When inspecting the steering knuckles of the front axle,
check to be sure that the adjusting bolts 27, the steering stop 28
are in serviceable condition and are reliably locked with the nut.
The front driving axle is provided with a device for
disengagement of the front wheels (Fig. 49 III, 50 III).
For disengaging the front wheels, remove hub cap 18, 16
(Fig. 49, 50) and by screwing out bolt 16, 17 set coupling in
position in which a circular indicating groove "a" on the surface
of coupling is arranged in one plane with the face of flange
14, 13 (Fig. 49, 50, view III). Having set coupling in a required
position, screw on hub cap.
For engaging the wheels, screw in bolt 16, 17 as far as it will
go. Be sure to engage and disengage both front wheels.
Some automobiles could be equipped with a sleeve for
disengagement of the front wheels, shown in Fig. 49 IV, 50 IV.
For disengaging the wheels, turn the disk of the sleeve counter-
clockwise as far as it will go arranging in one plane the mark "á"
with the figures "4õ2". For engaging the wheels, turn the disk of
the sleeve clockwise as far as it will go arranging in one plane
the mark with the figures "4õ4".
Never engage the front axle when the front wheels are
disengaged.

Towing Hook
The towing hook is intended for towing a trailer or an
automobile by means of flexible coupling, and also it allows a
short-time operation by means of rigid coupling. Towing of a
trailer on a broken ground is not allowed.
The hook is provided with a catch 3 (Fig. 51) which closes
the mouth of hook and is locked in the closed position by means
of the pawl under the action of the spring.
The pawl in the catch is closed by a cotter 4 to avoid
spontaneous uncoupling.
Maintenance of the towing hook comes to periodically
cleaning of dirt, checking it for reliable attachment to the rear
cross-member and lubricating according to the directions of
Lubrication Table.
