The HCH hydraulic techniques are often the preferred method for dismounting larger bearings as well as other components. These techniques, which employ hydraulic pumps, nuts and oil injectors, allow the application of substantial forces to dismount bearings or other components.

Warning: large bearings, installed with tight fits, and having been in service for a long period of time, will likely have developed fretting corrosion on fitted surfaces and will require considerable dismounting force.
