Hydraulic Motor/Pump Series V14
...mainly thanks to:
• Re-designed piston
• O-ring seals between housings
• Enlarged setting piston
• Increased size control device
• Tapered roller bearings
New features:
• Increased shaft speeds
• Improved sealing
• Faster control response
• Improved shaft support
• Additional integrated functions added
General information
Series V14 is a new generation of variable
displacement motors developed and
manufactured by Parker Hannifin, Mobile
Controls 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 efficiency 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 fluid
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

Hydraulic Motor/Pump Series V14
Motor installation
Direction of rotation
The V14 motor is bi-directional. Fig. 1 shows
shaft rotation vs. direction of flow.
When the A port is pressurized (black arrow)
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 Parker Hannifin (Mobile Controls Div.).
Filtration
Maximum motor service life is obtained when
the fluid cleanliness meets or exceeds ISO
code 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 H) at
selected shaft speeds is shown in the table
below.
The min case pressure secures sufficient
lubrication, and the max case pressure,
which secures nominal seal life, should be
measured at the drain port.
Note: Contact Parker Hannifin (Mobile
Controls 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, satisfies most operating
conditions.
Contact Parker Hannifin (Mobile Controls
Div.) for more specific information on inlet
pressure requirements.
Operating temperatures
The following temperatures should not be
exceeded (type H shaft seal):
Main circuit: 80 °C
Drain fluid: 100 °C
FPM shaft seals (type V) can be used to
115 °C drain fluid temperature.
Continuous operation at high power levels
usually requires 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.
Refer to fig. 2 (next page).

Hydraulic Motor/Pump Series V14
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, petroleum-based fluid is
used in the hydraulic system.
Hydraulic fluids type HLP (DIN 51524),
automatic transmission fluids type A, or
API CD engine oils can be used.
Fire resistant fluids, when used under
modified operating 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 publications (available from
Parker Hannifin, Mobile controls Div.) provide
additional information:
MI 180 - Hydraulic fluid specifications
MI 189 - Fire resistant fluids
Before start-up
Make sure the motor case as well as the
entire hydraulic system is filled with hydraulic
fluid. The internal leakage, especially at low
operating pressures, is not sufficient 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 order 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.

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
connects 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 corresponding, 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.

AC control function
Refer to the illustration below left:
When pressure in port A (or B) increases, the
servo valve spool is pushed to the right,
directing flow to the right hand setting
chamber - the setting spool moves to the left;
displacement and output torque increases. At
the same time, the shaft speed decreases
correspondingly (at a constant pump flow to
the motor).
AC control function (displ. increase at increasing
pressure).

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 fig. 1.
3. Turn the adjustment screw counter
clockwise to ensure that the threshold
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 desired
pressure setting (read the pressure 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.
fig. 1
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 57 bar (820 psi).
