5.4 Mounting the stator with the spindle housing
For joining by heating the spindle housing (shrink fit):
● Hot-air oven with temperature monitoring
– Oven volume appropriate for the stator type
– Placement of the oven in the immediate vicinity of the workplace
● Device for cooling the heated-up cooling jacket.

Mounting preparation
Procedure
1. Check that the components are correct and complete.
2. Check the insulation resistance before mounting stators that have been stored for a
longer period. See Chapter "Test the insulation resistance (Page 125)".
3. Clean the surfaces to be joined

All surfaces must be free from contamination, rust, sharp edges, shrink holes, damage
and machining marks, in particular:
– The ring slots for the O-ring seals
– The cooling thread on the cooling jacket (for the stator with cooling jacket variant)
– The spindle housing
– The cable duct in the spindle housing
– The drain holes
