Rear Quarter Glass Adjustment "^^
9.1.01.2
-
Rear Quarter Glass Adjustment
The rear quarter glass can be adjusted in three
planes, Lateral, Up and Down, and Front to Rear.
During initial assembly, assuming that the door is
correctly gapped and profiled, the door glass is set
to the upper 'A' post seal and the front frame
seal.

The rear quarter glass is then set to the door glass.
Both glass tops should be accurately aligned and
there should be a minimum 2mm gap between the
glasses. Any minor adjustments are then made
using the following procedures.
Lateral Adjustment
Remove the rear quarter trim panel. Remove the
adjuster stud locknuts and special washers (Fig 7-

A).
Using a 5mm box spanner, rotate the adjuster
screw clockwise to move the glass inboard or
anti­

clockwise to move the glass outboard (Fig 7-B).
Refit the special washers, refit and tighten the
locknuts. Refit the rear quarter trim panel.
Front to Rear Adjustment
Remove the rear quarter trim panel. Loosen the
three adjuster stud locknuts. Adjust the glass front
to rear
as
required (Fig 7-C). Re-tighten the locknuts.
Check and readjust as required. Refit the rear
quarter trim panel.
Up and Down Adjustment
Remove the rear quarter trim panel. Slacken off the
lockbolt (Fig 7-D) two ro three turns. Adjust the
vertical position of the glass
as
required. Re-tighten
the lockbolt. Rechecktheglass position and readjust
as required. Refit the rear quarter trim panel.

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.
