10.Increase the pressure to approx. 60 to 70 MPa (600 to 700 bar) until the oil escapes at
both sides of the press fit. If the oil escapes only at one side, retain pressure by
repumping.
→ The rotor core slides off the spindle of its own accord.
Note
A few oil drops can spurt out in the axial direction.
The rotor movement is limited by the prism.
If necessary, support the loosening of the rotor core by tapping lightly, for example, with a
soft-faced hammer.
Consult your Siemens representative if dismantling is not successful.
11.Check the joint surfaces for scratches or marks in the longitudinal direction.
Note
Scratches or marks in the longitudinal direction inhibit the pressure build-up in
subsequent dismantling operations and consequently the release of the joined
components.
You have dismantled the rotor core.
