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

Before removal of components check up 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 release for one качок a body. For an estimation of a condition of screw springs some times rock the car for усадки components, then check up height of landing of a body (rating values — see an illustration the Estimation of a condition of screw springs) — the given springs are not subject to regenerative repair and should be replaced.


Estimation of a condition of screw springs

Hf — 815 mm

Hr — 855/846 mm (Specifications see)


Removal

 PERFORMANCE ORDER

  1. Поддомкратьте the car also establish it on props (the Scheme of an institution of props for car fixing in the lifted position see an illustration). Remove a 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 position of a rack concerning a rotary fist, then give fixing nuts and bolts of the bottom support of rack-mount assemblage.
  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 assemblage of a rack with a screw spring from the car, transfer it on a workbench and clamp in a vice with soft sponges.
  1. Slightly ослабьте a nut of a rod of the shock-absorber, then compress a screw spring by means of the special tool and definitively turn away a nut.
  1. Definitive отдавание nuts of a rod of the shock-absorber it is made after compression of a screw spring.
  1. Remove from rack-mount assemblage a screw spring.


Check

 PERFORMANCE ORDER

  1. Estimate smoothness of courses of compression and a rack stretching.
  1. Examine assemblage on presence 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 assemblage a screw spring (a flat end face upwards) and make sure of hit of its bottom end face прутка in reciprocal deepening in a saddle.
  1. Track, that the top saddle of a spring has appeared is developed by U-shaped cut to ДП the car and on one line with points of fastening of a rack to a rotary fist.
  1. The further installation is made in an order, the return to an order of dismantle of components. Track, that all fixture has been tightened with demanded effort.
