Roof Sealing and Wind Noise
Roof Sealing and Wind Noise
Roof seals and side windows have been provided
with
a range
ofadjustments capable ofdealing with
any leaks which may occur.
The following information is divided into five
sections:

1.
A post and header sealing/roof lock adjustment

2.
Roof seals - adjustment
3. Cheater plate seals - adjustment/renewal

4.
Door glass - adjustment
5. Rear quarter glass - adjustment (9.1.01.2)
When a leak is
reported,
either wind noise or water
ingress, try to pinpoint the actual leak path using
any of the following methods:
• An ultrasonic leak detector
• An air flow
detector,
e.g.
Drager
smoke
tube
• Paper test strips at seal contact areas
9.2.01.5 - 'A' Post/Header Sealing and
Lock Adjustment
when a leak is detected at the top of the 'A' post
adjacent to the header rail
seal,
first
ensure
that the
roof lock is correctly adjusted.
If the lock is difficult to operate, it is probably
overtensioned. Release the retaining hook locknut

and extend
the hook
one full
turn.
Checkand repeat
the adjustment as necessary.
If the locking handle is loose, it is undertensioned.
Release the retaining hook locknut and screw the
hook inwards one full
turn.
Check and repeat the
adjustment as necessary.
Open the roof and check for obvious seal defects
i.e. collapse, damage or manufacturing faults.
Replace where necessary.lf the lock tension is
correct and a leak is still evident, it may be caused
by lack of pressure between the front frame and
header seals (Fig 2).

Increase seal pressure by inserting a
packer between
the front and rear frame seals (see DB7 Volante
parts manual).

Note:
After fitting
sea!
packers, check the locking
handle tension and adjust if necessary. If
a
leak is
still evident, go to 9.2.01.6.

Roof Seals - Adjustment
9.2.01.6 - Roof
Seals
- Adjustment
Seal adjustment is done in two stages. First stage -
lateral adjustment, and second stage - outward
adjustment. Seals are packed out using selected
packing strips.
Lateral Adjustment
Partially open the roof.
Front frame seal only: Remove the seal retaining

plate.
Remove the seal from the channel.
Slacken the channel securing screws and reposition
the channel as required, moving it on the slotted
screw holes (Fig 3-A). Tighten the channel securing
screws.
Apply soft soap to the seal and insert the outer seal
edge into the channel. Then press in the inner edge
to fully seat the
seal.

Refit the seal retaining plate.
Outward Adjustment
Partially open the roof.
Remove the seal retaining plate. Remove the seal
from the channel. Mark the position of the channel
for reference, release the screws and remove the

channel.

Select the appropriate packing (Figure 3-B)(see
DB7 Volante parts manual):
Rear frame seal foam strip
Front frame seal foam strip
Main column seal foam strip
Upper 'A' post seal foam strip
Note: The foam strips are for full length packing. For
packing at one end
only,
a shorter rubber
wedge
can be
used. (Fig 1-C)
Fit the foam strip/rubber wedge and channel. Align
the channel in the previously marked position. Fit
and tighten the securing screws.
Apply soft soap to the seal and insert the outer seal
edge into the channel. Then press in the inner edge
to fully seat the
seal.
Refit the seal retaining plate.
Note: It is imporrtant at all times to retain the overall
shapeoftheroofsealline(Fig4).
Wherea
leak necessitates

the
adjustment of only
one
or two
seals,
ensure
that
there
are
no
misalignments.
A more
satisfactory result
may be
obtained by adjusting the adjacent component, i.e. the
door
glass
or rear quarter glass.
The relationship between the roof seals is very
important. Two seals in very close contact will
promote leakage problems. Sealing will be far more
effective ifthe seals touch lightly or exhibit a small
air gap (Fig 4).

Cleaning of Alcantara Trim
Cleaning of Alcantara Trimmed Roof Lining and Interior Components
Recommendations

1.
Clean the stain immediately.
Clean the stain working from the edge to the centre of the spot to prevent a ring forming.
Delicately remove most of the dirt with a blunt scraper and immediately blot the spot with a clean white cloth.
Once you've identified the type of stain, follow the instructions in the spot removal chart.
Never pour a solvent directly on the spot; instead pour the solvent on a clean cloth.
After you've applied the spot remover, remove it with a dry clean cloth. Afterwards, brush the area against the
material nap.
7. Let the spot dry. Do not sit on a humid part. Afterwards, vacuum the spot with a vacuum cleaner.

Washwithmildsoap. If the stain persists, blot with denatured alcohol or ammonia diluted
at 10%.
Blot with lukewarm water (max 50°C) or with ammonia diluted at 5%.
Oil Paint - Blot with ethyl alcohol then wash with mild soap.
Water Based Paint - If the stain is fresh, blot with cold water. An old stain is very difficult
to remove, consult a specialist.
Apply ethyl alcohol or perchloroethylene, then wash with mild soap. If the stain persists,
use ammonia diluted at 5% or denatured alcohol.
Blot with lukewarm water (max 50°C) then wash with mild soap.
Blot with acetone.
Remove as much as possible with a paper towel. Blot with a solution of 30% denatured
alcohol and 70% water, then wash with mild soap. Lemon juice also gives good results.
Blot with lukewarm water (max 50°C). If the stain persists, use ethyl alcohol or
perchloroethylene
Blot with denatured alcohol, then wash with mild soap.
Blot with perchloroethylene and denatured alcohol.
Blot with water and vinegar (50%), then wash with mild soap.
