Fig. 23 Model KF, shaft bearing
3. Remove the bearing nut (34) and the guard plate (35) .
4. Remove the outer race of the cylindrical roller bearing.
Note: All parts that are gray in the above figure remain on
the shaft.
5. Clean the surfaces of all parts and check for damage. Replace
if necessary.
6. Relubricate the cylindrical roller bearing (31) . We recom-
mended using: JAX Halo-Guard FG-2 bearing grease or alter-
natively a white NSF H1 grease. Alternatively, use an equiva-
lent brand of lubricant of similar quality and viscosity. See
Table 5 Bearing grease amounts: model KF .
7. Put the outer race back onto the shaft.
8. Place the guard plate and the bearing nut on the shaft, and
tighten the bearing nut.
9. Press the pump shaft with the bearing back into the lantern.
10. Mount the bearing cap (33) .
9.6 Motor Replacement
Special Motor
1. Turn off the motor and prevent it from being able to be
turned on accidentally.
2. Remove the pump head (see Chapter 9.8, " Pump Head Re-
moval," page 18 ).
3. Replace the special motor.
4. Replace the mechanical seal if necessary, and mount the
pump head (see Chapter 9.10, "Pump Head Attachment,"
page 20 ).
IEC Standard Motor for FPE and FP...V
1. Turn off the motor and prevent it from being able to be
turned on accidentally.
2. Remove the pump head (see Chapter 9.8, " Pump Head Re-
moval," page 18 ).
3. Take the lantern off of the motor.
4. Remove the shaft.
5. Replace the motor.
6. Mount the shaft and align (see Chapter 9.11, "Models FPE and
FP…V: Mounting and Alignment of the Pump Shaft," page 27 ).
7. Mount the lantern.
8. Only for flange connection: Check the clearance if necessary
(see Chapter 9.9, "Checking of the Clearances," page 18 ).
9. Replace the mechanical seal, and mount the pump head (see
Chapter 9.10, "Pump Head Attachment," page 20 ).
IEC Standard Motor for Model KF
1. Turn off the motor and prevent it from being able to be
turned on accidentally.
2. Take the motor off of the compact bearing support with
base.
3. Dispose of the motor in an environmentally friendly manner.
See Chapter 2.6.5, "Disposal of Electrical and Electronic Scrap,"
page 7 .
4. Insert the key of the old motor into the new motor.
5. Screw the motor to the compact bearing support with base.
IEC Standard Motor for Model L
1. Turn off the motor and prevent it from being able to be
turned on accidentally.
2. Remove the coupling guard.
3. Detach the motor from the base frame or the foundation.
4. Take the coupling parts off of the motor.
5. Dispose of the motor in an environmentally friendly manner.
See Chapter 2.6.5, "Disposal of Electrical and Electronic Scrap,"
page 7 .
6. Mount the coupling parts onto the replacement motor (pro-
ceed as described in Chapter 9.12, "Model L: Coupling Replace-
ment," page 27 to replace the coupling).
7. Place the replacement motor on the base frame or the foun-
dation.
8. Check the parallel and angular misalignment of the shafts.
Fig. 24 Parallel misalignment
Fig. 25 Angular misalignment
9. Minimize deviations from the angular and parallel misalign-
ment. Realign the shafts if necessary.
10. Screw the motor to the base frame or the foundation.
11. Mount the coupling guard.
