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.

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

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

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.

Length of spring in mm
lin -rrr"ltp1
Mounted length
31.55'10+36

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.

The moin pipeline
routed under the cor f loor
consists of front ond reor pipes.
They ore em-
bedded in o chonnel moulded in the floor
boords ond rest on on insuloting (polysterene)
podding. From below, they ore protected
by
o guord,
the copscrews of which ore locked
in
position by spring woshers.
Use pipe
holders (yokes) to fosten the pipe-
line to the floor. In
the front

Use spring woshers under
the
heods of copscrews.
Before instolling the pipes, prepore
ouxiliory
yokes (or use lengths of wires ottoched to the
provisionolly screwed-in copscrews of the pipe-
line guord) to liold the pipes
in the moulded
chonnel in
the floor before
the finol fostening
of their guord.
The woter line runs
under the cor together
with other lines, pull-rods,
etc. For their mutuol

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

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)
