Actuator Dust Cover – Maserati Cambiocorsa Duoselect MC-Shift
This is a brand-new gear actuator dust cover made of aircraft grade aluminium. The set also includes a new flat gasket. This upgrade part replaces the original dust cover, which is made of plastic and often breaks.
Clutch Pressure Sensor – Maserati Duoselect / MC-Shift
The clutch pressure sensor provides a signal of the hydraulic pressure on the clutch engagement hydraulic line. This is a brand-new spare part.
Hydraulic Lines – Maserati Cambiocorsa Duoselect MC-Shift
This is a complete set of brand-new hydraulic lines for the Maserati F1 transmission (Cambiocorsa, Duoselect, MC-Shift). Including lines for EV1, EV2, EV3, EV4, EV5 and EVF.
All lines are made in Germany and come with a black protection coating.
Pentosin CHF 11S
Pentosin CHF 11S is a synthetic high performance hydraulic fluid for life-time application in modern vehicle aggregates. Pentosin CHF 11S is especially designed for hydraulics in the automotive industry with the highest technical requirements such as in: power steering, level control, shock absorber, hydro-pneumatic suspension, stability and traction control, hydraulics for convertible tops, central lock systems, etc.
It is suitable for all extreme conditions and guarantees full performance from -40 Degree Celsius to over 130 Degree Celsius system temperature.
Pentosin CHF 11S meets DIN 51 524T3 and ISO 7308 specification standards.
PPV Solenoid Valve – Maserati Cambiocorsa Duoselect MC-Shift
The valve block / power unit of the Maserati Cambiocorsa / Duoselect / MC-Shift system contains 6 solenoid valves.
- EVF (QPV) – clutch engagement
- EV1 (PPV) – gear engagement
- EV2 (PPV) – gear engagement
- EV3 (QPV) – gear selection
- EV4 (QPV) – gear selection
- EV5 (QPV) – gear selection
Photo for demonstration purpose only. The valve may come without sticker label. Depending from model and year of construction the numbers on the sticker label may vary. In case you are not sure if the part fits your car, please contact us before you buy.
Pressure Accumulator – Maserati Cambiocorsa Duoselect MC-Shift
The pressure accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. This piston type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a Nitrogen gas filling which creates the counterpressure. Both cells are separated by a moving piston. Typical symptoms of a faulty pressure accumulator are frequent and short pump cycles. If there is no more preload pressure left in the accumulator, the pump runs every few seconds, which ultimately leads to a consequential damage of the pump motor. Along with the pump motor, a faulty pressure accumulator is one of the most common causes of pressure build-up issues and is one of the few wear parts in the system that should be regularly checked and replaced if necessary.
We offer a brand-new replacement accumulator.
Pressure Relief Valve – Maserati Cambiocorsa Duoselect MC-Shift
The pressure relief valve is responsible to prevent damage to other components due to excess pressure in the hydraulic system. A defective valve would cause pressure loss and frequent pump cycles (similar symptoms as a worn pressure accumulator).
Pressure Sensor – Maserati Cambiocorsa Duoselect MC-Shift
The pressure sensor is responsible to measure the hydraulic pressure in the accumulator. This is an original and brandnew spare part.
Pump Motor – Maserati MC-Shift
The pump motor drives the gear pump, which generates the pressure for the MC-Shift transmission. Both parts together form the hydraulic pump. Without hydraulic pressure, the transmission cannot perform any action – neither change gears, nor operate the clutch. Therefore, the hydraulic pump is the most important component in the system.
In most cases, it is sufficient to replace only the electric motor, as this is a wearing part. The gear pump fails only very rarely. Another advantage is that when only the pump motor is changed, the hydraulic system does not need to be bled afterwards, unless it has been opened.
We sell an original, brand new Magneti Marelli spare part – the same part you would get from Maserati.
Pump Relay – Maserati Cambiocorsa Duoselect MC-Shift
The pump relay is responsible to switch on / off the hydraulic pump. A broken relay causes the pump to fail priming. Without hydraulic pressure, the system cannot engage the gears or clutch.
QPV Solenoid Valve – Maserati Cambiocorsa Duoselect MC-Shift
The valve block / power unit of the Maserati Cambiocorsa / Duoselect / MC-Shift system contains 6 solenoid valves.
- EVF (QPV) – clutch engagement
- EV1 (PPV) – gear engagement
- EV2 (PPV) – gear engagement
- EV3 (QPV) – gear selection
- EV4 (QPV) – gear selection
- EV5 (QPV) – gear selection
Please note: The product photo is for illustrative purposes only. The valve may be supplied without a sticker label. Depending from model and year of construction the numbers on the sticker label of your original valve may vary. The valve supplied by us replaces QPV02 and QPV10 valves, but not QPV14. In case you are not sure if our part fits, please contact us before you buy.
Service Kit Hydraulic Pump – Maserati MC-Shift
The service kit includes the plastic coupling, which connects the shaft of the gear pump with the shaft of the electric motor, as well as seals.
