operation. Circuit pressure between 42 and
52 bar at 20°C.
3. Oil Reservoir:
It contains the hydraulic oil of the system and
bears the maximum and minimum level
marks.Tutela CS Speed type oil.
Warnings:
Do not contaminate the Tutela CS Speed oil
with impurities. Do not mix the Tutela CS
Speed oil with other types of oil.
Electro hydraulic Unit (2):
Its functions are:
To operate the CSC clutch;
To operate the gear control shaft (selection
and engagement movements);
To maintain a hydraulic energy/power re-
serve for efficient operation of the
actuators.
The hydraulic unit comprises:
A fusion body fixed directly to the gearbox;
Two proportional pressure solenoid valves
EV1 (2) and EV2 (3) for gear engagement
actuator control;
Two on-off solenoid valves EV3 (3) and EV4
(4) for controlling the position selection ac-
tuator;
A proportional flow rate solenoid valve EV0
(1) for the clutch actuator control;
A pressure sensor (6);
A sensor (8) for measuring the engagement
actuator position;
A sensor (7) for detecting the selection ac-
tuator position.
