3. To evoluote
the doto
obtoined from
the diol
indicotor reoding ond the
doto of the geor
set,
odopt the following procedure:
The setting distonce of the gouge -
60.00 mm
- is morked on the gouge
orm; the reoding
of
the diol indicotor
hos shown
o deviotion
of e. g.
plus 66 divisions, i. e. 0.66 millimetres (plus
meons thot the tip
of the gouge is pushed
in-
word from the set zero position
ond the in-
dicotor reoding is higher;
o reverse deviotion -
minus reoding -
connot procticolly
occur). By
subtrocting this deviotion from the meosure on
the gouge, the octuol distonce between the
pinion ground foce ond the geor
cross oxis will
be obtoined,
i. e. 60.00 mm minus 0.66 mm :
59.34 mm.
The meosure on the crown
wheel indicoting
the ossembly
distonce of the pinion
is, foi
exomple, 59.60. Accordingly,
the pinion
must be
moved slightly
out of the housing
0.26 mm, i.
e.,
by the difference
of the two
meosurings (59.60
minus 59.34:0.26 mm).
4. Prepore
odiusting
sirims 0.30 mm thick to
be inserted
under the flonge
of the pinion
beor-
ing on further
ossembly of the housing.
Shims 0.14, O.2, 0.3, ond 0.5 mm thick ore
ovoiloble. lf the required
occurote outword shift-
ing of the pinion
connot be ochieved
with shims
of ony of the specif
ied thickness, combine them
to obtoin
the next higher
volue.
Note: The thickness of shims required
for the od-
iustment of the
pinion
con be olso
colculoted
in the following
woy:
o) Set the diol indicotor
of the Mp 5-103 gouge
os in porogroph
1of the preceding
texi i.6.,
with the gouge
odiusted on the meosuring
contoct, the reoding
of the diol indicoto-r
will be 1.00 mm.
b) .Swing the
tip of the diol
indicotor
ogoinst
the pinion ground foce ond push
the
iinion
by meons
of the Mp 5-102
beorinq
retoiner
into the housing
till the diol
indicitor reods
1.00 mm. pointer
ofter pushing
the pinion
into the
housing is the meosure (thickness)
of the
shims.
4.9 DIFFERENTIAL
Assembly 1. Instoll the sun geor (plonet)
without the
friction wosher, the two stor pinions
(sotellites),
ond the pilot pin
for the stor pinions
into the
left-hond holf of the differentiol cose (with
the
flonge for the crown wheel). The originol
dif-
ferentiol pinion
shoft pressed into the cose
must be reploced tempororily by the pilot
pin
to focilitote hondling. 2. Push the sun geor
from outside into
en-
gogement with the stor pinion
teeth ond
use
o depth gouge
to meosure the dimension by
which it protrudes
from the housing. Then, pro-
ceeding from inside, push
the sun geor
into the
obutment surfoce of the differentiol cose ond
meosure ogoin
by how
much lt protrudes
from
the housing. The difference of both meosure-
ments determines the gop
for the sliding ring.
The rings ore supplied
in thlcknesses of 1.8,
1.9,
2, 2.1,2.2, ond 2.3
mm. Select the ring whlch is
0.1 mm thinner thon
the colculoted dimension
of the gop.
Fig. 4.9/1- Sectionol View of Differentiol
The orrow points to the mork indicoting the
side for pressing-on
the differentiol pinion
shoft. Any symbol con be used (o
figure, o let-
ter) but it must be identicol for both ports
of
the differentiol. lt olso indicotes the
correct
relotive position of the two differentiol ports.
c)
d) Push,
the pin-ion further into the housing
{while w.otching
the deflection
of the poin-.
ter) until the ossembly
meosuring
is ob-
toined (the 59.60 meosure
on th; crown
wheel) , i.
e., by the dif ference
of this
meosuring from 60.00
mm -
in our exomple
60.00 minus 59.60:0.40
mm.
Without chonging the position
of the
diol
Indicotor, push
the pinion into the housing
gs for os
it
will go -
the difference
of th6
d.iol reoding
from the previous
0.40 mm is
the thickness
of the required
shims (0.26
mm). Or, without chonging
the position
of
the diol indicotor on tfrJ pinion,
trin tf,e
scole to zero (0).

The most importont points

of
view of driving ore the

by
the oxle design.
Adiust first the comber
ond then the toe-in
since o chonged comber
offects the toe-in.
We refroin from describing in detoil ony
meosuring method in view
of the lorge number
of existing gouges.
Insteod,
we odvise you
to refer to
the procedures recommended
by the
monufocturers of the gouges.
The check lood con be formed by blocking the
wishbones with bors occording to
Fig. 6.1/5.
Press down the cor with the hond, insert
the
bors under the wishbones so
thot they
beor
ogoinst the oxle brocket, ond releose the cor
to
let the bors be clomped. lf
clomping of the
bors
does not toke ploce
(which con hoppen on on
older cor with weokened springs),
consider the
condition os if the bors were
clomped, i. e',
corresponding to the position of the
front oxle
ot check looding.
The words "ot
full lood" describe o vehicle
looded so thot the distonce of the rubber deod
stop from the bottom of the
lower wishbone
stop is 20 mm (see olso porogroph
18) ond the
comber ongle of the reor wheels is 1". Meosure
these volues on oll wheels (not
only one front
ond one reor wheel) ond distribute the
lood os
necessory.
Toe-in To odiust the toe-in, screw
the right-hond ond
left-hond steering rods
symmetricolly (o
chonge
up to 1 mm con be effected by
one rod) ot
check lood so thot the distonce between the
wheel rims (or
ocross them) behind the oxle
(A+o) is lorger by the toe-in volue (o)
thon the
distonce between the rims
in front of the oxle
(A). To verify steering symmetry (correct screw-
ing of steering rods during
toe-in odiusting),
check the wheel lock position ot the
20" lock
ongle of the neorside wheel -
for the respective
volues refer to Chopter 1.7.
Slocken the steering rod
nuts ond rotote the
steering rods using on
olligotor wrench (Fig.
6.1/6). In oddition to the correct inflotion
pressure
of the tyres, poy
ottention to
severol essentiol
points when checking the wheel
olignment:
o) Ploce thewheel in the stroight oheod trovel'
ling direction;
b) The
steering rod ond the trock rod
must
not
be stressed. The stress con be eliminoted by
letting the cor swing
up ond down in its
suspension under the pressure of
your
honds
(olternotely press down ond releose
the
wings)
c) Prepore the oxle os
shown in Fig.6.1/5;
d) lf
o speciol gouge with
o scole for wheel

You will find the respective volues
in Chopter

Prising off Door Ponel
When it is roining or when woshing the cor,
woter runs down the gloss
ond penetrotes
into the inner spoce of the door. The
foil is
supposed to prevent
the forming of under-
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
of the insulotion
(foil), the inner end, inside the door, ond
then opply o seoling compound on to
the
door inner metol-sheet ponel
ond the insu-
lotion os indicoted in the illustrotion (block
dots ) .
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:
height of door in relation to door ap_erture.
2. In and out after slackening bolts. Result:
Position of
the door leading edge in
relation to bodY aPerture'
3. Shims Pt.
No. 1 13-98B9OO between
hinges and pillar
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
of the door'
