DO NOT overfi ll gearbox when replacing
the gear oil. Excessive amount of gear
oil will reduce the amount of room in
the gearbox for expansion and cause
damage to the seals.
IMPORTANT!
The Planetary gearbox used on your Drive Unit uses a gear oil to keep the internal gears lubricated. To check and or replace
the oil, follow the steps below.
CHECKING THE GEAR OIL:
1. Make sure the Drive Unit is in an upright position when checking the oil.
2. Locate the oil level sight port and visually inspect that oil can be seen. If oil can been seen this is an indication that the
oil level is adequate.
CHANGING THE GEAR OIL:
1. Position the Drive unit in a position in which the oil can fl ow freely from the gearbox once the drain plug is removed.
2. Place a drain pan under the drain port.
3. Remove the drain plug
and allow the oil to completely drain out. Allow 10-15 minutes for oil to drain completely.
4. Position the gearbox for fi lling by orientating the unit so that the oil fi ll port is accessible. In most cases the bail housing
will need to be removed to access the oil fi ll port, which is located in the top section of the gearbox, near the motor.
5. Replace oil drain port and fi ll the gearbox with the required amount of gear oil. For the correct capacity of gear oil
refer to the model specifi cation page. The gear oil specifi cations is listed below:
