Filtration Requirements:
• A filter of, at least, 25 micron filtration is required. A filter capable of 10 micron
filtration is preferred. The majority of paper type filters are 25 microns or better.
• A low pressure type filter can be installed in the return line from the control valves to
the sump. A low pressure type filter can, also, be installed in the sump or pump intake
line, but must be sized large enough to avoid starving the pump.
• A high pressure type filter can be used between the pump and the control valves.
• If the source of the hydraulic power does not have a filter, it will be necessary to install
one at some point in the system so, at least, part of the hydraulic oil is being filtered
whenever the system is operating. After a filter is installed and before attaching the
drive unit, the entire hydraulic system should be drained, filled with new oil, and
operated for 30 minutes or until the system is warm. During this run time, operate all
valves, cylinders, and hydraulic motors on the machine.
Pressure and Flow Requirements:
• Models 2545H and 3060H are designed to operate within the pressure range of 1500 to
3000 PSI. Models HP-2545H and HP-3060H are within 1500 to 5000 PSI.
• The hydraulic back pressure must not exceed 400 PSI.
• Operating flow rate is dependent on model: 25 to 45 GPM for Models 2545H and
HP-2545H and 30 to 60 GPM for Models 3060H and HP-3060H.
Valve Requirements:
• The hydraulic system used to power the drive unit should be equipped with a four-way
valve large enough to carry full pump outlet without restricting flow and causing oil
heating.
• The four-way valve requires a relief valve which will open and relieve extreme
pressures between the drive unit and control valve, even when the control valve is in a
neutral position. This feature can be obtained by connecting two external relief valves
between the main lines running from the control valve to the drive unit in such a way
that high pressure in either line will be relieved to the other line.
Hydraulic Hose Requirements:
• High pressure hoses of, at least, 3/4 inch inside diameter connect four-way valve to the
two ports on the drive unit.
• Working pressure of hydraulic hoses must be higher than the rated vehicle hydraulic
pressure.
• An abrasion sleeve is recommended on all hydraulic hoses.
• The motor ports are 3/4 inch (1-1/16" 12) SAE o-ring boss threads. The drive units for
Models 2545H and 3060H are shipped with female #12 JIC fittings installed in the
motor ports. The drive units for Models HP-2545H and HP-3060H are shipped with
female #12 o-ring face seal fittings installed in the motor ports.
• Since the motor is reversible, hose connections to motor fittings are interchangeable.
• All hoses, pipes, and fittings used to connect the drive unit should be thoroughly
cleaned before use. Care should be taken to see that no thread sealer or metal chips are
forced to the inside of the joints when connections are being tightened.
Hydraulic Fluid Selection Requirements:
• Premium grade petroleum based fluids will provide the best performance.
• Motor manufacturers recommend fluids that contains anti-wear agents, rust inhibitors,
anti-foaming agents, and oxidation inhibitors.
• The viscosity of the fluid should never fall below 70 SUS (13 cST). The best
viscosity range of the drive unit is 100-200 SUS (20-43 cST). 7
Hydraulic
Requirements
The life of the hydraulic motor is almost entirely dependent upon cleanliness of
the oil. Instructions in your vehicle operator’s manual regarding filter and oil
changes should be carefully followed. Even small amounts of dirt in the
hydraulic oil can cause premature motor failure that is not covered by warranty.
Excessive back pressure will result in hydraulic motor failure. If the hydraulic
back pressure exceeds 400 PSI, a case drain line must be installed.
