10.2 Change of motor oil
Motor oil quantities
The table states how much oil the SEG pumps must
have in the oil chamber:
Draining the motor oil
1. Slacken and remove both oil screws to allow all
the oil to drain from the chamber.
2. Check the oil for water and impurities. If the shaft
seal has been removed, the oil will give a good
indication of the condition of the shaft seal.
Filling with motor oil
Pump on horizontal position
1. Place the pump in such a position that it is lying
on the stator housing and the discharge flange
and that the oil screws are pointing upwards.
See fig. 11.
2. Fill oil into the oil chamber through the upper hole
until it starts running out of the lower hole. The oil
level is now correct.
3. Fit both oil screws using the packing material
included in the kit. See section
Fig. 11
Oil filling holes
Filling with motor oil
Pump on vertical position
1. Place the pump upright position on a plane,
horizontal surface.
2. Fill oil into the oil chamber through one of the
holes until it starts running out of the other hole.
For oil quality, see the table above.
3. Fit both oil screws using the packing material
included in the kit. See section
.
10.3 Checking the shaft seal
To make sure that the shaft seal is intact, the oil
should be checked.
If the oil is greyish white like milk or contains a large
quantity of water, the shaft seal should be replaced
as the primary part of the seal is worn. If the seal is
still used, the motor will be damaged within a short
time.
If the oil is clean, it can be reused.
10.4 Adjustment of impeller clearance
To adjust impeller you need to dismantle the grinder
system first:
1. See section
.
2. Set the pump on horizontal position on the table.
3. Remove the screw (188a) from the pump
feet (M).
4. Loosen the grinder ring (44) by knocking it
clockwise with punch (F and L). See fig. 12.

Warning
When slackening the screws of the oil
chamber, note that pressure may have
built up in the chamber. Do not remove
the screws until the pressure has been
fully relieved.
