A new O-ring has been inserted into the groove of motor housing cover 812.
1. Attach the lifting equipment to bail 571, lift up motor housing cover 812 and
lower it down onto motor housing 811 or motor unit 80-1 until only a gap
remains which allows work to continue. Watch the alignment grooves in motor
housing cover 812 and motor housing 811. The grooves must be aligned
correctly.
2. Connect plug 81-2 of the control cable to the corresponding connector.
3. Connect the power cable cores to terminal board 835 with disc 550.23, circlip
932.23 and nuts 920.23/920.24 in accordance with the wiring diagram.
4. Tie the cores of the control and power cables together with cable ties.
5. Slowly lower motor housing cover 812 onto motor housing 811. Watch the
alignment grooves in motor housing cover 812 and motor housing 811. The
grooves must be aligned correctly.
6. Fasten motor housing cover 812 to motor housing 811 or motor unit 80-1 with
hexagon socket head cap screws 914.01 and secure them with Loctite 243.

7.7.4 Installing the mechanical seal
Observe the following to ensure trouble-free operation of the mechanical seal:
▪
Only remove the protective wrapping of the contact faces immediately before
assembly takes place.
▪ The shaft surface must be absolutely clean and undamaged.
▪
Immediately before installing the mechanical seal, wet the contact faces with a
drop of oil.
▪
For easier installation of bellows-type mechanical seals, wet the inside diameter
of the bellows or the O-rings with soapy water (not oil).
▪
Cover any grooves in the shaft into which the O-rings could slide with suitable
means or assembly aids.
▪
To prevent any damage to the rubber bellows, place a thin foil (of approximately
0.1 to 0.3 mm thickness) around the free shaft stub.
Slide the rotating assembly over the foil into its installation position.
Then remove the foil.
