When refitting the door, 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.
BR.11 - DOOR GLASS, GUIDE RAILS & WINDER MECHANISM - Manual Windows
A manually operated door window scissor type lift mechanism is used in conjunction with two steel guide
rails 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 edge 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. An extension to the primary scissor leg carries a toothed sector which
is engaged by a pinion on the window winder. The front and rear edges of the glass are guided by steel rails
which engage with point contact Nylon guide blocks bonded to the glass. The bottom ends of the rails are
adjustable in/out to set the inward tilt of the glass, with the 'up' glass position controlled by an eccentric stop on
the winder mechanism.
Door glass adjustment
To adjust the door glass for optimum weather sealing and ease of operation:
1. Fit the soft top roof and fully raise the window. Check the alignment of the top edge of the glass against
the seal, and the seal compression along the cant rail and up the 'A' and 'B' posts. A light compression is
required; just sufficient to ensure sealing, without imposing loads on the winder mechanism.
2. To adjust the inward tilt of the glass, screw the adjusters at the bottom of each guide rail in or out as
necessary. Access is available without removing the door trim panel. Check that the window glass
moves freely throughout the range of travel.
