Figure 7-2 - Clutch operation.
There are two types of clutch operating
systems: mechanical and hydraulic. The
mechanical system is the most common and
uses a rod type of linkage (
Figure 7-3
); other
mechanical systems use a flexible type of
cable (
Figure 7-4
). These systems are
normally found in automotive applications. The
hydraulic operating system (
Figure 7-5
) moves
the release lever by hydraulic pressure.
Depressing the clutch pedal creates pressure
in the clutch master cylinder, actuating the
slave cylinder which, in turn, moves the
release arm and disengages the clutch.
Hydraulic types of clutch operating systems
are normally found in heavy construction
equipment where extreme pressure is required
to operate the clutch.
