Oil / Motor check
3.1
Oil check
If the pump is connected to an external starter and
the leakage monitor lamp lights up then the oil must
be checked. Check the leakage-seal monitor by dis-
connecting the leakage-lead from the terminal board.
Measure the insulation between the leakage-lead and
Earth. The value should be larger than 100 kΩ, if it is
not the oil should be checked.
J 205 - J 405:
Unscrew outer and inner oil plug
(Figure 7)
J 604:
Unscrew oil plug
Hint!
To ease the drain of the oil on J 405 and J 604
unscrew both of the oil plugs on the pump.
Hint!
Put some grease on the hex tool to lift up the
inner oil screw on J 405.
Hint!
If pump will be completely dismantled the drain
of the oil can be done later in the overhaul. See sec-
tion 7
m
CAUTION! The lifting tackle must always
be designed to suit the pump weight.
TILT THE PUMP OR LAY THE PUMP DOWN IN
HORIZONTAL POSITION. REMEMBER TO ALWAYS
SECURE THE PUMP WITH THE LIFTING CHAIN.
Drain off the oil into a clean can and examine it. If it
is clean and contains no water, the mechanical seal
unit / shaft seals are free from defects and can be
used again. If the oil contains water (milky emulsion)
and sediments, the mechanical seal unit / shaft seals
must be changed and the lower ball bearing checked.
3.2
Motor check J 205
Unscrew inspection plug marked ”Motor” and check
that no water or oil has entered into the motor hous-
ing.
Hint!
Use an air tool to blow into motor housing and
check if water comes out of housing. For motor check
on J 405, J 604 see section 7.
