Inspecting the transparent oil plugs
The gearboxes are equipped with transparent plugs, through which oil leakage
from the hubs can be detected. If an oil leakage is detected, remove the hub and
replace the defective part (radial sealing or o-ring).
Note
If only a few drops of oil are detected, is not necessarily a sign of an oil leakage.
A few drops of oil inside can normally be released from the hub. But if oil
increases, this is not the case.
