4.2.2. Dismantling, check and assembly of a damping rack

By means of the 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) squeeze a rack spring so that impact on cups of a spring was minimum (fig. 4.19).

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

Turn off a nut of the top end of a rod of the shock-absorber.
Remove the damping rack support, the top cup of a spring, a spring and a protective cover from a forward rack assembled.

Check
Check the bearing of the damping rack support for lack of wear or damage.
Check rubber details for absence of damage or deteriorations in technical condition.
Check a spring for lack of wear or deformation (a flash and decrease in rigidity).

Fig. 4.20. Check of the shock-absorber


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

Utilization of a rack
Put forward a shock-absorber rod against the stop.

Fig. 4.21. An opening for production of gas


Drill an opening in the place noted "And" in the figure 4.21, and produce gas from the shock-absorber.

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

Assembly

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


Establish the lower pro-rate of a spring so that ledges on it were combined with openings in lower cups of a spring (fig. 4.22).
Install a protective cover on the shock-absorber.
By means of the special tool (J38402, A-42) squeeze a spring.
After full compression of a spring install it on the shock-absorber.

NOTE
Establish a spring so that the identification tag 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, install 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. Tags of combination of rounds of a spring


Combine the top and lower rounds of a spring with the corresponding dredging on the top and lower 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.
Apply the specified lubricant on the bearing of the damping support of a rack and establish a protective cap.

ATTENTION
Be careful when putting lubricant, do not allow hit it on a rubber part of the damping support.

The recommended lubricant: MS511-11 or equivalent.
