7.8 Assembly
A complete assembly operation is described in the
following.
Sub-sections can be deduced from this.
7.8.1 Bearing pedestal
¾
Screw the cleaned oil drain plug 655/1 into the
bearing pedestal 330.
¾
Press both radial ball bearings 321 onto the drive
shaft 213.
¾
Insert key 940/1 into the drive shaft.
¾
Insert rotary shaft seal 421/2 into the bearing ped-
estal 330 .
¾
Install the pre-assembled drive shaft into the bear-
ing pedestal from the motor side.
¾
Insert wavy spring washer 953/1 into the bearing
pedestal.
¾
Mount rear bearing cover 361 with the rotary shaft
seal 421/1 inserted and cover gasket 403 with hex.
socket screws 914/2 .
¾
Mount support bracket 183 with hex. screws 901/2
and contact discs 557/2 .
The attachment slots of the support surface face
towards the housing.
7.8.2 Drive magnet assembly
¾
Clamp the pre-assembled bearing pedestal on the
shaft end in the vice so that the carrier groove ,is
facing upwards.
¾
Mount drive magnet assembly 858 onto the drive
shaft so that the driver cams engage.
¾
Screw in hex. socket screw 914/1 with tooth lock
washer 557/1 . Secure thread, with a drop e.g of
Loctite 234. A hex. socket screw key with a mini-
mum length of 120 mm is required for tightening.
7.8.3 Plain bearing pedestal with impel-
ler, inner magnet assembly and
plain bearings
¾
Insert the plain bearing cartridge 310 into the cen-
tering of the plain bearing pedestal 339 .
¾
Move the plain bearing cartridge into a position
which permits all 3 hex. screws 901/1 to be in-
serted.
¾
Tighten screws with an open-jaw wrench.
For tightening torques, see Section 1.2 .
¾
For single-part inner magnet assembly:
If the parallel pin 562/1 in the clearance bore in the
inner magnet assembly 859 has to be replaced,
force it in carefully. It is to protrude by about 3 mm
towards the impeller. See
Fig. 5 .

¾
For split inner magnet assembly (if necessary):
Press the inner magnet assembly shaft 220 with
key 940/4 fully into the inner magnet assembly
859 . See sectional drawings in Section 9 .
¾
Cut out a small corner on the inside diameter of
the intermediate ring 509/1 so that a recess is pro-
duced for the parallel pin 562/1 (single-part inner
magnet assembly) or the key 940/4 (split inner
magnet assembly).
¾
Then mount the intermediate ring 509/1 onto the
shaft of the inner magnet assembly 859 .
¾
Apply Anti-Seize paste to the shaft and impeller
holder.
¾
Place inner magnet assembly on the workbench
and mount the pre-assembled unit plain bearing
pedestal / plain bearing cartridge from above onto
the inner magnet assembly.
Make sure that the
parallel pin 562/1 (single-part inner magnet as-
sembly) or the key 940/4 (split inner magnet as-
sembly) engages in the carrier groove of the
plain bearing cartridge . To facilitate alignment,
the plain bearing pedestal can be turned to and fro
slightly.
¾
Mount 2
nd
intermediate ring 509/2 onto the drive
shaft.
¾
Mount distance washer 551/1 .
¾
Insert key 940/2 .
¾
Mount impeller 230 .
¾
Insert PTFE O-ring 912/1 into the groove of the
impeller nut 231 .
¾
Tighten impeller nut. Secure it with a drop of e. g.
Loctite 234. Countercheck the inner magnet
assembly with a strap wrench.
For tightening torques, see Section 0 .
¾
It must be possible to easily turn the plain bearing
pedestal 339 by hand. When raising the plain bear-
ing pedestal, a slight axial play of the plain bearing
of up to 1 mm must be felt.
¾
The axial play of the plain bearing is automatically
set during assembly.
