Dismanting of a hub-shaft connection with oil film. This method is used for connections stacked on a cone. In this application two pumps of maximum pressure of 40,600 psi and a 60-tonne cylinder were used. Stacking the gear wheel hub on the tapered main shaft is often used in high-power transmission. Assembly and dismanting of this kind of connections can be executed without heating of the parts. The use of high-tonnage presses is also not necessary. These activities can be executed directly on the machine.
