General information
Series V16 is a new generation of variable displace-
ment, bent-axis motors. A further development of our
well known V12 and V14 motor series.
The new motor series is available in sizes 220 cc/rev
and 270 cc/rev.
It is designed for both open and closed circuit transmis-
sions with focus on high performance machines.
New features:
• Zero displacement capability
• Increased operating pressure, up to 550 bar
• Accurate control response
• Easy installation
...mainly thanks to:
• New motor design
• New design and simulation tools
• Best in class displacement range - 5.5:1
• Position sensor and plug in speed sensor available
together with a a flexible main port design
Important features carried over from
previous motors:
• High speeds, thanks to low weight pistons with lami-
nated piston rings and a very compact design of
the rotating parts.
• High overall eciency throughout the entire
displacement range
• 9 pistons provide high start-up torque and smooth
operation
• 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.

V16 Displacement limiter
Max and min displacement limiter consists of a hex
socket screw and stop washers or spacers, see fig. 1.
Suitable screw lengths for a particular max or min dis-
placement range are shown on page 7-10. What length
the max or min displacement spacer should have to ob-
tain a chosen displacement is shown on pages 7-10.
The displacement spacers are available in five dierent
lengths: 1; 1.5; 2; 5 and 10 mm. To obtain the right dis-
placement, 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.
Displacement limiter
Displacement spacer changing
procedure:
1. Disassemble the max and/or min end cover/control
cover by loosening the screws for the chosen cover.
2. Loosen the socket head cap screw from setting pis-
ton.
Note: This must be done when the end cap is as-
sembled on the motor, otherwise the feedback arm
could be damaged.
3. Choose spacer (s) to obtain right displacement, see
page 7 - 10, and place them on the socket head cap
screw.
4. Tighten the socket head cap screw in the setting pis-
ton. The tightening torque is 114 ± 10 Nm.
5. Assembly the end cover / control cover. The tighte-
ning torque is 114 ± 10 Nm for the screws.

Motor installation
Direction of rotation
The V16 motor is bi-directional. Fig. 1 shows shaft rota-
tion vs. A or B port pressurized.
With inlet flow at port A the shaft turns counter clock-
wise (left hand, L, rotation), and with inlet flow at port B
the shaft turns clockwise (right hand, R, rotation).
Note: Before installing the V16 in series (when the
A and B ports can be subject to high pressures
simultaneously) contact Parker Hannifin (Pump
& Motor Division Europe).
Filtration
Maximum motor service life is obtained when the flu-
id 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 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. A or B port pressurized).
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 20 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
Operating temperatures
The following temperatures should not be exceeded,
Main circuit: 80°C
Drain fluid: 115°C
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.
Refer to fig. 2 (next page).

Drain ports
There are two drain ports on the V16; 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 V16 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 V16 series is 15 to 30
mm²/s.
The following information (available from Parker Han-
nifin, Pump & Motor Division Europe) 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
AC control function
Refer to the catalogue MSG30-8223/UK.
Scan QR code below.
The following controls satisfy most application require-
ments:
• AC (automatic pressure compensator)
• EO and HO (two position controls)
• EP and HP (proportional controls)
• HPC/EPA/EPB (HP/EP control with pressure cut o)
• HOC/EOA/EOB (HO/EO control with pressure cut
o)
All controls utilize a servo piston that connects to the
valve segment.
The built-in three-way servo valve determines the 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° (min).
Internal servo supply pressure is obtained from the
pressurized main port through a built-in shuttle valve.
The respons time (i.e. from max-to-min or from min-to-
max displacement) is determined by restrictor nozzles
in the servo valve supply and return lines; refer to the
schematics in catalogue MSG30-8223/UK.

Threshold setting procedure
AC with positive control characteristics (T code)
With motor not pressurized (ACI control type) or with
port X5 (ACE control type) not pressurized, the motor
will be kept at minimum displacement.
1. Make sure that the motor has been supplied with the
correct modulating spring (ordering code and name
plate information should agree). The hydraulic oil
should be 50°C.
2. Install a 0 – 600 bar gauge in port X1 and X5.
3. Turn the adjustment screw counter clockwise to en-
sure that the threshold spring is unloaded.
4. Pressurize the motor (ACI control type) and port X5
for ACE control type to desired threshold pressure
(at this pressure the control starts to go to max. dis-
placement).
5. Start turn the threshold adjustment screw clockwi-
se until the pressure gauge in port X1 starts to de-
crease. Right threshold pressure has been reached.
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.
