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

ofter its
connection to the electric
power supply, tighten (screw
down) the screw
till it begins to be litfed by the geor
com ond
till the wiper begins to be

WIPER ARM DRIVE
This drive consists of thewiper beoringswith
cronks, the tie-rod of the
cronks, ond
the driv-
ing tie-rod. The
drive is instolled in the cor os
o unit.
Tie-rods The tie-rods should be slipepd on
the cronk
pins in the
following sequence:
o springwosher
with its centre comber focing outword (owoy
from the pin),
o flot
wosher, the tie-rod, o flot
wosher, ond o lock
ring.
lf necessory, lubricote the ioints with
greose
- see the following section deoling with beor-
ings. Fill the cover at the point
of the tie-rod
motor cronk connection with greose
(of ony
brond) ond slip it on the tie-rod.
Beorings On one side, the beoring
is inserted into the
wiper brocket from inside the body, on the
other side, it is fitted into o speciol wosher in-
serted with its nose foremost
into the re-
spective hole in the body. Locote o seoling
wosher with corefully smoothed-out edges ond
o flot
wosher from outside, ond secure the
entire unit with the respective
nut. The
unit is
seoled off by
o rubber pocking.
Fill the unit
with greose (see
Chopter 15.3 for recommended
foreign bronds or Czechoslovok Lrronds SP 4 or
A 4) ond press
it down into the neck of the
bush.
lf it is necessory to remove
or disossemble
the beoring, prise
the lock ring out of the pin
groove under the rubber pocking.
On reossembly,
insert o spring wosher under
the bush with its
combered centre
toword the bush. Lubricote
with the specified greose.
Wiper Arms
The wiper orms fitted with o rubber
blode
con be swung owoy from
the windscreen. They
ore held down by nuts
on the grooved
topers of
the beoring pins.
After hoving fitted
the wiper orms, sproy
woter on the windscreen
ond test the run
of the
wipers. lf necessory, turn the wiper cms
on the pins.
The wipers must wipe
the lorgest
possible oreo of the windscreen without, how'
ever, touching the windscreen glozing
mould-
