ABSTRACT:
A hub is mounted or dismounted by the use of hydraulic pressure with the hub being the only movable member. Either of two seals of different diameters are used in conjunction with a third seal of an intermediate diameter so as to establish a differential annular area between the two seals in use. Depending upon which pair of seals is used, hydraulic pressure tends to either force the hub onto or off of the shaft.
