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 no be confused with incorrect leaks from the ear.
Leaks at the o-rings, however, are not acceptable and must be attended to immediately in
order to avoid any damage to the bearing!
Check the o-rings in the front ear of the balancing device for leaks, as shown and detailed
below.
