beam to the extension bracket. Remove the bolts, noting any spacer washers used on the upper bolt
between the glass rear guide channel fixing bracket and the door beam, and withdraw the door assembly
off the beam.
Note that it is necessary to remove the drop glass inner waist seal before the glass may be withdrawn
from the door.

When refitting the door, remember to first fit the flange spreader plate onto the beam before mounting the
door shell. Take care not to scratch the glass if this is contained in the door. Insert the two rear bolts securing
the beam to the latch bracket, but do not tighten until the three fixings securing the front of the shell to the beam
flange have been fitted and tightened. It may be necessary to leave the tightening of the top rear fixing (also
secures the rear guide rail) after the glass has been fitted and the position of the rear guide rail adjusted.
BN.9 - DOOR GLASS. GUIDE CHANNELS & WINDER MECHANISM
A manually operated door window scissor type lift mechanism is used in conjunction with two aluminium
guide channels and a 'frameless' door design.
The operating principle of the window lift mechanism is that of a scissor linkage, with the front lower end
of the primary leg anchored to the door shell, the lower end of the secondary leg sliding in a horizontal channel
on the door shell, and the upper ends of both legs sliding in a channel fixed to the bottom of the window. The
geometry of the system provides for a parallel lift of the glass, where the angle of the bottom edge does not
change throughout the range of travel. A forward extension to the primary scissor leg carries a toothed sector
which is engaged by a pinion on the window winder. The glass is guided by front and rear, felt lined, alloy
channels, both of which are bolted to the door shell or beam, with various adjustments provided to control the
inward tilt of the glass, its up height, and the angle of the top edge.
