CLUTCH
General Description
Both the Cadillac and LaSalle clutches are of
the dry-disc type. They differ in construction,
however, but are serviced in somewhat the same
manner except that the LaSalle clutch may be
completely serviced in the field.
The factory does not supply any of the component
parts of the various pressure plate assemblies
for the Cadillac clutch, inasmuch as specially
designed equipment is necessary to adjust the
assembly properly. The only individual parts
furnished for this clutch are the driven discs.
When any of the other parts need replacing, it
will be necessary to install a complete clutch
assembly.
CADILLAC CLUTCH
The clutch used on Cadillac cars has three
driving plates and two driven discs. The center
driving plate carries four driving studs which
extend through both the front and rear plates.,
The rear plate is a part of the spring pressure
plate assembly which also includes the release
mechanism. The springs are carried in supports
which are riveted to the rear driving plate at two
points and in addition is provided with two extensions
or legs to provide a four-point contact with
the driving plate.
A double-lever release mechanism is used on
the 452-D clutch to avoid springiness in the levers
and pressure plate, insuring uniform engagement
of the clutch over the entire surface of the facings.
The driven discs for the 370-D clutch have
curved spokes. All other clutches use discs with
straight spokes.
The mounting of the clutch is extremely simple.
It is necessary to take off only four nuts to remove
the entire clutch assembly from the flywheel.
The service operations on the clutch are the
same on all Cadillac cars.
LASALLE
C L U T C H
The LaSalle clutch is of the single-plate type.
The clutch is released through a graphite release
bearing which is mounted on the clutch release
yoke. The release bearing contacts with a plate
attached to the inner ends of the release levers.
Each release lever is pivoted on a floating pin,
which remains stationary in the lever and rolls
across a short flat portion of the enlarged hole in
the eyebolt when the clutch is disengaged. The
outer ends of these eyebolts extend through
holes in the clutch cover and are fitted with
adjusting nuts by which each lever is located in
the correct position.
The outer ends of the release levers engage the
pressure plate lugs by means of struts, which provide
knife edge contact between the outer ends
of the levers and the pressure plate lugs, eliminating
friction at this point.
No adjustments for wear are provided in the
clutch itself. An individual adjustment is provided,
however, for locating the release levers in
manufacturing, but they are locked in place and
should not be disturbed, unless the clutch is disassembled
for the replacement of parts.
