Abstract
The tool is designed to carried out maintenance operations on a bearing assembly comprising a bushing split into at least two shells; the maintenance tool comprises a device arranged to act on and rotate the bushing shells. In particular, the device comprises a slide and a pin; the slide has a hole transversal to its sliding direction and the pin is slidably mounted inside the hole and protrudes from the hole; in a first operating position the pin acts on a shell and in a second operating position the pin does not act on any shell. The method provides to rotate the bushing shells without rotating the supported shaft, and to carry out maintenance operations on a shell at a time while leaving the shaft supported by the other shell.
