HOSE-BULK 5342504 - Caterpillar

Enter the service mode on the monitor.
Input the password "9992".
Select "Override Parameters".
Override "Power Shift Pressure" to 2350 kPa (340 psi). Note: Confirm the power shift pressure setting at the pressure tap.
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings.
When "Power Shift Pressure" is highlighted, press OK key (C).
Illustration 12 g03678142
Once "Power Shift Pressure" is selected, press up key (F) or down key (G) in order to increase or decrease the numeric value that is displayed on the monitor display. Pressing down key (G) decreases the power shift pressure. Pressing up key (F) increases the power shift pressure. Refer to Illustration 11 for the monitor controls.
Set "Power Shift Pressure" to 2350 kPa (340 psi), then press OK key (C). Refer to Illustration 12.Note: The value for power shift pressure on the monitor may not always match the pressure reading on the pressure gauge. Adjust the value on the monitor until the desired power shift pressure is attained on the pressure gauge that is connected to the pressure tap for power shift pressure. The actual power shift pressure must be 2350 kPa (340 psi) on the pressure gauge.Note: To prevent a change in power shift pressure during the pump flow testing, do not exit the "Override Parameters" screen and do not turn the engine start switch to the OFF position.Note: Refer to System Operation, "Monitoring System" for additional information on Service Mode.
In order to perform flow measurements for either one of the pumps, the other pump must not be under load.

(1) Minimum FlowNote: Specifications for output flow rates are based on an engine speed of 1700 rpm. To attain more accurate test results, measured flow should be corrected with the following calculation.
Table 4
Corrected flow = Measured flow x 1700 rpm
measured rpm Note: Specifications for output flow rates are based on a power shift pressure at the pump of 2350 kPa (340 psi). The output flow rate changes approximately 6 L/min (1.6 US gpm) for each 100 kPa (14 psi) of power shift pressure
