Transit Mixers – System Applicatons
Major Components This guide is intended to provide an overview of a basic hydraulic system used on a typical Transit Mixer. Use of block diagrams will emphasize the relationship of Eaton components and how they can complement each other and be utilized to complete an efficient and cost effective hydraulic system. The Five Major Components of a Transit Mixer system are listed in the diagram below.
Eaton Heavy Duty Fixed Motor with Integral Shuttle Valve
Eaton Heavy Duty Variable Displancement Pump with Power Limiter Valve
Ready Mix Concrete
Mixer Drum
Gearbox
Power Source (engine)
The power source turns the variable displacement pump creating hydraulic pressure which controls the flow and causes the fixed motor to turn. The fixed motor then turns the gearbox which rotates the mixer drum at the desired speed.

Hydraulic Fluid Recommendations Introduction
Fluid Maintenance
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.
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.
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.
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 18/13 per SAE 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. A reputable filter supplier can supply filter information. 10
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. SAE grade crankcase oils may be used in systems that employ Eaton hydrostatic components, but it should be noted that these oils may not contain all of the recommended additives. This means using crankcase oils may increase fluid maintenance requirements. Hydraulic fluids that contain V.I. (viscosity index) improvers, sometimes called multi-viscosity oils, may be used in systems that employ Eaton hydrostatic components. These V.I. improved fluids are known to “shear-down” with use. This means that their actual viscosity drops below the rated value. Fluid maintenance must be increased if V.I. improved fluids are used. Automotive automatic transmission fluids contain V.I. improvers. Synthetic fluids may be used in Eaton hydrostatic components. A reputable fluid supplier can provide information on synthetic fluids. Review applications that require the use of synthetic fluids with your Eaton representative.

Additional Notes: • Fluids too thick to flow in cold weather start-ups will cause pump cavitation and possible damage. Motor cavitation is not a problem during cold start-ups. Thick oil can cause high case pressures which in turn cause shaft seal problems. • 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 hydrostatic components.

80% of normal pressure rating listed for mineral oils.
82° C (180° F) max fluid temp (unit) 71° C (160° F) max fluid temp (reservoir)
Additional Notes: • Viscosity and ISO cleanliness requirements must be maintained as outlined on previous page . • Based on limited product testing to date, no reduction in unit life is expected when operating at the pressure ratings indicated above. • Vegetable oil is miscible with mineral oil. However, only the vegetable oil content is biodegradable. Systems being
converted from mineral oil to vegetable oil should be repeatedly flushed with vegetable oil to ensure 100% biodegradability. • Specific vegetable oil products may provide normal unit life when operating at pressure ratings higher than those indicated above.

Note: To protect your instrumentation, all gauges should be dampened (or snubbed) and mounted with flexible lines.
Pressure Readings Nominal Operating Pressures The pressures given in this manual are gauge pressures or delta pressures. A pressure gauge reads zero when connected to atmospheric pressure. Any reading above or below this zero point is referred to as gauge pressure (bar [PSI]). Delta pressure is the difference of two gauge pressures in a hydraulic circuit. Example: Charge pressure reading of 16,5 bar [240 PSI] - Case pressure reading of 1,5 bar [20 PSI] Differential pressure of 15,0 D bar [220 D PSI] Typical hydrostatic circuits usually include a inlet pressure, case pressure, low or charge pressure and system or high pressure. These pressures will vary per each individual application and operating conditions.
(At Normal Operating Temperature) Inlet Vacuum:
Should not exceed 254 mm [10 in.] mercury (Hg.) for an extended period of time
Case pressure:
Should not exceed 2,8 bar [40 PSI] for an extended period of time
Charge Pressure:*
Neutral 15,2 D bar [220 DPSI] Forward or Reverse 11,0 D bar [160 DPSI]
*Charge Pressure Relief valves are factory preset to their nominal setting with a 7,6 l/min [2 GPM] flow rate. The original valve pressure will increase approximately, 45 bar per 3,8 l/min [6.5 PSI per 1 GPM] additional flow over the valve. The charge pressures given above are typical. Higher charge pressures may be set at the factory for your particular application. 13
