1.
Check that the four O-ring seals are fitted correctly.
2.
Take the stator at the support arm.
3.
Position the spindle housing so that you can route the electrical cables through the cable
gland of the spindle housing or the bearing shield.
4.
Insert the stator horizontally in the spindle housing. When inserting, ensure that the O-
ring seals remain in the stator slots.
5.
Thread the connection cables through the cable gland.
6.
Attach the bearing shield.
7.
Bolt the bearing shield or mounting shield onto the cooling jacket. See Chapter "Mounting
the motor spindle (Page 86)".
–
First tighten all bolts with half the maximum tightening torque.
–
Then tighten the bolts with a torque wrench diagonally to the maximum tightening
torque. See "Tightening torques" table.
Use a liquid medium to check whether the spindle housing is sealed properly. Test
pressure 0.7 MPa (7 bar).
–
Turn the spindle housing so that the drain holes are facing downwards.
8.
If the spindle housing leaks, dismantle the spindle housing.
–
Replace the O-ring seals.
–
Debur any sharp edges.
9.
Remount the spindle housing.
You have mounted the spindle housing.
