21.
Fit the new O-ring (1) onto the rotating seal holding bush (2).
Only reuse an old O-ring when damage can be completely
ruled out.
NOTE!
Installing the O-ring
Depending on the installation conditions, it might be easier
to push the O-ring (1) into the groove of the rotating seal
holding bush (2) prior to screwing in the rotating seal holding
bush using the Multitool (12). In doing so, ensure that the O-
ring (1) is not damaged and not pushed out of its seat.
22.
Install the second rotating seal holding bush with new
mechanical seal in the same way.
23.
Oil the outer surfaces of the shafts [W] and the fit bores of the
rotors and install the rotors in accordance with
6.3.3 “Rotors, removal and replacement” on page 128
depending on the rotor type.
24.
Check that the rotors run smoothly:
— If a rotating seal holding bush is screwed in too far, the
rotors rub against the gear-side casing protection plate
and the shaft can only turn with difficulty.
Remove the rotors and unscrew the relevant rotating seal
holding bush by
1
/
12
th of a turn (one groove).
— If a rotating seal holding bush was not screwed in far
enough, the rotor will protrude on the cover side. In this
case, the rotor will rub on the cover-side casing protection
plate when the ring nuts are tightened.
If necessary, screw in the rotating seal holding bush fur-
ther by
1
/
12
th of a turn (one groove).
25.
Attach the cover-side casing protection plate and quick-
release cover, see
Chapter 6.3.2 “Opening and closing the
quick-release cover” on page 125
