    START UP START UP PROCEDURE FOR NEW INSTALLATION • Read and understand the instruction manual. Identify components and their function. • Visually inspect components and lines for possible damage. • Check reservoir for cleanliness. Drain and clean as required • Check fluid level and fill as required with filtered fluid at least as clean as that recommended. Fill pump case with clean oil prior to starting.

  • Page 8: Trouble Shooting Charts

    TROUBLESHOOTING Component problems and circuit problems are often interrelated. An improper circuit may operate with apparent success but will cause failure of a particular component within it. The component failure is the effect, not the cause of the problem. This general guide is offered to help in locating and eliminating the cause of problems by studying their effects.

  • Page 25: Controls

    CONTROLS GENERAL The instructions contained in this manual cover complete disassembly and reassembly of the controls. Before pro- ceeding with the disassembly or reassembly of any unit, this manual should be studied in order to become familiar with proper order and parts nomenclature DESCRIPTION OF OPERATION A pilot operated valve spool and sleeve combination is the core of the control function.
  • Page 26 CONTROLS HYDRAULIC STROKER In the hydraulic stroker, a spring loaded piston is attached to the pin. A control pressure of 50 psi, 3,45 bar causes the piston to commence to move against the spring, to position the pin in proportion to the control pressure, and thus cause the pump to stroke in proportion to control pressure.

    TEST PROCEDURE compensator adjustment port “C1” differential adjustment vent “V” TEST CIRCUIT COMPENSATOR OVERRIDE CAP COMPENSATOR OVERRIDE ROTARY SERVO INPUT COMPENSATOR TEST Outlet relief valve should be set to minimum pressure. If the pump contains a servo, hydraulic or electrohydraulic stroker control, test that control first, (pg. 64, 68 or 69) then set the control to give full displacement on the pump.

  • Page 67: Load Sensing Test

    TEST PROCEDURE Raise compensator from minimum to maximum outlet pressure. At each condition, increase the outlet pressure until the pump fully de-strokes. At no time should the outlet pressure vary over 150 psi, 10,3 bar from the compensator set- ting. The control should be steady and stable at all conditions. Calculate compensator leakage by subtracting leakage flow at full flow from leakage flow fully compensated.

  • Page 70: Torque Limiter And Torque Limiter Override Test

    TEST PROCEDURE TORQUE LIMITER AND TORQUE LIMITER OVERRIDE TEST The torque limiter design is a compensator with a means of vary- ing pump displacement with pressure in this manner: The com- pensator vent port applies pressure to a pin. The pin moves against two independently adjustable springs.
  • Page 71 TEST PROCEDURE Set the compensator to 3000 psi, 207 bar, 6000 psi, 414 bar, and 7250 psi, 500 bar. (One turn approximately equals 2000 psi, 138 bar) At each condition, increase the outlet pressure until the pump fully de-strokes. At no time should the outlet pressure vary more than 150 psi, 10,3 bar from the compensator setting.

  • Page 72: Load Sensing Torque Limiter Test

    TEST PROCEDURE LOAD SENSING TORQUE LIMITER Caution: Load sensing control is limited to 5000 psi, 345 bar maximum pressure. Pump should be connected to speed control valve, load sensing line and load valve as shown. Install gages on outlet pressure and “V” capable of measuring pressure difference to 10 psi, 0,69 bar.
  • Page 73 TEST PROCEDURE Open load valve slowly, to drop outlet pressure toward minimum. Flow shall remain constant within 2 gpm, 7,6 lpm at all pressures. Adjust the speed control valve till flow is at a low value. Note flow. Raise and lower outlet pressure by closing and opening the load valve.
