3. To tilt vent wing inward insert a washer or washers
between wing cradle and inner panel at the upper wing
cradle attachment screw (S). Install and tighten both
screws. (To tilt outward, insert washers at lower attaching
screws (S)).
4. Tilting the glass inward moves the bottom of the center
glass channel away from the inner panel. Washers should
be inserted between the lower end of the channel (U) and
the inner panel, to hold channel in position. Retighten
screws (T) and (U).
HYDRO-LECTRIC SERVICE
INFORMATION
The operation of the hydraulic top and window units in
the Hudson Convertible Brougham is accomplished
through the use of a electrically operated hydraulic pump,
single action hydraulic window cylinders, and double
action hydraulic top operating cylinders. The electric
pump motor is operated through a solenoid switch on the
side of the motor, and each window cylinder is operated
through a solenoid switch incorporated in the cylinder.
To make a complete check, both the ELECTRICAL sys-
tem and the HYDRAULIC system must be considered.
The hydraulic system includes the hydraulic pump, pres-
sure relief valve and fluid reservoir, the top operating
valve, top and window operating cylinders, fluid lines,
and the hydraulic fluid. The electrical system includes the

battery, circuit breakers, top operating valve and switch
assembly, window switches, motor solenoid, motor, win-
dow cylinder solenoid valves, and all connecting wires.
The first step in checking any Hydro-Lectric system that
fails to operate, or which operates slowly, is to check the
battery gravity reading, Figure 146. For efficient opera-
tion, the battery reading should not be lower than 1225. A
low battery may result in slow operation of the pump
motor or faulty operation of the motor solenoid switch and
the window cylinder solenoid valves.
CAUTION: Before any check of fluid level, disconnect
negative cable at negative battery terminal. Since the
hydraulic fluid is inflammable, any accidental sparks
may ignite spilled fluid.
If the pump motor operates and the battery gravity reading
is at least 1225, unsatisfactory operation may be due to
low fluid level in the fluid reservoir. Low fluid level is
usually indicated when the pump operation is noisy or
when it is impossible to raise all the windows; that is, one,
two, or three windows may go up satisfactorily, but pump
may become noisy and only partially close the fourth
window while the other three are up.
To check the fluid level in the reservoir, lower all win-
dows and raise the car.
