Prior to loosening the grub
screws, mark respectively meas-
ure the position of the mechanical seal on the
shaft protection sleeve or the drive shaft. Do not
slide the O-ring across the pressure spot of the
screw!
!
With designs with shaft protection sleeve, pull the
shaft protection sleeve (206) and the O-ring (115)
off the drive shaft (118).
•
Dismounting the mechanical seal, single-
acting with quench
!
Pull the mechanical seal housing (214) with the
counter-ring of the mechanical seal (atmosphere
side) (219) off the drive shaft (118).
Note:
Make sure that you pull off the casing with
the mechanical seal counter-ring concentric and
that it doesn't get jammed in order to prevent
damage to the counter-ring.
!
Press the mechanical seal counter-ring and the
O-ring out of the mechanical seal housing (214).
Exert pressure evenly.
!
Drive out the locking pin (220).
!
Loosen the grub screws in the rotating part of the
mechanical seal if provided (219) and pull the me-
chanical seal off the drive shaft (118).
Prior to loosening the grub
screws, mark respectively
measure the position of the mechanical seal on
the shaft protection sleeve or the drive shaft. Do
not slide the O-ring across the pressure spot of
the screw!

acting with throttle ring
!
Remove the hexagon screws (245).
!

7.2.1.5 Dismounting the angular contact and the groove
ball bearings
Dismounting the bearings takes place after dismount-
ing the drive shaft. See Chapter 7.2.1.4.
!
Move the spacer sleeve (102) radial and drive off
the groove ball bearing (103) with a suitable tool
(driver) out of the bearing bracket (110) (see fig-
ure 6).
