DOOR WINDOW AND GLASS
FRAME ASSEMBLY
REMOVAL:
1. Remove all inside trim and hardware from door. See
Page 81.
2. With window in lowered position, loosen the 7/16 hex
head bolts attaching window rest channel to regulator
upper cross member. These bolts are located behind the
side members of the regulator assembly and are accessible
thru the bottom opening of the inner panel.
NOTE: These bolts need only be loosened as the tabs
on the lower glass rest channel are slotted.
3. Slide window and frame assembly up and out of the top
of the door.
INSTALLATION:
Reverse procedure of removal and adjust window as
described under "Convertible Top and Window Adjust-
ment," Page 86.
NOTE: Removal and installation procedure is the
same for both hydraulically and manually regulated
windows.
FIGURE 117
DOOR WINDOW REGULATOR
CYLINDER
The door window regulator cylinder unit, Figure 117,
consists of a tubular cylinder which is closed at one end
by
by a crimped-in formed cup which houses a saturated
felt. This felt prevents the entry of dirt or water to the
upper portion of the cylinder and lubricates the piston
rod. The upper end of the piston rod (2) is mushroom
shaped and fits into a formed seat on the cross arm. It
is held in position by a spring steel retaining clip. At
the lower end of the rod (3), an assembly of metal and
synthetic rubber washers form the piston assembly.
The lower end of the rod is riveted over to form a unit
construction.
The lower end of the cylinder is closed by a spring
seated, normally closed, solenoid operated valve (4),
which, when electrically energized, opens to allow
fluid to flow in or out of the cylinder. When closed,
this valve traps the fluid in the cylinder, retaining the
window in any desired position.
The piston in its extreme position is stopped on the
solenoid sleeve to limit the movement of the window
glass when fully lowered.
The solenoid assembly is provided with a synthetic
rubber sealing ring at its upper end above the winding.
This ring makes a leakproof seal for the lower end of
the cylinder. The cylinder is crimped over to provide
unitary construction.
A short wire lead extending from the lower end of the
cylinder is provided with a bullet type terminal to
which an electrical connection is made to operate the
solenoid. The solenoid is grounded thru a wire sol-
dered to the outside of the cylinder.
A boss (7) containing 1/8" internal dry- seal pipe
threads for the hydraulic line connection is formed at
the lower end of the sleeve. A mushroom-shaped,
pressed in stud (8) at the extreme lower end provides
a ball joint mounting identical to that at the upper end
of the piston rod.
The upper end of the cylinder barrel is lubricated
permanently with a synthetic graphite compound, and
since the cylinder assembly is sealed with crimped-in
ends, no repairs to the internal parts are possible.
When service is required the entire cylinder unit must
be replaced.
