1.6 STARTING THE
ENGINE AND CHECKING
ITS CORRECT RUNNING
1. Moke sure thot the geor
lever is in its
neutrol position,
switch on the ignition (pos-
ition I on the switch box) ond wotch the
coming on of the oil pressure ond chorging
worning lights, i.
e. check the function of the
olternotor -
see the informotion in porogroph

Prepore the engine
to its temperoture:
- Storting from cold in
the occelerotor pedol
- Storting from cold in

choke for
storting occording
winter -
do not touch
ond use the full choke
summer -
do not touch
ond use only holf of the

Wheel Lock
crnrl Safety Lotch -
Storting o wormed-up engine -
depress the
occelerotor pedol
slowly to tlre
toe-boord, do
not touch the choke
2. Depress the clutch pedol
(odvisoble
in
summer, necessory in
winter) ond stort
the
engine by turning the ignition key to position
ll.
Let go
of the key os soon os the engine fires
ond releose the occelerotor pedol
{if it hos
been
clepressed).
It the engine ,refuses
to fire, return the key
to the position "0"
ond rePeot the
storting
Pro-
cedure. lf the engine is wormed up, depress the
occelerotor pedol
to obout one third of its totol
trovel. lf the cold engine stolls even
ofter the
second ond third storting ottemPt, enrich the
storting mixture by quickly
depressing the
oc-
celerotor pedol
once or twice to holf of its
trovel during the next storting ottemPt.
Never let tlre storter motor run for more
thon
obout 5 seconds. Woit
some 5 seconds before
repeoting the storting.
Fuel is injected
by every quick
depression of
the occelerotor pedol
ond enriches the mixture
so thot it is difficult to ignite. lf the engine
is flooded, stort
it
with o fully depressed oc-
celerotor pedol.
3. Increose the engine speed corefully while
releosing the clutch pedol. lf the
engine shows
signs of stolling, depress
ogoin the clutch
pedol.

position corresponds opproximotely
to the volve
geor position
when the cylinder No. 1 f ires (the
tips of the coms of
cylinder No. 1 ore turned
downword, owoy from
the engine). Lock the
cronkshoft in position by refitting ond tight-
ening the flywheel powl.
25. Turn
the distributor orm in the direction
of the
screw (1) in occordonce with Fig. 2.3110,
hold it down with the
finger in this position,
ond ref it the timing geor
cover on the cylinder
block. By sliding the worm geor
of the distribu-
tor drive into the comshoft worm geor,
the orm
is turned to coincide with the timing
mork for
cylinder No. 1
on the distributor housing. lf
there is no coincidence of the orm ond timing
mork, od just

of the orm by
slightly
rototing the distributor.
lf the
misolignment of the distributor
ornr
ond the timinq
mork of the
cvlinder

thot it connot be corrected
by rototing
the distributor, remove
the timing geor
cover,
rotote the distributor slightly ond repeot
the
entire procedure
of refitting the timing geor
cover. 26. Smeor the protruding
end of the cronk-
shoft ond the outer shoft end (stem)
of the
belt
pulley with oil, f
it the belt pulley,
the nespective
wosher, ond tighten the bolt. Bolt the
PumP

ond use o spring
wosher under the bolt heod.
27. Bolt down the timing geor
cover using
spring woshers ond
cheese-heod bolts
(exclus-

used with odvontoge for this
purpose. Remove the flywheel powl ond
set the re-
quired ignition odvonce by turning the cronk-

the longer, cylindricol port
foces the clutch,
push it ogoinst the friction plote
hub, ond olign
the ends of the levers to touch the flonge.
A deviotion from the ploneness
of 0.1 mm
is
permissible. Use feeler gouges for checking
this deviotion.
lf it is not possible
to odiust the out-trovel of
the clutch releose levers to o volue given
by the

the next higher volue.
Clinch nuts on the
odiusting nuts bocked off up to the end of the
threod ore o worning of o weor limit which pre-
cludes ony further odiustment
of the clutch.
4. After hoving reossembled
the engine with
o new or odiusted clutch,
check ond, if necess-
ory, odiust the cleoronce between the releose
levers ond the throw-out beoring -
see Chop-
ter 15.4.
3.3 CLUTCH DISMANTLING
Owing to its simplicity,
it is not necessory
to
describe in detoil the dismontling
of the clutch,
but some speciol feotures
deserve ottention.
1. lf the friction plote
ond clutch cover ore
intended to be re-used, mork their relotive
positions using centre punch
morks to preserve
the originol bolonce of the ossembly.
2. To dismontle
the clutch, it is
necessory to
compress the clutch cover to relieve the stress
of the releose lever bolts. For this purpose
use
the MP 2-101
ossembly plote
shown in Fig.3.4/1.
After screwing off the releose lever nuts ond
compressing the clutch cover,
the clutch is
reody for dismontling.
3.4 CLUTCH REASSEMBLY
1. Locote
the clutch pressure
plote
on the
MP 2-101
ossembly plote
ond fit springs
on the
cylindricol bosses. Before fitting
the springs, it
is odvisoble to check them for
complionce with
the volues specified
in the following Toble.

Instoll retoining plotes

lever springs in position.
Assemble the clutch
cover with the pressure plote,
observing the
morks indicoting their relotive positions.
When
ossembling new pot'ts,
their positions
ore of no
consequence.
3. Slip o 4.5 mm high pod
over the ossembly
plote bolts (the
plote
con be used
for Skodo
1000 MB ond Skodo 100 cors os well,
ond by
using pods
of different heights, the plote
con be
odopted for different
types of clutches), fit the
yoke of the
iig on
the plote
bolt ond compress
it by screwing down the nut till the bottom port
rests on the pod.
When compressing the clutch
cover toke core thot the projections
of the
pressure plote
ore correctly centered in
the
cover slots to prevent
o distortion of the clutch
cover.
4. Slip the bottom ends of the releose levers
under the springs instolled in the cover ond fit
them with their longitudinol
slots on the sup-
ports. Slip odiusting woshers on the bolts of the
pressure plote ond screw down the nuts with
their cylindricol port
focing the woshers. Then
odjust the height of the releose levers with
these nuts so thot their ends touch the shoulder
of the yoke
bottom port.
The difference of the
lever height should not exceed 0.'l mm. This
odiustment olso sets the recommended
distonce
of the levers from the pressure
plote
beoring
surfoce.
Use clinch nuts for locking the odiusting nuts
in position,
put
supporting clips under the re-
leose f ever ends os shown in Fig.3.111 ond3.212,
ond slocken the nuts of the ossembly plote.
The
clips ore useful when fitting the clutch to the
f lywheel since it is not necessory to overcome
the tension of the clutch springs.

Note: The 3 mm shim should
be used only
when replocing the wheel hub or when elimirr-
oting on oscertoined shoft ploy,
thot is
to soy
if the shoft moves oxiolly ond
knocks. However,
it is recommended never
to use more shims
thon three.
5. A domoged seoling
ring con be removed
with o hook or o needle, ond o new one driven
or pressed-on.
The lotter olternotive should be
preferred with regord to the visuol checking of

shoft,
smeor it with oil, ond move the seoling
ring
olong it to drive it finolly into the holf-oxle
using tlre MP 5-116 drift os shown in Fig-
5-212.
For pressing-on
the seoling ring, use the MP
5-112 iig (see

Gouge 5.6 HALF.AXLE DUST BOOTS
To prevent
oil from leoking through the
ioint
gop between the dust boot ond the joint
guord
os well os ony twisting of the boot during
the oction of the rood spring, or its domoge by
contoct with other cor ports,
it is importont to
observe its correct position
on the holf-oxle. lt
should be locoted
with its
flonges focing
reor-
wqrd ond tilted upword ot on ongle of obout
45o. For better occess, ploce
the clips fostening
the dust boot to the holf-oxle ond cover with
their screws on top. With the right-hond
boot,
screw in the clip screws from the front,
with
the left-hond boot the screw on the holf-oxle
from the reor ond on the cover from the front.
Connect the dust boot flonges with hollow
rivets using suitoble pliers.
lf riveting pliers
ore
not ovoiloble, bolt the flonges togethen instol-
ling odequotely dimensioned ploin
woshers
under the bolt heods ond nuts.
5.7 HALF.AXLE SHAFT
The thrust ring of the beoring (behind
the
shoft toper) is pressed
on the shoft. lf it is ne-
cessory to renew this ring, for exomple ofter
repeoted replocements
of the beoring (see
Chopter 5.1, porogrroph

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

You will find the respective volues
in Chopter
