Accumulator – Aston Martin Vanquish ASM
The accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. The bladder type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a gas to create counterpressure. Both cells are separated by a membrane. These accumulators have a certain life span and a common defect is that the gas leaks out of the cell, which causes the system to be unable to build up hydraulic pressure. In many of such cases, the pump appears to prime permanently.
We offer the brand new original Magneti Marelli spare part.
Actuator Dust Cover – Aston Martin Vanquish ASM
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.
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 – Aston Martin Vanquish ASM
The valve block / power unit of the Aston Martin ASM 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 Relief Valve – Aston Martin Vanquish ASM
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 – Aston Martin Vanquish ASM
The pressure sensor is responsible to measure the hydraulic pressure in the accumulator of the ASM system. This is an original and brandnew spare part.
Pump Motor – Aston Martin Vanquish ASM
The pump motor drives the gear pump, which generates the pressure for the ASM 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 Aston Martin.
QPV Solenoid Valve – Aston Martin Vanquish ASM
The valve block / power unit of the Aston Martin ASM 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. In case you are not sure if our part fits, please contact us before you buy.
Transmission Input Speed Sensor – Aston Martin Vanquish ASM
This sensor provides the speed signal of the transmission input shaft. The speed signal is required by the control unit to control the transmission system, adjusting properly the shaft speeds before engaging and disengaging the different gears.
