[Also in Group XXIII] A shaft, intended for carrying thereon a plurality of interference fitted members, is provided with a single axially-extending fluid supply passage from which branch passages extend to the surface of the shaft at positions spaced along its length for supplying fluid pressure to the respective interference fitted members mounted thereon for the purpose of facilitating their removal, and with rotary control valve means whereby fluid pressure can be supplied to the branch passages. In an embodiment the shaft 1 has a tapering end portion 2 on which is mounted with an interference fit three roller bearing race rings 3, 4 and 5. The shaft is provided with a bore 8 from which radial passages 11 aligned in a common plane communicate with annular grooves 13 in the shaft surface on which the race rings are mounted. A fluid pressure feed tube 15 is rotatably mounted in the bore 8 and is provided with ports 20, 21 and 22 equiangularly disposed around its periphery for feeding fluid to the radial passages. Seals 25 prevent pressure fluid from leaking through the closed ports. In a modification the feed ports in the feed tube are in alignment and the radial passages are angularly disposed in the shaft (Fig. 8). The shaft may be of stepped cylindrical form in order to reduce the distance by which the interference fitted members need to be moved before being freed from the shaft.
