Hydraulic Components
The hydraulic system consists of a hydraulic unit, two hydraulic cylinders, and the hydraulic lines. The system operates at pressures of up to 140 bar.
The hydraulic unit is made up of the motor driven pump as well as the oil reservoir. The direction of oil flow can be reversed by changing the polarity of the electric motor that drives the pump. The hydraulic cylinders consequently extend and retract.
The convertible top is folded down when the hydraulic cylinders are extended and closed when the hydraulic cylinders retract.
After topping up the oil reservoir with hydraulic oil (e.g. after repairs) particular care must be taken to ensure that the transparent reservoir is completely full. Only use MINI approved oil for this purpose. It is not necessary to bleed the hydraulic cylinders. The system is self-bleeding by operating the convertible top several times.
