operates the clutch release yoke thru a sheathed ca-
ble attached directly to the upper end of the pedal
lever. Pedal return is accomplished thru the cable by
the clutch yoke return spring at the transmission.
The pedal return stop
is
a nonadjustable rubber
bumper inserted through the upper end of the pedal
leverjust below the cable attaching point. The clutch
cable is sheathed in woven steel and weather pro-
tected by a plastic and fabric covering. An eyelet is
wedged on the upper end and fits over a formed
hook on the upper end of the pedal. The lower end
is provided with a
ball stud arrangement
that slips into a slot in the clutch release lever. See

Opel 1900 and Manta
The pedal lever pivots on a tubular steel shaft and
operates the clutch release yoke through a sheathed
cable attached directly to the upper end of the pedal
lever. Pedal return is accomplished through a spring
attached to the pedal below the pivot shaft and to the
pedal assembly mounting bracket at the bulkhead.
Clutch actuation works without pedal-free travel and
a warning device is provided which actuates an in-
dicator lamp in the instrument panel indicating
necessity of clutch adjustment. The clutch cable is
sheathed in
w o v e n steel and weather protected by a
plastic fabric covering. An eyelet is wedged on the
upper end and fits over a formed hook on the upper
end of the pedal. The lower end is provided with a
wedged ball stud arrangement that slips into a slot
in the clutch release lever. See Figure
Clutch Mechanism
The clutch assembly is enclosed in the bell housing.
The clutch release bearing and release fork are of
conventional design, with the fork pivoting on a ball
stud located opposite the control cable attaching
point. The bearing flange tits over two vertical pins
which are riveted to and extend into the eye of the
yoke.
The clutch pressure plate is similar in design to the
Buick Century pressure plate. A radially slotted dia-
phragm pivoting on two steel wire rings is retained
to the clutch cover by eight rivets. The clutch driven
member is a
inches diameter single plate dry
disc with torsional damper springs and spring leaves
between facings to cushion application. Dampener
springs in clutch disc assembly are
