7. Screw the second grub screw with Teflon sealing tape tightly into the sleeve thread.
8. Force the oil with the hand pump slowly until the pressure of approx. 50 MPa (500 bar) is
reached.
WARNING
Danger to life caused by oil under high pressure
The spurting of oil and/or mechanical damage from the hydraulic system can cause
severe injury or death.
• Use only intact devices and tools for the removal process.
• Observe the prescribed pressures.
9. Allow the oil to act for approximately 15 minutes.
→ The oil penetrates the fitting gaps and distributes itself.
10.Increase the pressure to approx. 65 to 70 MPa (650 to 700 bar) until the oil escapes at
both sides of the press fit.
→ The rotor core automatically slides off the spindle shaft.
Note
A few
oil drops can spurt out in the axial direction.
The rotor core movement is limited by the prism
④.
If necessary, support the loosening of the rotor core by tapping lightly, for example, with a
soft
-faced hammer.
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.
