Removal, dismantle and installation of rack transfer

 The models of cars considered in the present manual are equipped with system of additional safety (SRS). Before starting performance of any works near the block of a safety cushion, a steering column or the dashboard, disconnect SRS in order to avoid getting injured at its casual operation (see the Head Onboard electric equipment). It is easy to distinguish an electrical wiring of a chain of SRS on yellow color of isolation. In order to avoid damage of the SRS system, Track that the steering shaft was not turned after removal of a steering wheel. Block a column the ignition key at the rectilinear provision of forward wheels.

REMOVAL

 PERFORMANCE ORDER

1. Details of installation of the steering mechanism are presented on an illustration.

2. Park the car with the forward wheels developed in rectilinear situation. Disconnect a negative wire from the battery. On the models equipped with safety cushions disconnect also positive wire and before starting implementation of the procedure wait not less than 10 minutes.
3. Remove the air cleaner with an inlet air duct (see the Head of the Power supply system and release). Remove a coal adsorber with the basic arm (see the Head of the Control system of the engine).
4. Give fixing nuts and remove a protective cover of the cardan hinge from a partition of a motive compartment. Mark position of the cardan hinge of rather entrance shaft of rack transfer, then turn out a coupling bolt of fastening of the lower intermediate shaft.

 Do not allow turning of a steering wheel by the removed rack transfer on the models equipped with safety cushions. In case of need remove a steering wheel and execute centering of spring contact (see the Section Removal and installation of a steering wheel). For a guarantee record a steering wheel not movably by means of a seat belt.

5. Get drain capacity under a case of rack transfer. Disconnect pressure head and returnable hydraulic lines from a case of the steering mechanism. At once to a zakuporta the open ends of lines in order to avoid hit in system of dirt and for the purpose of minimization of losses of hydraulic liquid.

6. Weaken wheel nuts, a front of the car and establish to a poddomkratta it on props. Cock the parking brake and remove wheels. At the corresponding complete set of the car remove protection of a case.
7. Release tips of steering drafts from levers of rotary fists (see the Section Removal and installation of tips of steering drafts).
8. Remove a bar of the stabilizer of cross stability (see the Section Removal and installation of the forward stabilizer of cross stability).
9. Remove the central cross beam passing under the power unit (see the Head Dvigatel).
10. Give nuts of bolts of fastening of the steering mechanism. Separate an intermediate shaft of a steering column from an entrance shaft of rack transfer. Take assembly of the steering mechanism from under the car.

11. Check a condition of landing plugs of support of assembly of rack transfer. In case of identification of signs of destruction of rubber replace plugs.

DISMANTLING

 PERFORMANCE ORDER

1. The design of a rack preedacha is presented on an illustration.

2. Before starting dismantling of rack transfer measure effort of tightening of a gear wheel and write down result of measurement as the recommended value. Before measurement disconnect the hydraulic line and merge working liquid from a case. Do not clamp the case made of aluminum alloy in a vice.

3. Take a gear wheel, - try not to damage sealing rings.
4. Release a bandage and remove a protective cover.

5. Disconnect a bar of steering draft from a lath.

6. Release a clamp and take assembly of the leading gear wheel.

7. Drill fastening at an end face of a case of the steering mechanism (use a drill on 2 mm).

8. Remove a face cover of a case of rack transfer.

9. Take a steering rack and remove from it a sealing ring, - use the hair dryer, having warmed up a ring up to the temperature about 40 °C.

10. Remove the central plug and sealing laying of a steering rack, - try not to damage the internal surface of the case of a gear wheel.

ASSEMBLY

 PERFORMANCE ORDER

1. Before installation on a lath warm a new teflon sealing ring the hair dryer up to the temperature of 40 °C. For landing of a ring use the special tool.

2. Establish a sealing cuff of a lath. To prevent risk of damage of a cuff about teeths of a lath pass in it the polymeric film twisted in a tube.

3. After installation of a cuff take from under it a polymeric film. Make sure of correctness of landing of a cuff. Put the central plug and a cuff.
