Internal radial o-rings

If oil stains are found at the points of attachment of the drive shafts in the gearbox, it is necessary to replace the sealing rings without completely disassembling the shaft. To do this, do the following:

- Disconnect the corresponding shaft from the inside from the gearbox;

- lubricate the new O-ring with a small amount of grease along the sealing lip;

- press the ring with a mandrel into the gearbox so that the outer side is flush;

- Install the drive shaft.
