Damage to the gearbox caused by incorrect oil quantities
The oil quantity and the position of the sealing elements are determined by the mounting
position.
After removing the oil level screw, the oil level may not be below the specified fill level.
Damage to the gearbox due to open oil holes
Dirt and damaging atmosphere can penetrate through open oil holes.
Close the gearbox immediately after checking the oil level or changing the oil.
Note
Information about oil
Refer to the rating plate for the type of oil, oil viscosity and quantity of
oil required.
For oil compatibility, see Recommended lubricants (Page 70).
Note
Gearbox sizes 19 and 29
Gearbox sizes 19 and 29 are lubricated for life. There is no opening to
check the oil level. An
oil change is not required.
In mounting positions M2 and M4 the gearboxes are equipped with a breather valve.
C29 has a breather valve in all mounting positions.
- intermediate helical gearbox
In a horizontal operating position the bulging part of the housing of the intermediate
helical gearbox generally faces vertically downwards.
The oil quantity is specified for every individual gearbox and is valid for the standard
mounting position.
Perform the following work for each individual gearbox:
– Check the oil level.
On the main gearbox D/Z, it is not possible to check the oil level in mounting position
M4. The oil level is above the oil level bore so that the bearings above it are lubricated.
– Check the oil quality.
– Change the oil.
– Fill in oil and top it up.
