4.2.2. Dismantling, check and assembly of an amortizatorny rack

By means of a flat screw-driver remove a protective cap of a rack.

Fig. 4.19. Compression of a spring of a rack

By means of the special tool (J38402, A-42) compress a rack spring so that impact on cups of a spring was minimum (fig. 4.19).

NOTE Do not apply the pneumatic tool (shock гайковерт).

Unscrew a nut of the top end of a rod of the shock-absorber.

Remove a dempfiruyushchy support of a rack, the top cup of a spring, a spring and a protective cover from a forward rack assembled.

Check the bearing of a dempfiruyushchy support of a rack on lack of wear or damage.

Check rubber details on absence of damages or deterioration of a technical condition.

Check a spring on lack of wear or deformation (a prosedaniye and decrease in rigidity).

Fig. 4.20. Shock-absorber check

Check the shock-absorber on lack of abnormal resistance to moving of a rod and extraneous noise (fig. 4.20).

Put forward a shock-absorber rod against the stop.

Fig. 4.21. An opening for production of gas

Drill an opening in a place noted "And" in drawing 4.21, and let out gas from the shock-absorber.

ATTENTION In itself gas is harmless, however at its exit from an opening the shaving which has remained after drilling therefore be careful can take off.

Fig. 4.22. Installation of the bottom pro-rate of a spring

Establish the bottom pro-rate of a spring so that ledges on it were combined with openings in the bottom cups of a spring (fig. 4.22).

Establish a protective cover on the shock-absorber.

By means of the special tool (J38402, A-42) compress a spring.

After complete compression of a spring establish it on the shock-absorber.

NOTE Establish a spring so that the identification label was located from a rotary fist.

Fig. 4.23. Installation of the top cup of a spring and dempfiruyuushchy support of a rack

Put forward a shock-absorber rod against the stop, establish the top cup of a spring and a dempfiruyuushchy support of a rack assembled (fig. 4.23).

NOTE Combine a flat part of a D-shaped opening of the top cup of a spring from a lysky bezrezbovy part of a rod of the shock-absorber.

Fig. 4.24. Labels of combination of rounds of a spring

Combine the top and bottom rounds of a spring with the corresponding dredging on the top and bottom cups of a spring of a rack, then temporarily tighten самоконтрящуюся a nut (fig. 4.24).

Remove the special tool.

Tighten самоконтрящуюся a nut the nominal moment of 50-70 N · m.

Put the specified greasing on the bearing of a dempfiruyushchy support of a rack and establish a protective cap.

ATTENTION Be careful when drawing greasing, do not allow hit it on a rubber part of a dempfiruyushchy support.

Recommended greasing: MS511-11 or equivalent.
