The most importont points
from the point
of
view of driving ore the

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

Repair of Window Regulator Defects
lf the windows are difficult to wind up and
down (the
maximum torque applied on the
spindle of the window regulator with the glass
installed in the doors exceeds 2.5 Nm) (1.77
tt
lbs), it is recommended that the following steps
are taken as regards both the front
and rear doors:
1. Disconnect the regulator driving plate
from
the window glass
channel. Push the glass
upward
and try the relieved regulator by turning the
regulator crank. lf the regulator does not work
smoothly (jamming,
rattling) or if
a torque higher
than O.7 Nm/(O.495 ft lbs) in front and 1.1
Nm/(0.78 ft lbs) in the rear is required for its
operation, replace the whole regulator with a new
one working satisfactorily.
2. Adjust the centre pillar position
in the door
using the jig
as per
drawing No. A1-1 5417-S.
Loosen the top screw of the centre pillar
and
retighten it while pressing
the centre pillar
against the window glass
wound up to its upper-
most position.
Loosen the bottom screw of the
centre pillar
and retighten it while pressing
the
centre pillar
against the
window glass. 5417

3. When bolting together the regulator driving
plate with the window glass
channel make sure
that the holes in these two parts
coincide along
the whole length of the channel. lf it is not so,
move the
channel into a satisfactory position.
4. lf the regulator is
not lubricated, lubricate the
regulator cable in the
tubing with grease
and
apply oil to the regulator
crank spindle.

b) Stroboscopic method:
When using this method, the volues of the
bosic ignition timing ond
the odvonce con-
trolled by the centrifugol timing control (for
its
diogrom refer to Chopter 13.5) should be odded
upwhile multiplying bytwo
the odded upvolues
occording to the diogrom. Any effect of the
vocuum control must be
eliminoted by discorr-
necting the respective hose (connecting
the
distributor vocuum unit with the corburettor).
The meosuring procedure
is indicoted by the
diognostic equipment itself.
To Adiust ldling Speed
Use the oir-correction screw (speed
cor-
rection screw). The speed decreoses when ro-
toting the screw clockwise ond increoses when
rototing it onticlockwise.
Adiust the idling speed in occordonce with
the tochometer ond within the limits specified
in the following porogroph "To
Adiust ldle
Run". The engine must be wormed-up
before
storting the odjusting procedure (see
olso the
following porogrophs) ond its ignition must be
in perfect
condition (distributor
