12:1 Bodywork finish
Large scale repairs to body panels are best left to
expert panel beaters. Even small dents can be tricky, as too
much hammering will stretch the metal and make things
worse instead of better. Filling minor dents and scratches
is probably the best method of restoring the surface. The
touching up of paintwork is well within the powers of
most car owners, particularly as self-spraying cans of
paint in the correct colours are now readily available. It
must be remembered, however, that paint changes colour
w i t h age and it is better to spray a whole wing rather than
try to touch up a small area.
Before spraying it is essential to remove all traces of
wax polish with white spirit. More drastic treatment is
required if silicone polishes have been applied. Use a
primer surfacer or paste stopper according to the amount
of filling required, and when it is dry, rub it down with
400 grade Wet or Dry paper until the surface is smooth
and flush with the surrounding area. Spend time on
getting the best finish as this will control the final effect.
Apply the retouching paint, keeping it wet in the centre
and light and dry round the edges. After a few hours of
drying, use a cutting compound to remove the dry spray
and finish with liquid polish.

12:2 Interior and chrome cleaning
The cloth upholstery of the seating and the rear
compartment lining must be regularly cleaned to ensure
long life and preserve its attractive appearance. Any dust
or dirt that is blown into the car will settle on the uphol-
stery and will tend to wear the cloth causing an unsightly
appearance. It is recommended that the dust is wiped off
using either a vacuum cleaner or a stiff brush. To remove
ordinary soiling of the upholstery cloth proceed as
follows:
1 Using luke warm water and a neutral soap and a piece
of clean cloth wipe over the upholstery in the direction
of the nap.
2 Repeat the operation using a clean damp cloth and
warm water but no soap.
3 Allow the upholstery cloth to dry, use a stiff brush
against the direction of the upholstery nap to restore
its original fluffy look.
To obtain best results, any stains must be removed as
soon as possible otherwise as time passes they will
become more difficult, if not impossible to remove.
Certain stains require specific solvents and the instruc-
tions must be strictly adhered to.

Cleaning imitation leather:
To keep the imitation leather clean wash in luke warm
water and a neutral soap applied with a soft cloth. Wipe
clean with a clean moistened cloth with no trace of soap
and finally rub with a clean dry cloth until the original
lustre is restored.

Chrome plated parts:
To ensure long life from the chrome plated parts these
should be periodically washed using a cloth dampened
with petrol and dried with a soft cloth. Rub with a cloth
moistened in clean oil especially around the edges of the
components and finally rub using a clean dry cloth until
all traces of oil have been apparently removed.
Glass panels:
The glass panels must be cleaned w i t h a chamois
leather or rag. Take care that no abrasive material is
allowed to be rubbed onto the glass otherwise it will be
scratched.
12:3 Door trim and accessories
The rear-hinged doors have welded upper and lower
hinge halves being joined by a fulcrum pin to the other
half of the hinge which is welded onto the body. Upon
reassembly of a hinge the fulcrum pins must be fitted with
the ball head uppermost. With front-hinged doors the
hinge is bolted to the body pillar.
Check strap (earlier models):
To limit the door opening, a rubber check strap is fixed
by four self-tapping screws of which two are located on
the door and t w o on the body. When a check strap is being
fitted the following points should be noted:
1 Always use sealing compound on the check strap
mounting holes to ensure a moisture t i g h t j o i n t .
2 Insert the screws in the plates and in the strap.
3 Always place a washer on each screw between the
body and the check strap, and also the door and check
strap. Tighten the screws fully.
Weather strip:
A one-piece moulded weather strip is fitted to the door
aperture and fixed by a special adhesive. Should the
weather strip become detached or a new one requiring to
be fitted proceed as follows:
1 Remove the old weather strip as necessary and thor-
oughly clean the door opening flange with petrol,
remove any rust spots and touch in the paint work.
2 Clean the new weather strips of their preservative or
the original from road dirt using petrol and thoroughly
wipe
clean.
3 Apply a coat of adhesive using a brush to the side to be
attached to the body. Allow to dry for the recom-
mended period of time and position the weather strip
on the door opening flange ensuring that it is not
distorted. The joint should be on the bottom side of
the rear end of the door opening. Apply a heavy
pressure on the weather strip starting from the centre
and working towards the ends.
Two rubber lining strips are located on the door flange
and these should be attached using the same procedure
detailed above.
Ensure that the bonding of the rubber weather strips
to both the door opening flange and the door panel is
thoroughly dry before the door is closed, otherwise this
could be the cause of subsequent water ingress.

Inner panels:
Imitation leather-lined masonite trim panels are fitted
to all versions of the new 500' models. The panels are
secured in the housing below the door window by means
of four stiff clips located at the top and seven spring clips
located at the bottom equally spaced around the panel
border. The fasteners are located in holes in the door
framework inner flange. The door framework has a plate
which should be bent downwards onto the trim panel
once it has been installed. This will ensure correct seating
of the trim panel in the door housing.
When the door trim panel is being reassembled ensure
that the tarred felt pad is cemented correctly on the door
inner flange so that any water that may seep in through to
the door interior from the window rubber weather strips
may be kept away from the trim panel which would
otherwise cause distortion and rapid deterioration.
12:4 Door handles and locks
The doors are provided with locks which are operated
by handles either from inside or outside the vehicle.
Removal of the lock is a straightforward operation but
upon reassembly the following procedure should be
followed:
1 Mount the handle assembly from the outside and
insert the washer onto the stud. Screw in the nut several
turns to allow correct handle-to-lock mating on final
fitting.
2 Arrange the locking handle dog so that it is horizontally
positioned and tighten the mounting nut.
3 Mount the lock to the door panel and secure w i t h three
screws and washers.
4 Fit the plate w i t h the t w o rubber guide blocks fastening
by the t w o screws.
Striker plates are fitted with shim adjustment to the
door pillars and are secured by three screws.
12:5 Removing window regulator and door glass
Window regulator:
Description:
The window regulator unit is of the lever and gear
control type which transmits crank movement to the
lifting lever using high ratio gears. When the operating
handle is rotated it rotates a pinion mounted on its shaft
which is in mesh w i t h a gear on the hub of which is
mounted a second pinion that meshes with the lever
toothed sector (refer to FIG 1 2 : 3) . At the end of the lever
a pin fitting locates in a guide rail mounted on the
bottom of the glass. When the crank is rotated in one or
other direction the glass is either lifted or lowered.
Regulator removal:
1 Depress the door lining panel so that the crank key may
be located. Remove the key and the crank handle.
2 Using a wide blade screwdriver prise off the trim panel
by inserting the blade between the panel and the door
frame taking care not to scratch the door paint.
3 Remove the intermediate protection lining.

reassemble the regulator to the door is the reverse
procedure to dismantling. The following points should
however, be noted:
1 Before the lining is refitted to the door panel ensure
that the regulator operates correctly. Ensure t h a t the
glass moves up and down in its channels without
excessive efforts required on the crank handle.
2 Once the lining is glued into place ensure that it
adheres evenly on the door so that the window
regulator operation is not interfered with at a later date
due to the lining becoming detached.
