exchanged as an assembly.
2.2.3.1 REMOVING THE PLANETARY HUB REDUCTION GEARBOX FROM THE TRACTION
MOTOR
- Jack up and secure the truck.
- Remove the wheel nuts and wheels.
- Place an oil pan underneath the gearbox.
- Remove the oil filler plug (1).
- Remove the oil drain plug (14) and copper sealing ring (15).

- Remove the 14 socket head screws (13).
- Remove the planetary hub reduction gearbox from the bearing plate, taking care not to lose the O-ring (17).
- Clean the sealing areas.
2.2.3.2 DISASSEMBLY OF THE PLANETARY HUB REDUCTION GEARBOX
- Remove the hexagonal head screw (6).
NOTE: The hexagon head screw (6) is self-locking and can therefore only be used once.
- Remove the two plugs (8).
- Use a puller to extract the flange (10).
- Put the flange (10) aside and secure it against sliding.
- Insert a drift alternately into the two access holes (9) and knock the bearing inner race (12) off the flange.
- Remove and renew the shaft sealing ring (11).
- The O-ring (4) is accessible after pressing out the washer (7) from the flange (10).
- Check and renew, if necessary, O-rings (5) and (4).
NOTE: There are shims (3) mounted between the flange (10) and washer (7). During assembly all shims
must be installed again with the 0.5 mm shim on the profile side of the flange (10).
2.2.3.3 ASSEMBLY OF THE PLANETARY HUB REDUCTION GEARBOX
- Put the gearbox housing vertical and secure it against sliding.
- Install the bearing inner race (12), making sure that it is seated evenly.
- Half fill the sealing shaft ring (11) with grease and drive it into the housing (2).
- Install the shims (3) in the flange (10).
