♦ Remove bearing pedestal
330
for the centering of
the bracket
344
. If necessary, use two levers.
♦ To overcome the axial magnetic forces, pull the
bearing pedestal 330 with a firm jerk in the direc-
tion of the motor.
CAUTION! When pulling out the bearing
pedestal, the axial magnetic forces (up to
max. 400 N without weight force) decrease
abruptly after being at
maximum. (Risk of accident)
For procedure, see Section 7.6.2 .
7.7 Notes on assembly
♦ Use original spare parts. See also
Section 2.4
.
♦ Do not use any defective parts.
♦ Apply Anti-Seize special assembly paste (e.g. from
Weicon) to the fitting surfaces (not any stainless
steel surfaces) and screw thread prior to assem-
bly.
♦ Check whether all parts fit and only then assem-
ble.
♦ Important dimensions (centerings, bearing fits or
bearing play) are to be checked prior to assembly.
If necessary, perform a trial assembly.
♦ We recommend that the housing gasket
401
, the
cover gasket
403
(oil bath lubrication) and the
shaft sleeve
523/1
be replaced during every new
assembly.
♦ Always replace the circlip
932/7
.
♦ Remove metallic particles adhering to magnetic
components such as the inner magnet assembly
859
and the drive magnet assembly
858
prior to
assembly.
For this purpose simple plasticene can be used.
7.7.1 Table for target dimension Z
The plain bearings require a minimum axial play for
perfect functioning. This axial play "Z" must be
checked using the drawing Fig. 6 after completion of
assembly.

7.8 Assembly
A complete assembly process is described in the
following.
Sub-sections can be deduced from this.
7.8.1 Assembly of housing / shaft spi-
der
♦ Push or press the shaft spider 338 into the hous-
ing 100 together with the two anti-torsion inserts
566/1 .
Use a suitable plastic tube for pressing.
The pressing force must only be applied
over the sliding surface of the shaft
spider.
(risk of the silicon carbide breaking)
♦ Insert shaft sleeve
523/1
into the shaft spider
338
.
