A guide means (50) for use in removing and fitting a piston (2) of a crosshead engine includes means (51, 53, 60) for detachably securing the guide means to a piston rod (4) affixed to the piston. A support device (54) lies in the proximity of the wall surface (11) of a cylinder (1) containing the piston, and functions to enable the guide means to hold the piston rod (4) in a central region of the cylinder as the piston is lifted up from the cylinder. |
