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

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

Anchoring points
for rear seat belts are shown
in the illustation. For the seat
belt of the person
sitting in the
middle, the threads are under the
seat cushions and rather removed from each other
(A3). For the seat belts of persons
occupying the
butside places
the threads are also under the
cushions, nearer to the centre (A2),
in the body
sides close to the cusions (82),
and in window
pillars (C2). These latter threads can be found by
touch in the point
of intersection of the plane
passing about 165 mm
above the
rear window
parcel tray and in parallel
with the door frame at a
distance of about 85 mm. To gain
access to
them,
it is necessary to cut through the trimming.
We must stress that for the fitting of points A2
and A3, the bolts should not protrude

b) Stroboscopic method:
When using this method, the volues of the
bosic ignition timing ond
the odvonce con-
trolled by the centrifugol timing control (for
its
diogrom refer to Chopter 13.5) should be odded
upwhile multiplying bytwo
the odded upvolues
occording to the diogrom. Any effect of the
vocuum control must be
eliminoted by discorr-
necting the respective hose (connecting
the
distributor vocuum unit with the corburettor).
The meosuring procedure
is indicoted by the
diognostic equipment itself.
To Adiust ldling Speed
Use the oir-correction screw (speed
cor-
rection screw). The speed decreoses when ro-
toting the screw clockwise ond increoses when
rototing it onticlockwise.
Adiust the idling speed in occordonce with
the tochometer ond within the limits specified
in the following porogroph "To
Adiust ldle
Run". The engine must be wormed-up
before
storting the odjusting procedure (see
olso the
following porogrophs) ond its ignition must be
in perfect
condition (distributor
contoct-breoker
points, sporking plug
electrodes, ond ignition
odvonce).
