Filling In Oil - Siemens SIMOGEAR BA 2030 Operating Instructions Manual

Service and maintenance
8.2 Checking and changing lubricants
Note
Polyglycol oil has a higher density than mineral oil. Therefore, it sinks down towards the oil
drain and the mineral oil floats on top.
This makes the required complete draining of mineral oil from the gearbox extremely
difficult.
Note
After the second flush, we recommend that an appropriate analysis institute checks the
quality of the flushed fluid.
Observe the symbols in the diagrams of the Mounting positions (Page 84):
Venting
Procedure
1. After the oil has been drained, wipe the gearbox clean of any remaining mineral oil using a
cloth.
2. Unscrew the vent plug.
3. Fill the gearbox with a flushing oil, using a filter (filter mesh max. 25 μm). For the flushing
oil, use either the new oil or one that is compatible with the new oil and is less expensive.
4. Operate the gearbox for 15 to 30 minutes under a low load.
5. Place a suitable and sufficiently large receptacle underneath the oil drain plug.
6. Remove the oil drain plug. Drain all the oil into the receptacle.
7. After flushing, immediately seal the gearbox using the sealing element.
8. Repeat this step for the second flushing.
You have now flushed the gearbox twice and can pour in the new oil.

NOTICE
Mixing of different oils impairs the lubricity
When adding oil, use the same oil type and viscosity. If changing mutually incompatible oils,
see Flushing the gearbox (Page 65).
