Operating Instructions, 02/2021, A5E37880173A/RS-AM
Note
Tandem gearbox - 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.
Note
Gearbox in special mounting position
The gearbox is intended for a specific rotation angle and is delivered with the correct quantity
of oil for this purpose.
It is not possible to check the oil level. You will find information regarding oil quantity and
type of oil on the rating plate.
When draining the oil a higher residual quantity of oil may remain in the gearbox. When you
carry out an oil change remove any residual oil.
8.3.2 Checking the oil level
NOTICE
The gearbox oil volume changes depending on the temperature
If the temperature rises, the volume increases. Where temperature differences and filling
quantities are significant, the volume difference can amount to several liters.
The oil level must therefore be checked while still slightly warm, approximately 30 minutes
after switching off the drive unit.
