Attention! When carrying out work, observe absolute cleanliness. Avoid clogging the system. Disconnected pipelines and places of their installations should be plugged with caps/plugs.
The replacement of the power steering mechanism must be carried out in the following order. Prepare fixture «32.3.090», using a clean syringe, draw out the liquid from the reservoir (tank) hydraulic booster and dispose of it.
Remove the front wheel, remove the crankcase protection panel and, if necessary, the screen of the auxiliary mechanisms of the engine compartment. Remove stiffening plate. Loosen the nut on the engine support bracket on the left and right.
Raise the engine with the tool «00.0.200» (see section «Engine»). Set the steering gear to the position for driving in a straight line, while the marking on the cap (1, see fig. 12.8) and on the hull (2) must match. In this position, remove the key from the ignition and lock the steering wheel.
Loosen the bottom clamp bolt (M8) double cardan (arrow, fig. 12.17). Unscrew the bolts M12x1.5x75 (arrows, see fig. 12.15) fastening the steering mechanism to the beam of the front axle. Remove the dual cardan shaft from the steering shaft.
Loosen the nuts securing the tie rod ends (right and left) to the pivots. Using a puller (fixture «32.3.090»), press out the right and left tie rods (arrow, fig. 12.18).
Support the front axle beam with a garage jack, unscrew the bolts (arrows, fig. 12.19) and lower the jack. Remove the heat shield, unscrew the hollow bolts (arrows, fig. 12.20) and remove the steering gear by moving it to the left side.
The installation of the steering mechanism should be carried out in the reverse order, if necessary.
Replace O-rings (D, 4 pcs.) hollow bolts (M14) and tighten the bolts to 33 Nm (3.5 kgf·m), and hollow bolts (M16) – torque 39 Nm (3.9 kgf·m).
New bolts (M12, 10.9) fasten the front axle to the longitudinal member to tighten to 100.0 Nm (10.0 kgf·m).
Tighten new self-locking tie-rod end nuts to 80 Nm (8.0 kgf·m), at the same time, there should be no traces of grease on the landing cone of the tip and in the hole. If necessary, hold the assembly from turning by the internal hexagon.
Check the alignment of the marks on the steering shaft and steering shaft (see fig. 12.8).
Tighten bolt (M8) steel double cardan with a torque of 24 Nm (2.4 kgf·m) or torque 28 Nm (2.8 kgf·m) - when it is made of aluminum alloy.
Check the distance between the front side member and the dual cardan shaft.
Replace self-locking nuts (M12, 10.9) fastening of the steering gear and tighten them in three stages - a torque of 100 Nm (10.0 kgf·m) + 50 Nm (5.0 kgf·m) + Tighten by 90°.
Fill the reservoir with fluid, bleed the power steering and restore the fluid level.
Check and adjust the angles of the front wheels. For what, loosen the locknut (1, see fig. 12.14) tie rod on the left and right side. Carry out the adjustment of the toe-in by turning the tie rod on the hexagon (2).
Install stiffening plate (see fig. 3.57) and tighten the bolts of its fastening in two steps: tighten with a torque of 56 Nm (5.6 kgf·m) + Tighten by 90°.
