thot they do
not obstruct the movement of the brushes ond
so thot they connot
couse o short-circuit.
3. Top the stotor lightly with o soft
mollet
to settle it in
the beorings, ond lubricote
the
beorings. 4. Connect the motor to the power
supply
ond test briefly its running ond direction
of
rototion. lf it rototes in the opposite direction,
rotote the frome

When it is roining or when woshing the cor,

pressure in the cor interior ond to prevent
the woter from sooking the interior trims ond
running down into the cor. Therefore,
it hos
to be stuck on by rubber cement os shown
in Figs. 14.512 ond 14.5/3 (cross hotching).
First slip the lower port

Close both doors
on the side to be adjusted
and visually assess which areas of each door
require re-positioning to produce
an even
contour joining
the front and rear
wing body
lines in relation to the door
heights.
With careful adjustment of hinges, satisfactory
body lines
can be obtained.
Hinges can
be moved on the door pillar in
the
following ways.
1 . Up and down after slackening bolts.
Result:

2. In and out after slackening bolts. Result:
Position of
the door leading edge in
relation to bodY aPerture'

a) Shims under
both hrnges moves
the door
rearwards and
increases the gap
between
the door leading
edge and the
wing
(Front door).
b) Shims under the bottom hinge
only, will
lift the lower edge
of the door.
c) Shims under the top
hinge only, will
have the reverse effect.
It is
sometimes preferable to remove
the door
catch (On pillar)
to remove misleading stresses
being placed
on the door. This part
being re-
fitted and adjusted so
that both stages of
the lock are
working and
ensuring door is not
being stressed by
excessive tension
up or
down, in or out.
Adjust the door
catch to ensure when
the door
is closed, it will
not ride up or down'
Ensure the door does not catch the door pillar,
wing, other door etc., when both are open or
closed.
Door top half
lf you-have correctly
adjusted the
bottom half
of thb door you
may find that the window frame
top half still needs an adjustment.
Here it will be necessary to
lower the moving
window and carefully bend the
frame of the
window to match the frame

The position
of the door cotch retoiner on

ond/or the reor wing foce con
be odiusted within certoin limits ofter loosen-
ing its fostening screws. Adiust the retoiner
in the required position,
check the door for cor-
rect closing ond fitting
with the other ports
of
the bodywork, ond then retighten
the screws.
The door cotch must slide
on to the leodlng
surfoce of the retoiner
so thot it rests
ogoinst
it. Sometimes, it moy be necessory to ploce
o pocking piece
under the retoiner (to
prevent
the fouling of the door cotch pin).
ln such
o cose, mork the position
of the
cotch on the
bodywork, slocken the screws, ond instoll o
pocking piece under the retoiner slipping it
over the lower screws ond
tipping it into po-
sition on the upper screws. It is importont to observe the correct ongle
of the inclinotion of the retoiner leoding sur-
foce, which hos to
correspond with the incli.
notion of the beoring surfoce of the door cotch
(outer door lock). Therefore, fosten the bose
plote of the retoiner so thot its upright stiffener
is porollel
with the edge of the moulded recess
for the retoiner
on the door pillor
ond the reor
wing. The leoding surfoce of the retoiner is provided
with o friction plote.
In the cose of domoge
(excessive weor, impoct of on incorrectly od-
iusted door, etc.),
prise
off the originol friction
plote ond fit o new one. lf the friction plote is
locking or if it is excessively worn, the door is
opt to rottle.

When using this method, the volues of the

is indicoted by the
diognostic equipment itself.
To Adiust ldling Speed
Use the oir-correction screw (speed
cor-

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

before
storting the odjusting procedure (see

Brqke Fluid Chonge
The broke f luid obsorbs otmospheric humidity
ond the chcnge of its properties
is opt to offect
broking ond even bring obout corrosion of some
ports of the broke system.
The time period,
in which these chonges
con
toke ploce,

cision. Therefore forestoll troubles ond chonge
the broke fluid in the broke ond clutch system
every few yeors (preferobley
two to three
yeors ) .
Suck out the old f
luid from
the tonk, fill in
fresh fluid, ond remove the bleeding screws
one
ofter onother to let the old fluid be forced out
by the fresh
one from oll bronches of the broke
line to the clutch -
see the broke ond clutch
bleeding procedure.
Broke Bleeding Air con get

or dis-
montling some ports
of the hydroulic line. lf
