General information
Series V14 is a new generation of variable
displacement motors developed and ma-
nufactured by Parker Hannin, 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.
Important features carried over
from previous motors:
• Operating pressures to 480 bar
• High speeds, thanks to low weight
pistons with laminated piston rings
and a very compact design of the
rotating parts.
• High overall efciency throughout the
entire displacement range
• 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 uid
passages
• Positive piston locking, strong
synchronizing shaft, heavy-duty
bearings and a small number
of parts add up to a very robust
motor with long service life and
proven reliability.
• 9 pistons provide high start-up
torque and smooth operation

Motor installation
Direction of rotation
The V14 motor is bi-directional. Fig. 1
shows shaft rotation vs. direction of ow.
When the A port is pressurized (black ar-
row) the motor 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 Par-
ker Hannin (Mobile Controls Div.).
Filtration
Maximum motor service life is obtained
when the uid cleanliness meets or exceeds ISO code 18/13 (ISO 4406).
A 10 µm (absolute) lter is recommended.
Case pressure
The lowest and highest recommended case
pressure (V14 with shaft seal type H or V)
at selected shaft speeds is shown in the
table below.
The min case pressure secures sufcient
lubrication, and the max case pressure,
which secures nominal seal life, should be
measured at the drain port.
Note: Contact Parker Hannin (Pump and
Motor Div.) for information on other shaft
seals.

Required inlet pressure
The motor operates as a pump under certain conditions. When this occurs, a minimum pressure must be maintained at the
inlet port. Increased noise and gradually
deteriorating performance due to cavitation
may otherwise be experienced.
A 15 bar inlet pressure, measured at the
motor inlet port, satises most operating
conditions.
Contact Parker Hannin (Mobile Controls
Div.) for more specic information on inlet
pressure requirements.
Operating temperatures
The following temperatures should not be
exceeded (type H shaft seal):
Main circuit: 80 °C
Drain uid: 100 °C
FPM shaft seals (type V) can be used to
115 °C drain uid temperature.
Continuous operation at high power levels
usually requires case ushing in order for
the uid to stay above the minimum visco-
sity requirements.
A ushing valve and restricting nozzle, available as an option, provide the necessary
main circuit ushing ow.
Refer to g. 2 (next page).

Drain ports
There are two drain ports on the V14; the
uppermost drain port should always be
utilized (g. 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 lled with uid to at least
50%.
Hydraulic uids
Ratings and performance data for series
V14 motors are valid when a good quality,
contamination-free, petroleum-based uid is
used in the hydraulic system.
Hydraulic uids type HLP (DIN 51524),
automatic transmission uids type A, or API
CD engine oils can be used.
Fire resistant uids, when used under modied operating conditions, and synthetic
uids 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 Hannin, Pump and Motor Div.) provide additional information about:
- Hydraulic uid specications
- Fire resistant uids
Before start-up
Make sure the motor case as well as the
entire hydraulic system is lled with hydraulic uid. The internal leakage, especially at
low operating pressures, is not sufcient to
provide lubrication at start-up.
Note:
A drain line spring loaded check valve (shown in
g. 2, 3 and 4) may have to be installed in order to
prevent oil from being siphoned out of the motor
case. This can otherwise happen e.g. if the reser-
voir is located below the utilized motor drain port.

AC control module cross section (as seen from motor
intermediate housing / control module interface).
The following controls satisfy most application
requirements:
• AC (automatic pressure compensator)
• AD (Automatic pressure compensator with
electric override and brake defeat)
• 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 con-
nects to the valve segment (refer to the illustration on page 4).
The built-in four-way servo valve determines
the position of the servo piston and, in turn,
the displacement.
The displacement angle (between output
shaft and cylinder barrel) ranges from 35°
(max) to 6.5° (min).
Servo supply pressure is obtained from the
pressurized, 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 schematics.
* Yellow seal cap is factory mounted. Red seal cap is available as spare part, part no. 3797065.

Pressure setting procedure
The pressure setting procedure is valid for
all pressure compensators (AC, AD and
AH).
1. Make sure that the motor has been
supplied with the correct modulating
spring (ordering code and name
plate information should correspond).
2. Install 0 - 600 bar (0 - 8500 psi)
gauges in port X1 and X5; refer to
g. 1.
3. Turn the adjustment screw counter
clockwise to ensure that the thres hold spring is unloaded.
The distance 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 desi
red pressure setting (read the pres
sure in port X5).
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 off the ground, work functions
disconnected).
Avoid fast forward/reversed changes that
can damage the synchronizing shaft.
g. 1
5. Start to turn the threshold adjustment
screw clockwise until the pressure in
gauge X2 starts to increase. Right
threshold pressure setting has been
reached.
Note: One turn of the setting screw corresponds to 57 bar (820 psi).

EO/EP/HO/HP control description
Basically, the controls function in a similar
way. At increasing solenoid current (EP) or
increasing pilot pressure (HP) the control
moves towards the min displacement position. At decreasing current/pilot pressure,
the control retracts towards max displacement.
In comparison with EP and HP, the EO and
HO controls have no modulating spring or
feedback arm; this means that only min and
max displacements (but no intermediate
positions) are available with these controls.

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 ow is directed to the
left hand setting chamber - the setting spool
moves to the right and the displacement decreases.
This means, that the shaft speed increases
while the output torque decreases correspon-

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 off the ground, work functions
disconnected).
Avoid fast forward/reversed changes that
can damage the synchronizing shaft.
Gauge ports EO/EP/HO/HP
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 been
supplied with the correct modulating
spring (ordering code and nameplate
information should agree). The hydraulic
oil should be 50°C (120°F).
2.Install 0 - 600 bar (0 - 8500 psi) gauge
in port X2. Use a 0 - 60 bar (0 - 850 psi) gauge to
measure pilot pressure if it is a HO or HP.
3.Turn the adjustment screw counter
clockwise to ensure that the threshold spring is
unloaded. The distance between nut and screw
end is approximately 22 mm when the threshold
spring is unloaded.
Note! If you remove solenoid or end cover the
maximum 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 (the
control goes to min displ.).
Standard factory setting is 10 bar.
Optional setting is 5 - 25 bar.

4.Apply the desired threshold current to the solenoid (the control goes to min displ.).
5. Start to turn the threshold adjustment
screw clockwise until the pressure in
gauge X1 starts to increase. Right
threshold pressure setting has been
reached.
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

HPC, HP control with pressure cut off
- The pressure cut off overlays the
HP control.
- If the system pressure increase, due
to the load or reduced motor displacement,
to the setting of the pressure cut off valve,
the control increases displacement.
When displacement increases, the available
torque increases as well but the system
pressure remains constant.
- Pressure cut off range is 75 - 400 bar
(1100 - 5800 psi)
- Threshold pressure is preset from factory
to 10 bar (145 psi) but is adjustable between
5 and 50 bar (70 - 700 psi).
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 off pressure to minimum by turning the
setting screw counter-clockwise until a distinct stop is
reached.
3. Set the motor displacement to minimum by applying
required pressure to port X5.
4. Increase the pressure in one of the main ports A/B (e.g. by
blocking the motor shaft) to desired cut off pressure level.
5. Turn the setting screw clockwise, until the pressure in
port X1 reaches the same pressure level as in X4.
Desired cut off pressure has been reached.

V14 Displacement limiter
Max and min displacement limiter consists of a socket head cap screw and a displacement
spacer or spacers, see g. 1. Suitable screw lengths for a particular max or min displacement
range are shown in the table 1 below.
Displacement spacer (s) [mm] Socket head cap screw Parker No.
0 - 24 M12 x 45 3785700
25 - 39 M12 x 60 3707695
40 - 60 M12 x 80 3782519
Table 1
What length the max or min displacement spacer should have to obtain a chosen displa-
cement is shown on page 5 and 6. The displacement spacers are available in ve different
lengths: 1; 1,5; 2; 5 and 10 mm. To obtain the right displacement, the spacers can be combined with each other’s. The thinnest spacer has to be mounted closest to the setting piston,
and the others in increasing length order.
Formula for determining the setting angle (a) at a selected displacement Da:
sin a = (Da/D35) * sin 35°
where: D35 is max displacement at 35°
Displacement spacer changing procedure:
1. Disassemble the max or min end cover by loosen
the four screws for the chosen cover.
2. Loosen the socket head cap screw from setting piston.
Note! This must be done when the control module is
assembled on the motor, otherwise the
feedback arm could be damaged.
3. Choose spacer (s) to obtain right displacement, see page 5 and 6, and place them
on the socket head cap screw.
4. Tighten the socket head cap screw in the setting piston. The tightening torque have
to be 105 ± 20 Nm.
5. Assembly the end cover. The tightening torque have to be 60 ± 10 Nm for the four
screws.

Test procedure
Use a test stand that supplies
a ow of about 30 l/min. and
pressures of up to 300 bar.
A secondary ow of 3-5
l/min. at a pressure of 25
bar is required to supply
low pressure for externally
supplied controls.
EP control requires an
amplier supplying correct
current according to
specication.
Test
1. Fill housing with hydraulic
uid and start the pump in the
test stand.
2. Increase the pressure
with the restrictor valve on
the return line. Max allowed
pressure is 150 bar / 2150 psi.
3. Check the drain ow and
compare with the table.
V14-110, -160
