with o geor
cosing, o lever system
driving the wiper orms, ond two wiper orms
with wiper blodes.
The two-pole wiper motor
with permonent
mognets is o two-speed
unit with self'lubri'
coting beorings. The geor
cosing comprises onepicyclic
geor
ond on outomotic self-porking
device. The shoft runs in self'lubricoting beor'
ings, the geors
being lubricoted with greose
pocked into the geor
cosing. The lever system
(leveroge) includes self-lubricoting
ioints ond
beorings.

Refitting
According to the
noture of the required re-
poir, remove either only the motor with the geor
cosing after hoving disconnected the pullrod
from the cronk, the cronk from the geor
cosing,
ond the geor
cosing from the brocket, or remove
the complete unit
ofter removing the wiper orm
beorings -
see wiper orm drive.
When ref itting
the windscreen wiper unit,
observe the
ossembly position of the
wiper
cronk -
see the following porogroph "Motor
ond
Geor Cosing". For position
of the wiper
orms
(blodes), see the porogroph 'Wiper
Arms". ln-
stoll the brocket into the body bulkheod ond
fosten it in position
with the nut, using o rub-
ber ond o flot wosher.
Cleoning ond Repoirs
When disossembling the windscreen wiper
motor, do the following jobs:
1. Reploce worn brushes ond use petrol
to
cleon motor ports
ofter blowing the dust out of
the brushes; moke sure thot the brushes move
freely in their cells. 2. lf the commutotor is
dirty, cleon it
with
petrol, if it is domoged, re-turn ond polish
it.
3. During cleoning, the self-lubricoting beor-
ings must not come into contoct with the
cleoning (degreosing)
ogent (petrol,
etc.). They
should be lubricoted
only with o low-pour-point
oil dripped into the cut-outs of the
cup retoining the boll beoring ond
the felt. Use only os much
oil os the felt con hold.
4. For the epicyclic geor
in the geor
cosing
use greoses
specif ied in Chopter 15.3 -
either
of foreign
moke or of
Czechoslovok moke -
re-
commended specificolly
for windscreen wipers.
MOTOR AND GEAR CASING
Ports of the motor
with the geor
cosing (or
geored motor) is the wiper brocket,
the pro.
tective housing, ond the driving cronk. When
instolling the wiper, put
the housing
on the
motor with the geor
cosing ond clomp it from
below. Bolt down the brocket using ploin
woshers under the bolts. Fosten the motor
eorthing coble under one
of the bolts.
Fosten the cronk in position
using o nut
ond
o spring wosher while observing its ossembly
position:
o) with wipers for left-hond steering-toword
the right-hond side
of the motor ond deflected
13o downword from
the oxis porollel
with the
centre line
of the motor;
b) with wipers for right-hond steering
toword the left-hond side of the motor ond de-
f lected 17" downword from the oxis porollel
with
the centre line
of the motor.
Dismontling the Geor Cosing 1. Remove three screws ond lift owoy the
cover.

1. lf the wiper moves with the switch in the
OFF position
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
switched off ond

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-
i ng.

with
high-quolity greoses which
do not
dry, do not
