The clutch pedal is connected to the master cylinder, which, together with the hydraulic fluid reservoir, is mounted on the bulkhead of the engine compartment on the driver's side. When the pedal is pressed, the force moves the hydraulic fluid forward into the slave cylinder. The piston in the slave cylinder moves the clutch release fork, which moves the release bearing. The release bearing rests against the heel, as a result of which the action of the diaphragm spring weakens and the clutch disengages (the primary shaft is disconnected from the engine).
As the friction disc wears, the gap between the friction disc and the pressure disc is selected automatically.
Caution! Access to the clutch components is difficult, so each time you remove the engine or transmission, carefully inspect the clutch discs and release bearing. Replace these parts if necessary. The friction disc must be replaced, regardless of its condition.
