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 the solenoid valve to be measured. Install tee (ST 6451), hose (Parts Number: 4216453), adapter (ST 6461) and pres- sure gauge (ST 6942). Solenoid Valve Pressure Gauge T157-05-04-002 Hose Adapter Tee : 17 mm, 19 mm, 22 mm Connect Dr. ZX and select the monitoring func- tion. 4. Start the engine. Confirm that no oil leakage is observed at the pressure gauge connection. 5.
Maintain the hydraulic oil temperature at 50 ± 5 ° C (122 ± 41 ° F). T4-5-5
