Clutch - Chevrolet 1956 Truck Operator's Manual

The freezing point of a solution containing both alcohol and
ethylene glycol cannot be determined accurately by means of
a hydrometer.
CLUTCH
Description. The clutch, which provides a means of disconnect-
ing the engine from the transmission while shifting gears, is
of the single plate dry disc type. The 6-cylinder engine clutch
consists of a pressure plate, cover, disc with facings, dia-
phragm type spring, throwout bearing, throwout fork and
small correlated parts. The 8-cylinder engine clutch uses heat
treated coil springs and release levers instead of the diaphragm
type spring.
Care. The Chevrolet clutch requires very little care or atten-
tion; however, proper use of the clutch will contribute mate-
rially to the carefree service it will render.
Never drive with the foot resting on the clutch pedal as
this causes constant wear on the clutch throwout bearing and
may cause slight clutch slippage which will cause premature
failure of the parts.
