Ihe permissible
out-of-bolonce must not ex-
ceed 50 grommes
on the rim rodius. Every new
tyre is provided
with o coloured dot on its side,
indicoting its lightest point.
Fit the tyre olwoys
with this dot focing
the tube volve.
ln this
position, the volve octs os on odditionol weight
compensoting the wheel overoll unbolonce to
o consideroble extent.
lf dynomic boloncing of the wheel is not
possible, bolonce the wheel stoticolly with the
greotest possible qssuroc|.
Boloncing weights
of 30, 50, 75,
ond 100 grommes
ore ovoiloble.
10.4 TUBED TYRES
For mounting,
dismounting,
ond repoirs of
conventionol tyres with inner tubes (for
por-
ticulors, see the preceding
Chopters), the usuol
procedures ore opplicoble. The permissible run-
out (untrue
running)
of the rim is the some os
for tubeless tyres (Chopter
10.5).
10.5 TUBELESS TYRES
The oir-tight seoling of these tyres requires
more core ond o different hondling thon thot of
the tyres with inner
tubes.
Preporotlon of Rirrr
13elore mounting the tyre, inspect the rim for
ony technicol defects. The points
to be checked
ore the rim shoulder ond the moting foce for
the tyre beods,
in oddition to the overoll con-
dition of the rim. lf ony defects ore found, the
rim must be reconditioned.
A sotisfoctory rim
nrust comply with the following conditions:
o) The
rim shoulder ond the tyre volve hole
must not be distorted;
there must be no
shcrp edges or protrusions
likely to domoge
the tyre beod. Minor unevennesses
con be
hornmered flot ond smoothed
with o file.
The moximum eccentric running
of the rim
side must not exceed 1.5 mm.
b) The moting surfoces
must be obsolutely
cleon (free
from stuck-on rubber, rust,
etc.).
Cleon them with emery poper
or o wire brush
ond coot them with point.
lnstolling of Tyre
Volve
Cleon the rim with o dry rog. Push
the rubber
volve into
the hole in the rim
or pull
it in
by
its threod using, for exomple,
o lever
os illus-
troted in Fig. 10.5/1. Fig. 10.5/1

Pulling Tyre Volve
irrto Wheel Rim
Mounting the Tyre
For mounting the tyre, use speciol mochines
ond procedures,
depending on the type of the
nrochine. lf such o mochine is not ovoiloble, in-
stoll the tyre using speciol tyre levers.
Ensure
thot the boloncing dot is next to the volve.
Tyre leverrs for fitting tubeless tyres
differ in
shope from conventionol levers. They
ore thin-
ner, without edges, ond polished.
Use them core-
fully in order not to domoge the
beod seoling
rubber bose. Insert the levers
under the beod
ot
short distonces ond refroin from using force. To
focilitote sliding of the tyre cosing beods over
the rim shoulder, moisten them with woter ond
top them with o rubber
mollet when eosing
them over the rim shoulder. Inflote
the mounted
tyre immediotely. Check the tyre for propei'
bedding in the rim ond
squore seoting
on it.
Holding the wheel perpendiculorly,
strike it
severol times ogoinst the f loor ot severol points
to force the tyre beods
to bed
correctly on the
bcad seots.
lnf lotion
Remove the volve
core to increose
the diom-
eter of the hole for oir inlet (oir
should be
iniected in quick
shots to force
the beods
on
to the beod seots) ond inflote the tyre. Use
o compressor with oir receiver, the
compressed-
.oir line of the
workshop, or
compressed-oirr
cylinders. The relief volves hove to be odiusted
to o pressure
of 350 kPo (3.5
kg/cmz).
Never ollow the inflotion pressure
to rise
unnecessorily. As soon os the tyre hos snopped
into position
on the rim
ond is free from leoks,
odiust the pressure
to 250 -
350 kPo (2.5 -
3.5
kg/cmz). lf the tyre refuses to
bed properly
on
the rim,
for exomple due to distorted beods or
beods compressed due to incorrect storoge,
press the tyre circumference inword to open
wide the beods which will then bed properly
on the rim. Use either o length of
rope or
o speciol tightener. Slip the rope over the
tyre
circumference with o certoin cleoronce, insert
o stick
between the tyre ond the rope, ond
twist the rope.
Adiust the tyre pressure
to specif
icotions ond
submerge the wheel in woter to check the
tyre
for oir leoks.

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.

a water leak
proceed in a progressive
manner.
1. Determine area
water finally rests'
2. lf possible follow
water trace to
source'
3. lf hot, remove carpets and clutter'
4. Dry car inside
and out'
5. Us'e a sprinkler rather
than
a hose jet'
6. Start on the
underside of
the vehicle and
work up. Do not
do any adjustments or
sealing until after the
first test.
7. When"you have
finished adjustments and
sealing RE
TEST.

Mobiloil 30 is on oil in the SAE 30 viscosity
closs, Mobiloil Speciol belongs to the SAE
10 W/30 closs. We quote
the viscosity closs
symbol of oils identified
in this woy in brockets
following the oil brond (trode

Oils designoted by o doubled viscosity closs
symbol ore the so-colled multigrode oils. Their
complionce with viscosity clossificotion is ex-
pressed by the symbol before the froction line
progressively to the clossificotion expressed by
the symbol behind the froction line. Thus,
for

cision. Therefore forestoll troubles ond chonge
the broke fluid in the broke ond clutch system
every few yeors (preferobley

with
high-quolity greoses which
do not
dry, do not
oxldize, ond protect
the mechonisms ogoinst
corrosion for o long time. Oil is
not suitoble due
to its short-time efJect. Any greose con
be used
to lubricqte the
