!
Push out the joint bolt (301).
!
With a brass driver, drive out the two sleeves for
the joint bolts halfway (303). Slant the joint shaft
(307) for that purpose (see figure 4).

!
Pull the rotor (401) off the joint shaft (307).
!
Press out the joint bush (302) from the joint shaft
(307) (n/a with AE1L 51 / AE1L 101

!
Drive out the sleeve for the joint bolt (303) all the
way out of the rotor (401) with the brass spike.
7.2.1.3 Dismounting the joint shaft and the drive side
joint
Disassembly of the joint shaft and the joint of the drive
side takes place after dismounting the stator (402)
and the rotor (401). See Chapter 7.2.1.1 and 7.2.1.2.
!
Dismantle the joint on the drive side as described
in Chapter 7.2.1.2.
!
Pull the joint shaft (307) off the drive shaft (118).
!
Press the joint bush (302) out of the joint shaft
(307).
!
Completely drive the sleeve for the joint bolt (303)
out of the drive shaft (118) with the brass spike.
7.2.1.4 Dismounting the shaft seal and the drive shaft
Note:
In case of pumps with shaft sealing by means
of stuffing box, you can change the packing rings as
described in Chapter 7.1.2.3 without dismounting the
drive shaft. Dismounting the drive shaft is required
when the pump is equipped with a mechanical seal.
In case of damages to the drive shaft or shaft protec-
tion sleeve in the area of the shaft seal, the pump
must also be dismounted as described in the follow-
ing.
!
Dismantle the stator (402) (see Chapter 7.2.1.1).
!
Remove the hexagon nuts (607) and serrated lock
washers (608) as well as the hexagon screws
(606).
!
Pull the suction casing (505) across the rotor
(401). Make sure that the finely crafted rotor is not
damaged.
!
Take off the g
asket for suction casing
(501).
!
Pull of the clutch half respectively pulley and re-
move the feather key (101).
!
Unscrew the hexagon nuts (139) and remove the
bearing cover (131) with the seal (132).
!
Unscrew the bearing nut (116) from the drive shaft
(118).
!
Press the drive shaft (118) with the attached rotor
(401), the attached joint shaft (307) and the
mounted shaft seal out of the bearing bracket
(110).
!
To do so, apply the press-on device to the bearing
bracket (110) (see figure 5).
Note:
Guide sleeve and press-off cover serve as
assembly aids and can be purchased from us.

!
Pull off the thrower (114) from the drive shaft
(118).
•
Dismounting the stuffing box
!
Remove the self-locking hexagon nut (202) and
take off the gland halves (203).
!
Pull the stuffing box casing (204) off the drive
shaft (118).
!
Take off the stuffing box packing (207) with de-
signs P02 and P12 including the flushing ring
(208) and with designs P03, P13 and P04, P14
including the sealing chamber ring (209) from the
stuffing box casing (204).
!
For the design with shaft protection sleeve, pull off
the shaft protection sleeve (206) and the O seal
ring (115) from the drive shaft (118).
•
Dismounting the single-acting mechanical
seal
!
Pull off the mechanical seal housing (214) with the
counter-ring of the mechanical seal (219) (atmos-
phere side) off the drive shaft.
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).
