This disclosure includes methods for testing hydraulically-actuated devices and related systems. Some hydraulically-actuated devices have a housing defining an interior volume and a piston disposed within the interior volume and dividing the interior volume into a first chamber and a second chamber, where the piston is movable relative to the housing between a maximum first position and a maximum second position in response to pressure differentials between the first and second chambers. Some methods include: (1) moving the piston to the first position by varying pressure within at least one of the first and second chambers such that pressure within the second chamber is higher than pressure within the first chamber; and (2) while the piston remains in the first position: (a) reducing pressure within the second chamber and/or increasing pressure within the first chamber; and (b) increasing pressure within the second chamber and/or decreasing pressure within the first chamber.
A method for testing a hydraulically-actuated device having a housing defining an interior volume and a piston disposed within the interior volume such that the piston divides the interior volume into a first chamber and a second chamber, where the piston is movable relative to the housing to a maximum first position in response to pressure within the second chamber being higher than pressure within the first chamber and to a maximum second position in response to pressure within the first chamber being higher than pressure within the second chamber, the method comprising:
