7.2.2 Mounting
the
eccentric screw pump
General
Assembly of the individual pump components after
careful cleaning takes place in reverse direction.
7.2.2.1 Installing the angular contact and groove ball
bearings
Note:
The pumps are equipped with re-greasable ball
bearings. For re-assembly, the ball bearings must be
greased sufficiently.
The groove ball bearing with vertical pump design is
greased for life.
!
If required, clean ball bearings carefully with diesel
fuel. If the bearing surfaces are shiny and undam-
aged, you can reuse the ball bearings (103) and
(104). If this is not the case, replace the ball bear-
ings.
!
Fill the ball bearings (103) and (104) with roller
bearing grease. Apply the grease filling as de-
scribed in the following.
1. Fill the cavities between the roller bearings
approx. 30 to 50% with grease.
2. Strip off excess grease (best with your fingers,
do not use any metal objects). For recom-
mended roller bearing greases, see Chapter
7.1.2.2.
!
Press the double-row angular contact ball bearing
(104) from the drive side with a matching piece of
pipe over the outer ball bearing position ring into
the bearing bracket (110). Oil bearing position
slightly beforehand.
Note:
The ball filling notch of the angular contact
ball bearing must point towards the drive side.
The following pump sizes are
equipped with two single-row
angular contact ball bearings (104):
AE1L
2701 / 5001
AE1E
1450 / 2700 / 5000 / 9500
AED1E
2300 / 4250 / 7800 / 15500
AE2E

AE1N
750 / 1450 / 2700 / 5000
AE2N / AE4N 750 / 1450
AED2N
1200 / 2300 / 4250 / 7800
AE.H
380 / 750 / 1450 / 2700
AE.V
200 / 380 / 750 / 1450
Both bearings have to be pressed into the bearing
bracket (110) in
O-type arrangement
and ad-
justed without play via the shim rings (129) (see
figure 7).
Figure 7: Two single-row angular contact ball bear-
ings with shim rings
!
Insert the circlip (127) in front of the ball bearing
(104) respectively the shim rings (129) into the
bearing bracket (110).
!
Insert the spacer sleeve (102) into the bearing
bracket (110).
!
Fill the space between the bearing bracket (110)
and the spacer sleeve (102) approx. 90% with
roller bearing grease.
For recommended roller bearing greases, see
Chapter 7.1.2.2.
For filling quantities, see table in Chapter 7.1.2.6.
