MOUNTING AND DISMOUNTING OF ROLLER BEARINGS

Drive the bearing on the taper just enough so there is some interference; then build up hydraulic pressure under the bore of the bearing. A pressure of 3000 to 6000 psi will be needed, but with this pressure between the bore of the bearing and the shaft it is possible to float the bearing up the taper with much less torque applied to the lock nut or clamp plate than in a dry mounting.
