5.3.2. Removal, check and installation of a steering wheel and steering column
In the steering mechanism there is the rotary valve of control directing liquid from the pump of the hydraulic booster of a steering to one or other party of the piston of a gear lath of the steering mechanism. The piston and a gear lath make one integral part of the steering mechanism. The piston of a gear lath transforms pressure of liquid to linear force which moves a lath on the left or to the right.
This force is transferred through steering drafts and tips of steering drafts to rotary fists which turn forward wheels. At malfunction of the hydraulic booster driving is carried out in a usual mode. However thus it is necessary to make bigger effort. The rotary motion of a steering wheel is transferred to a gear wheel. At gear wheel rotation its teeths are hooked with lath teeths, thereby forcing a lath to move.
