General information
Series V14 is a new generation of variable displacement
motors developed and manufactured by Parker Hanni-
fin, Pump and Motor Division.
The V14 is a further development of our well known V12
motor. It is designed for both open and closed circuits,
intended particularly for mobile applications.
New features:
• Increased shaft speeds
• Improved sealing
• Faster control response
• Improved shaft support
• Additional integrated functions
added
• New control, HPC, for winch
...mainly thanks to:
• Re-designed piston
• O-ring seals between housings
• Enlarged setting piston
• Increased size control device
• Tapered roller bearings
Important features carried over from
previous motors:
• Operating pressures to 480 bar
• High speeds, thanks to low weight pistons with lami-
nated piston rings and a very compact design of
therotating parts.
• High overall eciency throughout the entire
displacement range
• 9 pistons provide high start-up
torque and smooth operation
• Wide displacement range – 5:1
• Small envelope size and high power-to-weight ratio
• Low noise levels due to the compact, sturdy design
and smooth fluid passages
• Positive piston locking, strongsynchronizing shaft,
heavy-duty
bearings and a small number of parts add up to a
very robust motor with long service life and proven
reliability.

Installation
Motor installation
Direction of rotation
The V14 motor is bi-directional. Fig. 1 shows shaft rota-
tion vs. direction of flow.
When the A port is pressurized (black arrow) the mo-
tor turns counter clockwise (left hand, L, rotation), and
when the B port is pressurized (open arrow) the shaft
turns clockwise (right hand, R, rotation).
Note: Before installing the V14 in series (when the
A and B ports can be subject to high pressures
simultaneously) contact Parker Hannifin (Pump
& Motor Div.).
Filtration
Maximum motor service life is obtained when the fluid
cleanliness meets or exceeds ISO code 20/18/13 (ISO
4406).
A 10 μm (absolute) filter is recommended.
Case pressure
The lowest and highest recommended case pressure
(V14 with shaft seal type V) at selected shaft speeds is
shown in the table below.
The min case pressure secures sucient lubrication,
and the max case pressure, which secures nominal seal
life, should be measured at the drain port.
Fig. 1 (motor rotation vs. direction of flow).
Required inlet pressure
The motor operates as a pump under certain condi-
tions. When this occurs, a minimum pressure must be
maintained at the inlet port. Increased noise and gra-
dually deteriorating performance due to cavitation may
otherwise be experienced.
A 15 bar inlet pressure, measured at the motor inlet
port, satisfies most operating conditions.
Contact Parker Hannifin (Pump & Motor Div.) for more
specific information on inlet pressure requirements
Note: For high speed info, see Marketing information
database
Operating temperatures
The following temperatures should not be exceeded,
FPM shaft seal (type V) can be used to 115°C drain fluid
temperature.
Continuous operation at high power levels usually re-
quires case flushing in order for the fluid to stay above
the minimum viscosity requirements.
A flushing valve and restricting nozzle, available as an
option, provide the necessary main circuit flushing flow.

Drain ports
There are two drain ports on the V14; the uppermost
drain port should always be utilized (fig. 3).
In order to avoid excessively high case pressure, the
drain line should be connected directly to the reservoir.
Note: When the motor is operating, the case must be
filled with fluid to at least 50%.
Hydraulic fluids
Ratings and performance data for series V14 motors
are valid when a good quality, contamination-free, pet-
roleum-based fluid is used in the hydraulic system.
Hydraulic fluids type HLP (DIN 51524), automatic trans-
mission fluids type A, or API CD engine oils can be used.
Fire resistant fluids, when used under modified opera-
ting conditions, and synthetic fluids are also suitable.
When the hydraulic system has reached full operating
temperature, the motor drain oil viscosity should be
above 8 mm²/s (cSt).
At start-up, the viscosity should not exceed 1500 mm²/s.
The ideal operating range for the V14 series is 15 to 30
mm²/s.
The following information (available from Parker Han-
nifin, Pump & Motor Div.) provide additional information
about:
- Hydraulic fluid specifications
- Fire resistant fluids
Before start-up
Make sure the motor case as well as the entire hydrau-
lic system is filled with hydraulic fluid. The internal lea-
kage, especially at low operating pressures, is not suf-
ficient to provide lubrication at start-up.
Note: A drain line spring loaded check valve (shown
in fig. 2, 3 and 4) may have to be installed in or-
der to prevent oil from being siphoned out of the
motor case. This can otherwise happen e.g. if
the reservoir is located below the utilized motor
drain port.

Controls and gauge ports
Controls
The following controls satisfy most application require-
ments:
• AC (automatic pressure compensator)
• AH (automatic pressure compensator with hydraulic
override)
• EO and HO (two position controls)
• EP and HP (proportional controls)
All controls utilize a servo piston that connects to the
valve segment (refer to the illustration on page 4).
The built-in four-way servo valve determinesthe posi-
tion of the servo piston and, in turn,the displacement.
The displacement angle (between output shaft and cy-
linder barrel) ranges from 35° (max) to 6.5° (min).
Servo supply pressure is obtained from the pressuri-
zed, main port through the corres-ponding, built-in
shuttle valve.
The respons time (i.e. from max-to-min or from min-to-
max displacement) is determined by restrictors in the
servo valve supply and return lines; refer to the sche-
matics.

Pressure setting procedure
The pressure setting procedure is valid for all pressure
compensators (AC and AH).
1. Make sure that the motor has beensupplied with the
correct modulatingspring (ordering code and name
plate information should correspond).
2. Install 0 – 600 bar (0 – 8500 psi) gauges in port X1
and X5; refer tofig. 1.
3. Turn the adjustment screw counterclockwise to en-
sure that the threshold spring is unloaded. The dis-
tance between nut and screw end is approximately
23 mm when the threshold spring is unloaded.
Note: The distance between nut and screw end should
not be more than 28 mm, because of risk for
loosing guiding of the spring.
4. Increase the system pressure (e.g. by blocking the
motor shaft) to desired pressure setting (read the
pressure in port X5).
5. Start to turn the threshold adjustmentscrew clock-
wise until the pressure ingauge X2 starts to increase.
Rightthreshold pressure setting has beenreached.
Note: One turn of the setting screw corresponds to
57 bar (820 psi)
WARNING
In order to prevent injury to the technician or the
bystanders during the adjustment procedure, all
hydraulic functions on the vehicle/machine should
be disabled (e.g. wheels raised o the ground, work
functions disconnected).
Avoid fast forward/reversed changes that can
damage the synchronizing shaft.

(solenoid current increasing)
Refer to the illustration below left:
At an increasing current (above the threshold value),
the solenoid spool pushes left on the servo valve spool,
and flow is directed to the left hand setting chamber -
the setting spool moves to the right and the displace-
ment decreases.
This means, that the shaft speed increases while the
output torque decreases correspon-dingly (at a con-
stant pump flow and system pressure).
HP control function
(decreasing pilot pressure)
Refer to the illustration below right:
When the pilot pressure decreases, the pilot piston re-
tracts, the servo valve spool moves to the right and flow
is directed to the right hand setting chamber - the set-
ting spool moves to the left and the displacement in-
creases.
The shaft speed now decreases and the available out-
put torque increases corres-pondingly (at a constant

The pressure/current setting procedure is valid for all
proportional and two-position controls (EO, EP, HO and
HP).
1. Make sure that the motor has beensupplied with the
correct modulatingspring (ordering code and na-
meplateinformation should agree). The hydraulicoil
should be 50°C (120°F).
2. Install 0 – 600 bar (0 – 8500 psi) gaugein port X2.
Use a 0 – 60 bar (0 – 850 psi) gauge tomeasure pilot
pressure if it is a HO or HP.
3. Turn the adjustment screw counterclockwise to en-
sure that the threshold spring isunloaded. The dis-
tance between nut and screwend is approximately
22 mm when the thresholdspring is unloaded.
Note: If you remove solenoid or end cover the maxi-
mum distance between nut and screw end
should not be more then 16 mm. If the unit is
assembled the maximum distance between nut
and screw end should not be more then 22 mm.
HO or HP controls
4. Pressurize port X5 to desired threshold (thecontrol
goes to min displ.). Standard factory setting is 10
bar.Optional setting is 5 – 25 bar.
EO or EP controls
4. Apply the desired threshold current to the solenoid
(the control goes to min displ.).
Standard factory setting is
400 mA (12 VDC)
200 mA (24 VDC)
5. Start to turn the threshold adjustmentscrew clock-
wise until the pressure ingauge X1 starts to increase.
Rightthreshold pressure setting has beenreached.
Note: One turn of the setting screw corresponds to:
•40 mA on 12 VDC solenoids (EO, EP)
•20 mA on 24 VDC solenoids (EO, EP)
•2,1 bar (30 psi) on HO and HP controls
WARNING
In order to prevent injury to the technician or the
bystanders during the adjustment procedure, all
hydraulic functions on the vehicle/machine should
be disabled (e.g. wheels raised o the ground, work
functions disconnected).
Avoid fast forward/reversed changes that can
damage the synchronizing shaft.

HPC/EPC, HP/EP control with pressure
cut off
The pressure cut o overlays the
HP control.
- If the system pressure increase, due to the load or
reduced motor displacement, to the setting of the
pressure cut o valve, the control increases displa-
cement. When displacement increases, the available
torque increases as well but the system pressure re-
mains constant.
- Pressure cut o range is 100 – 400 bar (1450 –
5800 psi)
- Threshold pressure is preset from factory to 10 bar
(145 psi) but is adjustable between 5 and 50 bar
(70 – 700 psi).
- Threshold current is preset from factory to 400 mA
(12V) or 200 mA (24V).
12V is adjustable between 200-500 mA
24V is adustable between 100-250 mA
Cut off pressure setting procedure:
Untie the locking nut. One turn of the setting screw
corresponds to 48 bar. When desired pressure level is
reached, tighten the locking nut.
1. Install 0 – 600 bar (0 – 8500 psi) gauges in port X1
and X4 and a 0 – 60 bar (0 – 850 psi) gauge in port
X5.
2. Set the cut o pressure to minimum by turning the-
setting screw counter-clockwise until a distinct stop
isreached.
3. Set the motor displacement to minimum by apply-
ingrequired pressure to port X5.
4. Increase the pressure in one of the main ports A/B
(e.g. byblocking the motor shaft) to desired cut o
pressure level.
5. Turn the setting screw clockwise, until the pressure
inport X1 reaches the same pressure level as in X4.
Desired cut o pressure has been reached.

should have to obtain a chosen displacement is shown
on page 5 and 6. The displacement spacers are availa-
ble in five dierent lengths: 1; 1,5; 2; 5 and 10 mm. To
obtain the right displacement, the spacers can be com-
bined with each other’s. The thinnest spacer has to be
mounted closest to the setting piston, and the others in
increasing length order.
