Direction of rotation versus
flow
NOTE: The V12, V14 and T12 motors are
bi-directional.
V12 rotation:
- End cap position T (AC, AD and AH
controls): When port B (open arrow) is
pressurized, the motor rotates clockwise
(right hand; R), and when port A (black
arrow) is pressurized, the motor turns
counter clockwise (left hand; L)
- End cap position M (EO, EP, HO and
HP controls): A and B port positions inter-
change (A-to-B, B-to-A).
V14 rotation:
- Refer to the V14 illustration below right
(valid for all compensators and controls).
T12 rotation:
- Refer to the V14 illustration below right.
NOTE: Before installing a V12, V14 or
T12 motor in series (when both
A and B ports can be subject to
high pressures simultaneously)
contact Parker Hannifin.

Filtration
Maximum motor sevice life is obtained when the fluid cleanlineness meets or exceeds ISO
code 20/18/13 (ISO 4406).
A 10 µm (absolute) filter is recommended.
Case pressure
To secure correct case pressure and lubrication, a spring loaded check valve, 1-3
bar, in the drain line (shown on next page) is recommended.
NOTE: Contact Parker Hannifin for information when operating at high speeds.
Min and max case pressure [bar] vs. shaft speed [rpm].

Required inlet pressure
The motor may operate 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 condi-
tions.
Contact Parker Hannifin 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 requires case flushing in order for the
fluid to stay above the minimum viscosity requirement. A flushing valve and restricting noz-
zle, available as an option, provide the necessary main circuit flushing flow.

Drain ports
There are two drain ports on the V12 and T12 and three on the V14motors. The uppermost
drain port should always be utilized.
In order to avoid excessively high case pressure, the drain line should be connected di-
rectly to the reservoir.

Installation and start-up information
Hydraulic fluids
Ratings and performance data for the 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 trans-mission fluids type A, or API CD
engine oils can be used.
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 motor is 15 to 30 mm2/s.
Fire resistant fluids, when used under modified opera-ting conditions, and synthetic fluids
are also suitable.
Contact Parker Hannifin for additional information about:
- Hydraulic fluid specifications
- Fire resistant fluids.
Before start-up
Make sure the motor case as well as the entire hydraulic system is filled with hy-
draulic fluid.
The internal leakage, especially at low operating pressures, is not sufficient to provide lubri-
cation at start-up.

Running in procedure Parker Motors
We suggest the following procedure to run in the V12/V14/T12 motors.
1.Start @ 500 rpm, differential pressure 250 bar, outlet 10-15 bar.
2.Run until the drain temperature has passed its maximum* and has decreased 1-2 °C
3.Increase differential pressure to 350 bar
4.Run until the drain temperature has passed its maximum* and has decreased 1-2 °C
5.Increase differential pressure to 400 bar
6.Run until the drain temperature has passed its maximum* and has stabilized.
*If, at any point, the temperature tends to pass 100 °C, decrease the pressure at once.
Please make sure the drain temperature probe is in the drain oil flow to measure the
correct temp.
