We started off buying the console from BJ Hydraulics then everything else we custom made

Mechanical Neutral Adjustment Mechanical neutral is set with the pump running at 1800 min-1(rpm). To set neutral, you must stroke the pump in each direction. The procedure is the same for each side of each pump for both the front and rear sections. You can do this with a small movement of the eccentric screw on EDC controls, however non-feedback controls (NFPE/FNR) lack this mechanism. To stroke a pump with non-feedback control, you must provide a 100 Hz PWM signal to the control solenoids. If you perform this adjustment with the pump installed in a vehicle or machine, safely elevate the wheels or disconnect the mechanism to allow safe operation during adjustment. This procedure details setting neutral for the entire pump, one side at a time. Alternate M4/M5 and MA/MB to zero out forward and reverse directions of the front unit, then move the gauges to M4/M5 of the rear unit and MC/MD (system gauge ports for the rear unit). Refer to the drawing on the next page to identify all ports. The front and rear sections are basically mirror images of each other. The control solenoids C1 and C2 are marked on each control. While performing this adjustment, you monitor the following pressures: • Servo pressure at M4 and M5 • System pressure at MA and MB or MC and MD • Pressure differential between M4 and M5 (optional) • Pressure differential between A and B or MC and MD (optional) Unintended Machine Movement Unintended movement of the machine or mechanism may cause injury to the technician or bystanders. Secure the machine or disable/disconnect the mechanism while servicing to protect against unintended movement. Pump setup 1. Attach a 50 bar [1000 psi] gauge to each servo pressure port M4 and M5. 2. Attach a 600 bar [10 000 psi] gauge to each system pressure port (MA and MB for front pump, MC and MD for rear pump). 3. Remove servo cylinder locking screws (E350) and plates (E300) from both sides of the pump. 4. Disconnect the control solenoids from the vehicle wiring harness. 5. If using a PWM signal to set mechanical neutral, connect the control solenoids C1 and C2 to the signal source. Ensure the source supplies no current to the solenoids until required in the following procedure.
