Abstract
In various aspects, a method of detecting surface irregularities on or in an internal surface of a cylinder for use in a piston-cylinder assembly is disclosed. The method can include (A) fixing a position of and an orientation of a first one of the cylinder and a piston; (B) configuring a positioner and a dynamometer to move a dynamometer and a second one of the cylinder and the piston along a common longitudinal axis, the dynamometer being mechanically coupled to the second one; (C) moving the second one relative to the first one along the common longitudinal axis between a first position and a second position, the piston being located inside the cylinder at the first position and at the second position; and (D) measuring, by the dynamometer, a frictional force between the piston and the cylinder during the movement.
