General Description................................................................................
Service O perations...................................................................................
The coil spring single plate clutch is a dry disc type
and no adjustment for wear is provided in the clutch
itself. An individual adjustment is provided for locating
each lever in manufacturing but the adjusting nut is
locked in place and should never be disturbed, unless the
clutch is dismantled for replacement of parts.
When the clutch pedal is depressed the release bearing
is removed toward the flywheel and contacts the inner
ends of the release levers, (1) (fig. 9). Each release
lever is pivoted on a floating pin which remains station­
ary in the lever and rolls across a short flat portion of
the enlarged hole in the eyebolt (2). The outer end of each
release lever engages the pressure plate lug by means of
a strut (3), which provides knife-edge contact between the
outer end of the lever and the lug. The outer ends of the
eyebolts extend through holes in the stamped cover (4),
and are fitted with adjusting nuts (5) to correctly position
the levers.
