(54) Title: EXCHANGE OF BUSHING IN DRUM (57) : The invention concerns a drum (3) assembly for a mooring winch and a method of exchanging a bushing (6) within the drum (3) assembly. The drum (3) assembly comprises a rotatable drum shaft (1) having a rotational axis along the drum shaft (1), a drum support (2) comprising a first pedestal (2B) supporting a first axial end (3A) of the drum shaft (1) and a second pedestal (2B) supporting a second axial end (3B) of the drum shaft (1) and an axially slidable drum (3) arranged between the first and second pedestals (2A, 2B). Both a first axial end (3A) of the drum (3) and a second axial end (3B) of the drum (3) is supported on a bushing (6) axially surrounding the drum shaft (1). A drum (3) length difference (L, L') corresponding to the minimum distance between the two pedestals (2A, 2B) minus the axial length of the drum (3) is equal or longer that the axial length of each bushing.
