2585401 - Introduction - CLUTCH

The clutch is the dry, single plate type with a thrust bearing always in contact with the flexible coupling spring.The driven disc is driven by the pressure exerted by a diaphram spring. The clutch is released by a pedal-operated hydraulic system.

The system consists of:

• a reservoir (1) common to the brake and clutch systems,
• a clutch pump (master cylinder) (2), which has the task of compressing the fluid and is fixed to the pedals;
• a connecting pipe (3) between the pump and the clutch operating cylinder;
• a clutch operating cylinder (4) fixed to the gearbox;
• linkage (5) operating the thrust bearing;
• a thrust bearing (6);
• a clutch drip tray with diaphragm springs (7);
• a clutch plate (8);
