OPERATIONAL PERFORMANCE TEST / Component Test SOLENOID VALVE SET PRESSURE Measure solenoid valve set pressure by using both Dr. ZX and the pressure gauge. Preparation: 1. Stop the engine. 2. Push the air bleed valve on top of the hydraulic oil tank and release any remaining pressure. 3. Remove the line from port X in the charging block. Install a tee, a hose and adapter (ST 6461). In- stall pressure gauge (ST 6942). : 17 mm, 19 mm, 22 mm Install Dr. ZX and select the monitoring function. 4. Start the engine. Check for any oil leaks at the pressure gauge connection. 5. Maintain the hydraulic oil temperature at 50 ± 5 ° C (122 ± 41 ° F). Measurement: 1. Set engine speed at fast idle. 2.
Measure without depressing the accelerator pedal. Measure with the accelerator pedal fully de- pressed. 3. Read the values on both Dr. ZX and the pressure gauge. 4. Repeat the measurement three times and calcu- late the average values. Evaluation: Refer to the performance Standard Table in Group T4-2.
