Check for leakage
The front ear of the balancing device is lubricated with grease. After filling, excessive
grease may normally be forced out between the shaft and the sealing ring in the
sealing spacer. This is normal behaviour and must not be confused with incorrect
leaks from the ear.
Leaks at the o-rings and/or sealings, are not acceptable and must be attended to
immediately in order to avoid any damage to the bearing!
