2.2O FUEL PUMP
Technicol DescriPtion
The model JIKOV MF 3407 fuel pump
is of
the diophrogm ond
lever type, controlled by the
round disc of the comshoft. The suction
motion
of the diophrogm is octuoted by the
lever, the
dischorge motion by the spring of
the dio-
phrogm. Fuel flows through o stroiner, o mud
trop, ond the suction volve to the delivery
volve. A priming lever is provided
for hond
priming of the fuel. The moving mechonism
is
lubricoted with oil
sploshed from the cylinder
block. Stroke of the driving disk 4
mm
Suction heod 1.5
mm
Deliveryheod. 2mm
Pump dischorge ot 2,000 strokes
per minute ond free outflowwithout
counter-pressure 30
ltrs/hr.

For routine
mointenonce (cleoning
of the
mud-trop screen) see Chopter 15.3. After hoving
operoted the hond-priming lever lift it
till it
engoges sofely in its locked position.
ln the cose of o defect, inspect the diophrogm
ond check the volves for leokoge. After hoving
removed the pump
from the engine, remove the
mud trop, seporote the upper port
from the
lower port,
ond remove two screws, holding
down the thrust plote,
to lift owoy the volves.
Swill oll ports

ond blow off with com'
pressed oir. Reploce domoged ports
with new
ones. lf necessory, remove the diophrogm from the
octuoting lever in
the lower port
of the fuel
pump (its
monufocturer recommends the dio-
phrogm to be reploced ofter obout 50,000 kilo-
rnetres with o new
one). Do not stretch the
spring of the diophrogm ond do not olter its
compression force chorocteristic in ony woy.
Do not forget to put
fibre pocking rings
underthe
volves
when reossembling the
fuel
PumP.
Put o spocer ring under the suction volve (close
to the mud trop). Fig.2.2Ol1 shows
the pos-
itions of volves ond the holding-down thrust
plote. Put the spring
of the diophrogm into
the
lower port
oi the pump
ond engoge the pin
ot
the diophrogm with the octuoting lever. Oper-
ote the hond lever

Turn
the flonge
on the centering
orbor so thot
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
length of the flonge cylindricol port
due to
excessive weor
of the friction plote, odiust to
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
on the clutch
springs ond fit the clutch cover with releose
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.

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

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

of the tyres, poy
ottention to
severol essentiol
points when checking the wheel
olignment:
o) Ploce thewheel in the stroight oheod trovel'

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

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.

CONNECTING LINE
The line is o
combinotion of steel pipes
ond
rubber hoses. All connections must be tightened
with clips of
the strip
type (see
Fig. 11.411) or
the wire type (bleed
hose). Toke
core not to
overtighten the clips of the lotter type os there
is o risk of domoging the rubber.
The hose from the pipe
of the thermostot
body on the engine is routed to the heoter
through the f loor tunnel, the return bronch
possing ogoin through the tunnel to the pipe
of
the pump.
Arronge the hoses olong the sides
of
the floor tunnel so
thot they do not touch other
ports in the tunnel.
For detoiled informotion obout the routing of
the hoses refer to
Chopter 12.7.

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

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
