If a leak is visible or if the motor is more than one year old (e.g. in the event of re-use or after long storage):
Check the fluid level in the motor prior to installing it.
You need the following tools for assembly and inspection work:
•
Insulation measuring unit: 500 VDC testing
•
Filling Kit 308 726 103
Determine the age of the motor by checking the type plate (see Figure 5-1).

Figure 5-2: Venting the motor
Figure 5-3: Checking the motor fluid
Place the motor horizontally so that the filling valve is
located at the highest position.
Remove the plug (3) from the filling valve.
Carefully push the test pin (2) into the filling valve until air
and some fluid escape from it.
Feed the test pin (2) through the opening (1) in the
diaphragm housing until you can feel resistance.
Measure the actual diaphragm distance to the side of the
opening in the diaphragm cover.
If the measured result is not identical to the target value:
59 mm 2 mm (6"- motor-WW 4-30kW)
25 mm 2 mm (6"- motor-304SS/316SS / 4-30kW)
47 mm 2 mm (6"- motor-304SS/316SS - 37/45kW)
47 mm 2 mm (6"- HighTemp90, 304SS/316SS)
44 mm 2 mm (6"- 45kN Version)
37 mm 2 mm (8"- motors all)
