  8. Cut both the input and output hoses of the fluid transfer pump to approximately 26" (66 cm).
  9. Insert the output hose of the fluid transfer pump into the fill hole of the front drive unit until fully seated, and then pull the output hose back 5mm.
  10. Set up the fill process by putting the container with the measured fluid in the drain basket, and then fully submerge the input hose of the fluid transfer pump and prime the pump. See Fluids for required gearbox fluid.
  11. Connect the 12V power supply to the oil pump using the oil pump switchbox special tool and the XP-10 jump pack.
  12. With an assistant, pump gearbox fluid into the front drive unit assembly as follows:
    Informational PurposesAn informational icon, calling your attention
    Note
    The minimum refill capacity of the front drive unit assembly is 1.8 liters. Using excess gearbox fluid in the fill container allows the oil pump to dispense the full 1.8L without drawing air. Make sure that there is less than 200mL left when completed. Pumping the full 2 liters is not required.
    1. Pump 5 full strokes from the fluid container with the manual pump.
    2. Run the oil pump via the switch box for the entire fill, and then keep running the oil pump until the fill plug is installed.
