10.7. Removal, check of a condition and installation of screw springs and rack-mount assemblies of a forward suspension bracket

Before removal of components check a condition of shock-absorbers and screw springs on the car standing on the earth. Serially press on each of car corners — serviceable shock-absorbers provide corner return at an otpuskaniye for one muscleman a body. For an assessment of a condition of screw springs several times rock the car for a usadka of components, then check height of landing of a body (nominal rates — see an illustration the Assessment of a condition of screw springs) — the given springs are not subject to regenerative repair and should be replaced.


Assessment of a condition of screw springs

Hf — 815 mm

Hr — 855/846 mm (see. Specifications)


Removal

 PERFORMANCE ORDER

  1. To Poddomkratta the car also establish it on props (see an illustration the Scheme of an institution of props for car fixing in the lifted situation). Remove the corresponding forward wheel.
  2. Disconnect from a rack a bar of the stabilizer of cross-section stability.
  3. Prop up I will lower the cross-section lever of a suspension bracket.
  1. Mark the provision of a rack of rather rotary fist, then give fixing nuts and bolts of the bottom support of rack-mount assembly.
  2. Release nuts of fastening of the top support of a rack to a car body — do not turn on a nut of fastening of a rod of the shock-absorber.
  1. Remove rack assembly with a screw spring from the car, transfer it on a workbench and clamp in a vice with soft sponges.
  1. Slightly weaken a nut of a rod of the shock-absorber, then compress a screw spring by means of the special tool and finally unscrew a nut.
  1. The final otdavaniye of a nut of a rod of the shock-absorber is made after compression of a screw spring.
  1. Remove from rack-mount assembly a screw spring.


Check

 PERFORMANCE ORDER

  1. Estimate smoothness of courses of compression and stretching are resistant.
  1. Examine assembly on existence of signs of development of leaks.
  1. Make sure of absence on the piston of cracks, deformations and other mechanical damages.
  2. The faulty rack is subject to replacement.


Installation

 PERFORMANCE ORDER

  1. Plant on rack-mount assembly a screw spring (a flat end face up) and make sure of hit of the bottom end face its prutka in reciprocal deepening in a saddle.
  1. Track, that the top saddle of a spring appeared is developed by U-shaped cut to DP of the car and on one line with points of fastening are resistant to a rotary fist.
  1. Further installation is made as it should be, the return to an order of dismantle of components. Track, that all fixture was tightened with demanded effort.
