Dismantling and assembly of the rotating unit
The first step is to remove the snap ring (096) from the retainer
(780). The springs are compressed to achieve this. This can
be done by using a simple tool, as illustrated.
Lapped surfaces of the rotating face must
be protected.
Wing nut
Baseplate
Locking nut
protective support
Thrust plate with

Grub screw
1. The rotating face (574 / 578) is pushed down and the snap
ring (096) is removed from the groove using a pointed tool.
2. Now remove in the following sequence: the rotating face
(574 / 578), the O--ring (123), the thrust ring (583) and the
springs (582 / 092).
Assembly is carried out in reverse sequence.
The following must be noted during assembly:
The drive cams in the retainer (780) must engage into the groo-
ves of the thrust ring (583) or the rotating face (574 / 578) .
Fit the snap ring (096) into the groove of the retainer (780), lea-
ving one end of the snap ring protruding by approx 6 -- 12 mm
to the side of the drilled hole.
At the outer circumference of the retainer (780) there are 2 mar-
ker grooves. The lower one runs precisely through the centre
of the drilled hole for the internal socket head screws, which in-
dicates that the thread of the screws is metric.
The upper groove assists during installation. If the initial ten-
sion of the mechanical seal is set correctly to the installation
length, then the thrust ring shall be in alignment (be flush) with
this groove.
