Removal and installation torsion beams of a back suspension bracket

Removal

PERFORMANCE ORDER

Prop up forward wheels противооткатными boots, поддомкратьте a back of the car and establish it on props. Remove back wheels.
On the models the Versatile person equipped with system of adjustment of a back road gleam uncover the right back combined lantern in a luggage space and through the valve pit pressure from system. Disconnect from the shock-absorber an air tube.
In car salon completely release the lever of a lay brake and remove from it a protective cover. Give an adjusting nut and remove it from primary section приводного a cable of a lay brake.

On models with disk brake mechanisms of back wheels a screw-driver wring out executive levers of a lay brake on supports and disconnect from them приводные cables. Release clamps and liberate covers of cables from basic arms on supports. Liberate cables from intermediate clamps on a connector of levers.

On models with back drum-type brake mechanisms disconnect short back cables from tips before brake drums.
On the models equipped ABS, liberate electroconducting of wheel gauges from clamps on the back party of naves and torsion to a beam.
On the models equipped with the valve-regulator of pressure in a contour of back brake mechanisms, disconnect a tension spring.
For the purpose of minimisation of losses of a hydraulic liquid uncover tank GTTS, enclose under it polyethylene, screw on a place and densely tighten.
Release штуцерные nuts and disconnect brake tubes from hoses from both parties of the car. Remove fixing plates. At once закупорьте the open ends штуцерных sockets for the purpose of hit prevention in dirt system.
Prop up a beam two тележечными jacks, for the purpose of loading distribution having laid heads of the last wooden брусками.

It is possible to manage and one jack, however then it is necessary to resort to the help of the assistant.

Turn out the bottom fixing bolts and disconnect both shock-absorbers from longitudinal levers of a suspension bracket.
Cautiously lower торсионную a beam as far as possible downwards and remove screw springs of a suspension bracket with rubber saddles. Pay attention that the top saddles are equipped by the built in chippers.

Check up reliability of fixing of a beam jacks, then turn out bolts of arms of fastening forward резинометаллических hinges of longitudinal levers of a beam to the car bottom.

Lower a beam and take it from under the car.
In case of need details of brake mechanisms can be removed from a beam (the Brake system see the Head). The description of procedure of removal ступичных assemblages see Removal and installation back ступичной assemblages.
In case of need remove from a beam резинометаллические hinges (Replacement резинометаллических hinges of longitudinal levers torsion beams see).

Installation

PERFORMANCE ORDER

Establish the components removed on a beam (corresponding Sections of the present Chapter and the Head Brake system see).
Check up a condition of a carving of permanently fixed nuts in arms of fastening of hinges, in case of need banish a carving a tap of the corresponding size.
Establish a beam on тележечный a jack () and get it under the car.
Lift a beam in regular position and screw fastening bolts резинометаллических hinges, - do not tighten while bolts definitively.
Expose a beam on a jack so that distance between basic surfaces of springs on levers and кузовных elements made 168 ±10.0 mm (models the Sedan and Hetchbek) / 198 ±10.0 mm (other models), then bolts of fixing arms of hinges and again tighten them, this time with demanded effort, then hold on them on the corners stipulated in Specifications.
Plant on springs rubber saddles and establish springs on a beam.
Lift a beam so that there was a possibility of installation of bolts of fastening of shock-absorbers.
Connect brake tubes to hoses, tighten штуцерные nuts with demanded effort, then establish fixing plates.
On the models equipped with the valve-regulator of pressure in back brake contours, establish a clamp and a spring and tighten a fixing bolt with demanded effort (Specifications to the Head Brake system see ).
On models with ABS fix electroconducting in intermediate clamps on a beam and connect it to wheel gauges.
On models with drum-type brake mechanisms of back wheels restore initial connection of short sections приводных cables.
On models with disk back brakes connect cables of a drive of a lay brake to executive on supports, - do not forget to fix cables in basic arms.
Pump over brake system (the Brake system see the Head).
Make adjustment of a drive of a lay brake (the Brake system see the Head), then establish on the lever a protective cover.
On the models the Versatile person equipped with system of adjustment of a back road gleam lift pressure in system to 0.8 bar, then adjust it according to degree of loading of the car and establish a cover of the back combined lantern.
Establish wheels and lower the car on the earth.
