83. Rear Compartment Lid
Mechanical Closing Unit
The rear compartment lid mechanical closing
unit is used in conjunction with the vacuum lid
lock. It is designed to reduce the effort required
to close the rear compartment lid. Upon manually
lowering the lid and engaging the lid lock with the
striker, the mechanical closing feature pulls the
lid the remaining distance to the closed position.
To act as a safety feature and slow the action of
the closing unit a hydraulic cylinder is incorpo-
rated in the closing unit. The cylinder is attached
to a bell crank at the right rear compartment lid
hinge and to the closing unit by a cable. As the lid
is lowered and the lock latches to the striker, but
before the mechanical closing feature is tripped,
the piston extends to a "full-out" position. Then,
as the lid is lowered to actuate the mechanical
closing feature, the piston compresses the fluid in
the cylinder retarding the closing action of the
spring in the closing unit. Figures 16-81, 16-82,
and 16-83, show the mechanical closing unit com-
ponents and their adjustment locations.
