Abstract
The present invention relates to a tool for screwing a piston onto the piston rod of a hydraulic cylinder, in particular of a hydraulic cylinder with a piston diameter of more than 200 mm, comprising a first tool element with connecting elements for releasable connection with the piston and a second tool element with connecting elements for releasable connection with the piston rod, which is rotatable with respect to the first tool element, wherein the torque necessary for screwing together piston and piston rod can be applied onto the piston and the piston rod via the connecting elements by rotating the first tool element against the second tool element.
