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).
