Make sure that the anti-torsion insert 566/2 is ap-
prox. 2 mm shorter than the plain bearing.
♦ Insert distance ring 504/1 and then bearing bush
545/2
.
♦ Carefully press the thrust ring 510/2 into the impel-
ler 230 right to the stop. In doing so, pay attention
to the correct position of the anti-rotation grooves
relative to the driving props in the impeller 230 .
♦ Check whether the thrust ring protrudes about 2
mm out of the impeller. See Fig. 7

♦ Check fit of drive magnet assembly
858
/ drive
shaft
213
.
Put 1 drop of adhesive on the thread of the drive
shaft, e.g. Loctite 243 or an equivalent.
Only 1 drop of the adhesive should be applied.
Otherwise the next dismantling operation will be
more difficult or no longer possible without de-
stroying components.
♦ Mount drive magnet assembly
