feed to the distributor coincides with
the connecting line of the
distributor centre
line ond the first cylinder
heod
bolt os
per
Fig.2.3l10. Secure the distributor in this pos-
ition by lightly tightenning the tie-bolt ond
remove the timing geor
cover from the cylinder
block. The used type of distributor is described
in Chopter 13.5.

surfoces of the
timing geor cover ond the cylinder
block, locote
the cover gosket
on the block,
oil the timing
choin ond the comshott worm geor.
Remove the
f lywheel powl
ond rotote the
cronkshoft through
360o so
os to bring tlre pistons
of the cylinders
No. 1 ond 4 to their TDC position
ogoin. This
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
the position
of the orm by
slightly
rototing the distributor.
lf the
misolignment of the distributor
ornr
ond the timinq
mork of the
cvlinder
No'1 is so greot
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
suction stroiner tothe cronkshoft centre beoring
ond use o spring
wosher under the bolt heod.
27. Bolt down the timing geor
cover using
spring woshers ond
cheese-heod bolts
(exclus-
ively) cnd f inolly fosten the timing geor
cover
in such o position
thot the contoct breoker
points open before the crronkshoft with
the con-
necting rod ond piston
hos ottoined the top
deod centre (TDC)
position (see
the lgnition
Timing Toble in Chopter 15.3).
For checking the ignition odvonce, on electric
power supply is required with o bulb connected
in o circuit with the distributor. this
circuit
being interrupted by the oction of the contoct
breoker. An odopted conventionol torch with o
metol
iocket con be
used with odvontoge for this
purpose. Remove the flywheel powl ond
set the re-
quired ignition odvonce by turning the cronk-
shoft with o screw'driver inserted into
the geor
ring ond propped ogoinst the cylinder block
f longe. Rotote the shof t onticlockwise o bit
more thon necessory ond
bock it off so os to
odiust the bocklosh of the timing geors
ond the
distributor drive geors.

heodlomps is the
so-colled support plote
(rec-
tongulor plote)
ottoched to the bodywork by
copscrews with lock woshers. The
heodlomp
housing is bolted to this suPPort plote by bolts
with nuts ond lock woshers. One of the bolts holds
down olso the
lug of the eorthing coble-
The inner frome,
forming the
odiusting element
of the heodlomp insert, is ottoched
to the
hous'
ing by two speciol odiusting screws
ond two
tension springs. The heodlomp insert
is ot'
toched to
the bezel by
three copscrews.
There is one left-hond ond
one right-hond
support plote.
Both should
be mounted with the
oriow ond the word "TOP"
upwords. With
the
exception of the ouxiliory heodlomps, the
heod'
lomp inserts ore different for
the left-hond ond
the right-hond troffic. The leods
enter the hous-
ing through o
rubber grommet.
When r-eplocing the insert, remove
the bezel
copscrews. After
hoving fitted o new insert, it
is necessory to reodiust the
heodlomps.
