The thermometer indicotes the temperoture
of the coolont with the ignition switched on.
The optimum operoting temperoture ronge is
from 75 to 105oC. In
SfOon 105 S, this
ronge
is identified by
the green
zone of the scole.
The fuel gouge
indicotes the level
of the fuel
with the ignition switched on. The scole is
provided with divisions 0 -

The driver is worned by the red worning light

The tochometer indicotes the speed (revol-
utions) of the engine. The
speed should
never
rise to the red zone. When chonging the geors,
on increose of speed within the ronge
of the
yellow zone is permissible.
The porking

It is imperotive to set the
ongle with regord to
the direction of forword

by the orrow
Fig.6.1/5-Preporing front oxle for the condition
of check lood by inserting
steel bors of 181 mm
in diometer ond obout
220 mm long
The most importont points
from the point
of
view of driving ore the
toe-in ond the comber
ongle, the odiustment of which is permitted
by
the oxle design.
Adiust first the comber
ond then the toe-in
since o chonged comber
offects the toe-in.
We refroin from describing in detoil ony
meosuring method in view
of the lorge number
of existing gouges.
Insteod,
we odvise you
to refer to
the procedures recommended
by the
monufocturers of the gouges.
The check lood con be formed by blocking the
wishbones with bors occording to
Fig. 6.1/5.
Press down the cor with the hond, insert
the
bors under the wishbones so
thot they
beor
ogoinst the oxle brocket, ond releose the cor
to
let the bors be clomped. lf
clomping of the
bors
does not toke ploce
(which con hoppen on on
older cor with weokened springs),
consider the
condition os if the bors were
clomped, i. e',
corresponding to the position of the
front oxle
ot check looding.
The words "ot
full lood" describe o vehicle
looded so thot the distonce of the rubber deod
stop from the bottom of the
lower wishbone
stop is 20 mm (see olso porogroph
18) ond the
comber ongle of the reor wheels is 1". Meosure
these volues on oll wheels (not
only one front
ond one reor wheel) ond distribute the
lood os
necessory.
Toe-in To odiust the toe-in, screw
the right-hond ond
left-hond steering rods
symmetricolly (o
chonge
up to 1 mm con be effected by
one rod) ot
check lood so thot the distonce between the
wheel rims (or
ocross them) behind the oxle
(A+o) is lorger by the toe-in volue (o)
thon the
distonce between the rims
in front of the oxle
(A). To verify steering symmetry (correct screw-
ing of steering rods during
toe-in odiusting),
check the wheel lock position ot the
20" lock
ongle of the neorside wheel -
for the respective
volues refer to Chopter 1.7.
Slocken the steering rod
nuts ond rotote the
steering rods using on
olligotor wrench (Fig.
6.1/6). In oddition to the correct inflotion
pressure
of the tyres, poy
ottention to
severol essentiol
points when checking the wheel
olignment:
o) Ploce thewheel in the stroight oheod trovel'
ling direction;
b) The
steering rod ond the trock rod
must
not
be stressed. The stress con be eliminoted by
letting the cor swing
up ond down in its
suspension under the pressure of
your
honds
(olternotely press down ond releose
the
wings)
c) Prepore the oxle os
shown in Fig.6.1/5;
d) lf
o speciol gouge with
o scole for wheel
lock ongle setting is ovoiloble, odiust
the cor'
rect length of steering rods in
occordonce with
the position
of wheels in
check lock positions.
You will find the respective volues
in Chopter
1.7 "Steering".
Set the lock ongle
of the wheel
on one
side to 20' (on

both sides to relieve the front wheels, ond
remove the wheels. 3. Proceeding from
inside the luggoge boot,
remove covers protecting
the threods of the
shock-obsorber piston
rods ond screw off the
nuts. Retoin the piston
rod by holding its flot-
tened end.
b) Operotions inside the cor
4. Remove the steering wheel, the steering

from the body -
see Chopter 7.8.
c) Operotions from under the cor
5. Remove the bolt of the connection of the
steering shoftwith the steering box ond releose
the shoft sleeve from the connection by pull-
ing the steering geor
inside the cor.
6. Slocken the nuts of the bottom wishbone
pins fostening the front oxle to the brocket on
the body until the woshers of the brockets ore
releosed. 7. Detoch the onti-roll bor brockets from
the
body ond disconnect the rubber broke hoses
from the front broke systems.
Before discon-
necting the hose, cleon thoroughly the hose
connector ond its surroundings to prevent
foreign motter from getting
into the broke
system. For the some reoson,
wrop the
hose
ends in o cleon rog. Toke
the some precoutions
with the disconnected broke piping.
8. Ploce o roll-o-cor

lower the
iock, ond
move it with the oxle from
under the cor.
6.3 REFITTING FRONT AXLE IN
CAR
1. To reinstoll the oxle in
the cor, reverse the
procedure of its removol, i.
e., begin with the
porogroph 9 ond proceed
to the porogroph
1.
Coot the rubber
cup with greose
ot the point
of its contoct with the steering shoft.
2. While reconnecting the broke hoses, ob-
serve the utmost cleonliness ond bleed the front
wheel brokes if no other ports
of the broke
system hos been dismontled. (lf
such o dis-
montling hos token ploce,
bleed the brokes of
oll wheels ofter hoving fully reclosed

circuit). 3. Turn the wheels in the stroight oheod di-
rection before connecting the steering shoft
with the steering box. Fit the steering wheel tentotively
ond odiust the direction indicotor
switch -
see Chopter 13.17.
4. Using the steering wheel, tunn the wheels
into full lock positions
to moke sure thot the
lock ongle is correctly limited by the king pin
socket stops -
see Chopter 6.5, porogroph
36.
5. Adiust the toe-in -
see Chopter 6.1.
6.4 DISMANTLING
FRONT AXLE
No speciol instructions ore required for
dis-
montling mony of the subossemblies. Accord-
ingly, only the bosic dismontling procedure
will be
deolth with ond porticulors
will be men-
tioned only os fon

sequence of operotions ond the use of iigs.
Ports which con be dismontled witlrout re-
moving them from the cor ore the wheel hubs
and beorings, the broke mechonisms, steering
orms, shock obsorbers, ond the
onti-roll bor.
lf ony odditionol ports

remove the oxle from the cor ond dismontle it
on the stond.
Dismontling Wheel Hubs
ond Beorings
1. Dismontle the broke mechonism os per
