WebJan 27, 2024 · The test procedure is as follows: Test procedure Secure the hydraulic cylinder with the service ports up. Both sides of the cylinder should be filled with hydraulic fluid through the service ports. Follow the … WebIn this condition, due to the unequal volume on either side of the piston, fluid pressure equalizes and the cylinder becomes hydraulically locked. Once this occurs, the cylinder can move only if fluid escapes from the cylinder via the rod seal or its ports. Figure 1. Double-rod cylinder - oil volume is equal on both sides of the piston
