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.
