One cylinder on my machine has no force, what could be the problem, given that every thing else hydraulic is operating normally?
A. Force is a function of pressure (Rule 6). You only experience pressure when there is a restriction to flow (Rule 1). Knowing that the fault is limited to only one cylinder and that a system requires a restriction to flow, a suggestion would be to start with the cylinder and its associated valve. The problem could be with cylinder seals, a pressure valve failing to allow easy passage of fluid or a directional valve not shifting. At EXCEL, our vans are equipped with an array of test equipment to make these tests and checks so much easier and more effective.
