5.1 In a semi-hydraulic system
The clutch pedal arm operates a piston in the
clutch master cylinder (CMC). This forces hydraulic
fluid through a hydraulic hose to the clutch release
cylinder (CRC) where another piston operates the
clutch disengagement mechanism. When the
vehicle is equipped with a release cylinder, the
interface within the hydraulic system and the clutch
is operated by a clutch fork and a release bearing.
This system can be used both with push or pull type
clutches.
In a semi-hydraulic system, the release cylinder
is located outside the transmission housing. Thus
it is possible to replace the hydraulic components
without removing the gearbox.
