Removing
Disconnect the wires from the battery and remove the signal switch by unscrewing the screws securing it.
Remove the steering wheel. Remove both halves of a facing casing of a shaft of a steering.
Note. If it is necessary to remove only the steering gear housing, unscrew the bolt securing the lower end of the intermediate steering shaft to the worm shaft and the bolts securing the housing to the body side member.
Remove the instrument panel and disconnect the plug blocks of the three-lever switch from the plug blocks of the wire bundle. Disconnect the wires from the ignition switch terminals and, having unscrewed the mounting screws and drowned the lock retainer, remove the ignition switch. Loosen the clamp securing the turn signal, headlight and wiper switch housing and remove it.
Unscrew the bolt securing the lower end of the intermediate shaft to the shaft of the worm of the steering mechanism. Unscrew the bolts securing the bracket 6 (pic. 5-3) and remove the steering shaft with bracket.
Pic. 5-3. Steering Details: 1 - steering gear housing; 2 - shaft seal; 3 - intermediate shaft; 4 - upper shaft; 5 - fixing plate of the front part of the bracket; 6 - bracket; 7 - upper part of the facing casing; 8 - bearing sleeve; 9 - needle bearing; 10 - steering wheel; 11 - lower part of the facing casing; 12 - fastening details of the steering shaft bracket
Unscrew the nuts securing the ball pins of the side and middle rods to the bipod, and then press the ball pins out of the holes in the bipod with a puller A.47035.
Remove the steering gear housing by first unscrewing the bolts of its fastening to the body side member. Loosen the screws securing the steering shaft seal and remove it.
Installation
Fixing spruce 2 on the bulkhead plate (pic. 5-3), install the steering housing on the side member, without fully tightening the nuts of the housing mounting bolts.
Use a special device to orient the crankcase so that the angle a (pic. 5-4) did not exceed 32°, and the gap between the shaft and the brake pedal was not less than 5 mm. Then fully tighten the crankcase bolt nuts.
Pic. 5-4. Installation of the steering mechanism on the car: 1 - bolts for fastening the crankcase of the steering mechanism; 2 - coupling bolt for fastening the lower end of the intermediate shaft; 3 - bracket mounting bolts; 4 - steering shaft bracket. 27.5 mm - distance from the center of the bipod hole to the bearing surface of the steering gear case with the bipod in the middle position
Set the bipod of the steering mechanism to the middle position, for which align the marks on the crankcase and on the worm shaft (see fig. 5-2).
Temporarily install the steering wheel on the shaft so that the spokes are horizontal and in this position connect the universal joint yoke of the intermediate steering shaft to the worm shaft, then attach the steering shaft bracket to the body without fully tightening the mounting bolts.
Remove a steering wheel and put on a steering shaft the switch of indexes of turn, light of headlights and screen wipers.
Establish a steering wheel on a shaft in an initial position and, pressing a steering wheel, as it is shown by arrows in fig. 5-4, check that there is no radial movement of the shaft. When moving radially, move bracket 4 slightly upward along the shaft axis until the radial clearance is selected. If this does not eliminate the radial clearance, replace the upper steering shaft or its bearings.
Check that the steering wheel rotates smoothly and freely in both directions, then tighten the steering wheel nut and tighten it at three points. Slide the turn signal, headlight and wiper switch housing towards the steering wheel until it stops, and tighten the switch mounting clamp.
Connect the wires to the ignition switch terminals and screw the switch to the steering shaft bracket.
Connect the turn signal, headlight, and wiper switch connectors to the vehicle harness connectors.
Mount the two halves of the cladding on the shaft and fasten them with screws. Install the horn switch on the steering wheel.
Install the ball pins of the middle and side left thrust on the bipod and secure them with nuts
Adjust the toe of the front wheels and check the force on the steering wheel, which, when turning the wheels in place on a smooth plate, should not exceed 196 N (20 kgf), 245 N* (25 kgf) * (when replacing on a wheel rim).
Note. You can separately assemble the steering shaft with the turn signal, headlight and wiper switch, steering wheel, and install this assembly on the car.
To mount the assembly, position the steering wheel spokes horizontally and connect the worm shaft to the lower end of the intermediate steering shaft.
Incompletely wrapping the bracket mounting bolts, turn the steering wheel several times in both directions, then tighten the bracket mounting bolts.
