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.

cooler into the cor,
proceed in occordonce with the circumstonces
of the removol. Secure the bolts conecting the
oil cooler with the engine guord
ond the brocket
(the brocket being locoted between the cooler
ond the guord)
with spring
woshers. Bolt down
the guord
over ploin
woshers ond use o spring
wosher for the bolted connection of the brocket
with the bodywork.
Use seoling
woshers when connecting hoses
to the engine ond the oil cooler, ond put
o seoling wosher olso under the bolt. Close the
bolt of the engine port
ot the flonge with the
pressure switch. Fosten the hoses so thot they
ore not stressed in their bends. The
hose from
the timing geor
cover should be routed horizon-
tolly ond the hose ot
the engine inlet so thot
it includes o downword ongle of obout 15 de-
grees with the horizontol plone. Top up
oil in
the engine.
11.10 COOLING SYSTEM DEFECTS,
TESTING, REPAIRS, AND
CLEANING
Defects ond Testing o) lf there is o marked loss of coolont, check
oll connections for leokoge. The
loss of coolont
con olso be coused by o leokoge of the rodiotor
(or heoter). lf the leokoge point
is not visible,
pressure-test the system without removing it
from the cor. Admit seoled-off oir ot o pressure
of 0.12 MPo
(1.2 kglcmz) into the filler neck ond look for
ploces where the coolont is seeping or dripping
out. Inspect not only the rodiotor but olso the
lreoter. An excessive loss of the coolont con be olso
coused by engine overheoting. In thot cose,
look for the couse of engine overheoting.
b) Points to check if the engine
is overheoting
- coolont level
- operotion of thermostots ond rodiotor fon
- condition of rodiotor (whether
clogged out-
side with dirt, or whether cooted inside with
scole)
c) Points to check if the engine does not worm
up properly:
- operotion of thermostots
