4 Introduction Variable displacement piston pumps are used in closed loop systems either as a single or tandem pump. Oil is circulated by the pump to the motor and then returned directly back to the pump. charge supply is used to supplement the closed loop system with oil. The charge supply may be supplied by an internal charge pump (standard) or an external source.

The EP displacement control provides the flexibility of three command input choices. Control components include a proportional solenoid actuated valve assembly and an electronic solenoid driver module mounted on the pump. The control driver module converts a command input signal to a proportional current output to the proportional solenoids resulting in a proportional pump displacement. The EP displacement control has been designed to withstand the rigors of off-highway equipment environmental conditions.

Note: In order to assure the most reliable installation and operation of any electronic control, proper installation methods should be followed with respect to interconnection wiring harness, command signal devices, fusing, and input power switching. Proper care should be taken to prevent damage to all electrical and electronic components due to abrasion, moving objects, heat, moisture or other environmental hazards. For safety critical applications, Eaton recommends that a switch be installed in line with (+ Battery) power to the module so that power may quickly be disconnected in case of emergency. 2 ampere slow blow fuse should always be installed in the + battery line. It is recommended that during initial start-up and checkout, the machine be placed on jack stands to prevent inadvertent movement of the machine.

64 pplication Info. Component Selection The long service life of Eaton hydrostatic transmissions is largely dependent on the proper selection and installation of the components necessary for transmission operation. The following components are necessary for transmission operation: 1. Variable Displacement Pump 2. Fixed or Variable Displacement Motor. Reservoir 4. Filter 5. Charge Pump Inlet Line 6. Pump and Motor Case Drain Lines 7. High Pressure Lines 8. Heat Exchanger 9. Heat Exchanger Bypass Valve 10. Reservoir Return Line 1. Variable Displacement Pump Eaton hydrostatic variable displacement pumps are an axial piston design. They are equipped with standard SE mounts, shafts and port connections. 2. Fixed or Variable Displacement Motor Eaton hydrostatic motors are an axial piston design. They are equipped with standard SE mounts, shafts and port connections.. Reservoir The reservoir is an important part of the hydrostatic transmission system. It should provide adequate oil storage and allow easy oil maintenance. The reservoir must hold enough oil to provide a continuous oil supply to the charge pump inlet. It must also have enough room for the hydraulic oil to expand as the system warms up. Consider charge pump flow when sizing the reservoir: One half (.5) minute times (X) the maximum charge pump flow should be the minimum oil volume in the reservoir. Maintaining this oil volume will give the oil a minimum of thirty (0) seconds in the reservoir. This will allow any entrained air to escape and contamination to settle out of the oil. To allow for oil expansion, the reservoir s total volume should be at least six tenths (.6) minute times (X) the maximum charge pump flow. The reservoir s internal structure should cut down turbulence and prevent oil aeration. The line returning flow to the reservoir should be fitted with a diffuser to slow the incoming oil to 1 to 1.2 meters [-4 feet] per second to help reduce turbulence. The return flow line should also be positioned so that returning oil enters the reservoir below the liquid surface. This will help reduce aeration and foaming of the oil. The reservoir should have baffles between the return line and suction line. Baffles prevent return flow from immediately reentering the pump. sixty mesh screen placed across the suction chamber of the reservoir will act as a bubble separator. The screen should be placed at a 0 angle to the horizon. The entrance to the suction line should be located well below the fluid surface so there is no chance of air being drawn into the charge pump inlet. However, the suction line entrance should not be located on the bottom of the reservoir where there may be a buildup of sediment. The suction line entrance should be flared and covered with a screen. The reservoir should be easily accessible. The fill port should be designed to minimize the possibility of contamination during filling and to help prevent over filling. There should be a drain plug at the lowest point of the reservoir and it should also have a clean-out and inspection cover so the reservoir can be thoroughly cleaned after prolonged use. vented reservoir should have a breather cap with a micronic filter. Sealed reservoirs must be used at altitudes above 2500 feet. These reservoirs should be fitted with a two- way micronic filter pressure cap to allow for fluid expansion and contraction. In both cases the caps must be designed to prevent water from entering the reservoir during bad weather or machine washing. hydrostatic transmission with a well designed reservoir will run quieter, stay cleaner and last longer. 4. Filter filter must be used to keep the hydraulic fluid clean. Either a suction filter or a pressure side filter may be used. The filter must be a no-bypass type. System oil particle levels should not exceed ISO 18/1. Refer to Eaton Hydraulic Fluid Recommendations. Recommended beta ratios for each filter type are listed below: Suction Filter ß 10 = 1.5 to 2.0 Pressure Side Filter ß 10 = 10 to 20 When a suction filter is used, its flow capacity must be large enough to prevent an excessive pressure drop between the reservoir and charge pump inlet. The pressure at the charge pump inlet port must not be less than 0,80 bar absolute [6 in. Hg.] at normal continuous operating temperatures. 5. Charge Pump Inlet Line The inlet line to the charge pump should be large enough to 64

Pump and Motor Case Drain The case drain lines should be large enough to limit the pump and motor case pressures (Medium Duty to 2 bar [25 PSI]) at normal operating temperatures. Fluid and temperature compatibility must also be considered when selecting the case drain lines. 7. High Pressure Lines The high pressure lines that connect the pump and motor must be able to withstand the pressures generated in the high pressure loop. drain port on each of the units. This assures that the pump and motor cases remain full. The combined torque required to turn two or more pumps must not exceed the torque rating of the input drive shaft of the front piston pump. Installer to provide centering and a secure neutral for pump swashplate control shaft. n external support is recommended for all tandems. For engines prone to higher torsional vibration, install a torsional vibration damper in the pump drive line. Open Loop Circuits Eaton pumps and motors may be used in open loop circuits under certain operating conditions. Consult your Eaton representative for details. 8. Heat Exchanger Use of a heat exchanger is dependent on the transmission s duty cycle and on machine layout. The normal continuous operating fluid temperature measured in the pump and motor cases should not exceed 80½C [180½F] for most hydraulic fluids. The maximum fluid temperature should not exceed 107½C [225½F]. The heat exchanger should be sized to dissipate 25% of the maximum input power available to the transmission. It must also be sized to prevent the case pressures in the pump and motor from getting too high. Medium duty case pressure up to 2 bar [25 psi], at normal operating temperatures, are acceptable. 9. Heat Exchanger Bypass Valve The heat exchanger bypass valve is a pressure and/or temperature valve in parallel with the heat exchanger. Its purpose is to prevent case pressures from getting too high. The heat exchanger bypass valve opens when the oil is thick, especially during cold starts. 10. Reservoir Return Line The same general requirements that apply to case drain lines apply to the reservoir return line. Installation Requirements The mounting orientation of pumps and motors is unrestricted provided the case drain of the pump and motor remain full. Position the case drain such that it assures an oil level at or above unit center line at start-up. The case drain line that carries the flow leaving the pump or motor should be connected to the highest 65

66 pplication Info. Hydraulic Fluid Recommendations Introduction The ability of Eaton hydrostatic components to provide the desired performance and life expectancy depends largely on the fluid used. The purpose of this document is to provide readers with the knowledge required to select the appropriate fluids for use in systems that employ Eaton hydrostatic components. One of the most important characteristics to consider when choosing a fluid to be used in a hydraulic system is viscosity. Viscosity choice is always a compromise; the fluid must be thin enough to flow easily but thick enough to seal and maintain a lubricating film between bearing and sealing surfaces. Viscosity requirements for Eaton s Heavy Duty Hydrostatic product line are specified later in this document. Viscosity and Temperature Fluid temperature affects viscosity. In general, as the fluid warms it gets thinner and its viscosity decreases. The opposite is true when fluid cools. When choosing a fluid, it is important to consider the start-up and operating temperatures of the hydrostatic system. Generally, the fluid is thick when the hydraulic system is started. With movement, the fluid warms to a point where the cooling system begins to operate. From then on, the fluid is maintained at the temperature for which the hydrostatic system was designed. In actual applications this sequence varies; hydrostatic systems are used in many environments from very cold to very hot. Cooling systems also vary from very elaborate to very simple, so ambient temperature may affect operating temperature. Equipment manufacturers who use Eaton hydrostatic components in their products should anticipate temperature in their designs and make the appropriate fluid recommendations to their customers. In general, an ISO viscosity grade 68 fluid is recommended for operation in cold to moderate climates. n ISO viscosity grade 100 fluid is recommended for operation in moderate to hot climates. Cleanliness Cleanliness of the fluid in a hydrostatic system is extremely important. Eaton recommends that the fluid used in its hydrostatic components be maintained at ISO Cleanliness Code 18/1 per SE J1165. This code allows a maximum of 2500 particles per milliliter greater than 5 µm and a maximum of 80 particles per milliliter greater than 15 µm. When components with different cleanliness requirements are used in the same system, the cleanest standard should be applied. OEM s and distributors who use Eaton hydrostatic components in their products should provide for these requirements in their designs. reputable filter supplier can supply filter information. Fluid Maintenance Maintaining correct fluid viscosity and cleanliness level is essential for all hydrostatic systems. Since Eaton hydrostatic components are used in a wide variety of applications it is impossible for Eaton to publish a fluid maintenance schedule that would cover every situation. Field testing and monitoring are the only ways to get accurate measurements of system cleanliness. OEM s and distributors who use Eaton hydrostatic components should test and establish fluid maintenance schedules for their products. These maintenance schedules should be designed to meet the viscosity and cleanliness requirements laid out in this document. Fluid Selection Premium grade petroleum based hydraulic fluids will provide the best performance in Eaton hydrostatic components. These fluids typically contain additives that are beneficial to hydrostatic systems. Eaton recommends fluids that contain anti-wear agents, rust inhibitors, antifoaming agents, and oxidation inhibitors. Premium grade petroleum based hydraulic fluids carry an ISO VG rating. 66

Motor cavitation is not a problem during cold start-ups, except for two speed motors. Thick oil can cause high case pressures which in turn cause shaft seal problems. When choosing a hydraulic fluid, all the components in the system must be considered and the optimum viscosity range adjusted accordingly. For example, when a medium duty piston pump is combined with a Disk Valve Motor the optimum viscosity range becomes SUS [20-9 cst] and viscosity should never fall below 70 SUS [1 cst]. If the natural color of the fluid has become black it is possible that an overheating problem exists. If the fluid becomes milky, water contamination may be a problem. Take fluid level reading when the system is cold. Contact your Eaton representative if you have specific questions about the fluid requirements of Eaton hydraulic components. 67
