Removing
To remove the steering mechanism, disconnect the wires from the battery and remove the signal switch by carefully prying out the three latches from the bottom through the window with a screwdriver. Loosen the steering wheel nut 10 (pic. 185) and remove it, then unscrew the screws, remove both halves 7 and 11 of the steering shaft cover.
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 crankcase to the body side member.
Remove the instrument panel and disconnect the three-lever switch connectors from the cable harness connectors. Disconnect the wires from the ignition switch terminals and, having unscrewed the mounting screws and drowned the lock latch, remove the ignition switch.
Loosen the clamp securing the turn signal switch housing, headlights and wiper and remove it.
Turn away a bolt of fastening of the lower end of an intermediate shaft 3 to a shaft of a worm of the steering mechanism. Turn away bolts and nuts 12 of fastening of an arm 6 and remove a shaft of a steering with an arm.
Unscrew the nuts securing the ball pins of the side and middle rods to the bipod and puller A.47035 (pic. 186) press the ball pins out of the bipod holes.
Remove the steering gear housing by first unscrewing the bolts of its fastening to the body side member. Loosen the seal fastening screws 2 (see fig. 185) and take it off.
Installation
Having fixed the seal 2 on the bulkhead, install the steering mechanism housing on the side member, without fully tightening the nuts of the crankcase fastening bolts. Use a special device to orient the crankcase so that the angle a (pic. 187) 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.
Set the bipod of the steering mechanism to the middle position, for which, align the marks No on the crankcase and on the worm shaft (see fig. 184). Temporarily install the steering wheel on the shaft so that the spokes are horizontal, and in this position, connect the intermediate shaft universal joint yoke with the worm shaft, then attach the steering shaft bracket to the body.
Remove the steering wheel and fit the turn signal, headlight and wiper switch onto the steering shaft.
Establish a steering wheel on a shaft in an initial position and, pressing a steering wheel, as it is shown in fig. 187, check that there is no radial movement of the shaft. For radial movement, 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. Attach the turn signal, headlight and wiper switch connectors to the wiring 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 middle and side left-hand ball pins on the bipod and secure them with nuts. Then adjust the toe-in 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 20 kgf (when measured on the wheel rim). With the steering wheel spokes horizontal, connect the worm shaft to the lower end of the intermediate steering shaft. After not fully tightening the steering shaft bracket bolts, turn the steering wheel several times in both directions, and then tighten the bracket bolts.
