Procedure for Changing or Re-lling Gearbox Oil Level
• Lay the drive unit at on the ground with the oil ll bung facing up. Using an 8mm (0.31") Allen key
remove the bung. To drain oil, turn the drive until the hole is facing down. Allow to drain until all oil has
been removed (E).
• Rotate the unit until the oil ll hole is sitting between 60º - 70º from horizontal (F).
• Once the ller hole is at approximately 60º the oil should be sitting at the base of the ller hole thread
(G).
• If the oil level is too low to reach the thread it should be topped up. Rotate the unit so the ller hole is
sitting at the top and add oil. Repeat steps 2 - 4 until you have achieved the correct level.
• Note that the oil takes time to work it’s way through the gearbox. Allow time for it to settle once it
has reached the bung hole. Then check the level again until all seepage has occurred.
