ond the slip-over ring in posltion.
Fit the

with the idler must
move freely olong the shoft.
2. Slip the respective
woshers on the shoft in
their originol sequence (corrier

ormoture with the engoging lever
into the drive

lightly. Fit the lever pin
into the drive

Connect the terminol "30'of
the storter
motor to o properly
chorged bottery ond incor'
porote on ommeter with o wide
meosuring ronge
into the circuit -
see Fig. 13.10/3.
Stort the
engine (feed
current to the terminol "50").
The
volue of the current ot idling speed must
not
exceed 65 omperes (not
considering the peok
ot
the first momentous deflection).
The storter motor must run noiselessly,
smoothly, ond the pinion
must move smoothly
into ond out of the rest position
(engoge
ond
diesengoge). The engoged pinion
must not ro-
tote direct on the foce of the slip-on ring. The
run-out of the storter motor must not lost longer
thon 8 seconds ofter the disconnection of the
switch from the current supply.
Inspect the brush pressure
springs. The
brushes must
beor on the commutotor by ot
leost two thirds of their surfoce ond they must
move freely in their cells.
The ormoture should hove o noticeoble oxiol

At
o slight rototion of the pinion
in the direction
of the storter motor rototion,
the idlor must

6. Fit the spring on the motor shoft,
support
the shoft
to ovoid domoging the beorings, ond
press-on the impeller. The cleoronce between
the impeller circumference ond the brocket
must be smoll,

by pressing -
on the lock ring
- ogoin the motor shoft
must be supported.
7. Close the motor beoring from obove by

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

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:

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
