GENERAL DESCRIPTION
COMPONENTS
The principal parts of a clutch system are: the
driving member and the operating members. Figure
7C-1 shows an exploded view of the clutch system.
DRIVEN MEMBERS (FIGURES 7C-1 AND 7C-2)
The driven member is the clutch disc with a
splined hub which is free to slide lengthwise along the
splines of the input shaft, but which drives the input
shaft through these same splines.
The driving and driven members are held in
contact by spring pressure. This pressure is exerted by
a diaphragm spring in the pressure plate assembly.
HYDRAULIC CLUTCH (FIGURE 7C-3)
A hydraulic clutch operating mechanism is used
on all models. The
mechanism consist of a remote
reservoir, clutch master cylinder and slave cylinder.
The remote reservoir is mounted to a bracket which
bolts to the power brake booster. The clutch master
cylinder is mounted on the cowl panel and the slave
cylinder is mounted on the bell housing. The clutch
master cylinder is operated directly off the clutch
pedal.
When the clutch pedal is pressed down, hydraulic
fluid under pressure from the clutch master cylinder
flows into the slave cylinder. Since the piston is also
connected to the clutch fork this lever moves the
release bearing into contact with the clutch cover
release fingers to disengage the clutch. The hydraulic
clutch system locates the clutch pedal height and
provides automatic clutch adjustment. No adjustment
of clutch linkage or pedal position is required.
OPERATING MEMBERS (FIGURE 7C-3)
HYDRAULIC CLUTCH FLUID
When adding fluid to or refilling the system after
The clutch release system is operated by service operations use GM Delco Supreme No. 11 hydraulic pressure and consists of the clutch pedal, brake fluid or an equivalent fluid that meets DOT 3 clutch master cylinder, clutch slave cylinder, clutch specifications. fork and clutch release bearing.
NOTICE: Do not use mineral or paraffin base oil in
the Clutch Hydraulic System. These fluids will
damage the rubber parts in the cylinders.

procedure or glass breakage and
personal injury could occur.
The compartment lift window assembly height,
fore and aft and side adjustments are controlled at the
hinge-to-body location. This area of the body has
oversize hinge attaching holes (Fig. 3) in addition to
the hinge-to-body spacers. Adjustments at the hinge
location must be made with gas supports disengaged.
Additional height adjustment can also be made at the
lower panel by adjusting the rubber bumpers. Bolts
holding hinge to body should be tightened 20 to 28
N-m (15 to 20 ft-lb).

Removal and Installation
1. Prop lid open and place protective covering along
edges of rear compartment opening to prevent
damage to painted surfaces.
2. Use
a 13 mm socket to remove nuts holding glass
to hinge (Fig. 3).
CAUTION: Do not attempt to remove
or loosen gas support assembly
attachments with lid in any position
other than fully open as personal
injury may result.
3. While helper supports glass, disengage gas
supports from lift window assembly (view A, Fig.
4) and disconnect harness connector for electric
grid defogger (if present).
4. With
aid of helper, remove lift window assembly
from body and place on a protected surface.
CAUTION: When installing bolts
(glass to hinge), be sure to torque only
to
16 N-m (1 1 ft-lb). Overtightening
could cause glass to break and
possible personal injury. Always wear
safety glasses during this operation.
5. To install, reverse the removal procedure. Torque
bolt holding gas support to body 5 to
7 N-m (48
to 60 in-lb).
Removal of Compartment Lift Window Panel from Glass
CAUTION: When performing the
following operations, personal
protection
iterns such as safety
glasses and work gloves should be
worn to minimize possible personal
injury.
1. Place protective coverings around body opening.
2. Place two jackstands in body to support glass.
Place protective covering over jackstands.
3. Disconnect electrical connectors from gas
support (if present) and remove bolts retaining
gas support to lower reinforcement.
4. Lower glass.
5. Remove a. Wiper motor and blade assembly (if
present)
b. Gas supports
c. Lock striker
d. Nuts
holding lower reinforcement to panel,
starting with outboard nuts
(2, Fig. 5)
e. Screws
retaining lift window molding to
panel
6. Remove panel from glass.
a. Mask
off top forward edge of panel next to
glass.
b. Using
a flat-bladed sharp tool, cut out foam
and butyl sealing strips between panel and
glass (1 and 2, Fig. 6). Clean tool frequently
to ease cutting operation.
c. Using a sharp-bladed utility knife, cut
urethane between nylon patches and glass.
New patches will be required when
installing panel to glass.
