in the central situation.
Screw bolts of fastening of a cover of a sector shaft and tighten them in a diagonal order in two-three stages with final effort of 26 ÷ 32 Nanometers.
|
Clamp assembly of the steering mechanism in a vice approximately under a normal adjusting corner and check effort of its provorachivaniye.
|
Several times turn a worm shaft from an emphasis against the stop for a usadka of components of the steering mechanism
|
|
If at rotation of a worm shaft breakthroughs take place and zakusyvaniye points, as appropriate correct position of the adjusting screw. |
By means of a sensitive dinamometrichesky natural by a suitable nozzle measure effort of a provorachivaniye of a worm shaft. Measurement is made from the rectilinear provision of a shaft. The nominal rate makes 0.59 ÷ 1.34 Nanometers.
|
|
If the suitable nozzle near at hand is not available, it is possible to wind the shaft end with an adhesive tape and to use densely sitting down polygonal face head. |
Repeat check procedure after a provorachivaniye of a worm shaft on 360 ° from the central situation. This time the nominal rate makes on 0.2 ÷ 0.4 Nanometers less specified above.
If the effort of a provorachivaniye of a worm shaft gets to the stipulated values, tighten a lock-nut with effort of 34 ÷ 40 Nanometers, holding thus the adjusting screw motionlessly.
At an exit of effort of a provorachivaniye of a shaft out of admissible limits, correct as appropriate position of the adjusting screw. If to achieve effort hit in norm it is not possible, assembly of the steering mechanism should be replaced.
Establish assembly of the steering mechanism on the car.
|
|
Models of late years of release (since 1992) The order of performance of procedures stated above remains in force taking into account the following remarks:
|
|
- From assembly of the steering mechanism the boot of a sector shaft, a lock ring and the remote plug are eliminated. Are also cleaned a sealing ring of a lock-nut of the adjusting screw with a washer.
- Between an external epiploon of a sector shaft and the roller bearing in a case the additional flexible epiploon is established. This epiploon should be put by the equipped flute the party to the bearing.
- The flexible epiploon is established also on a cover of a sector shaft. The party equipped with a flute should be turned to the bearing.
