    Informational PurposesAn informational icon, calling your attention
    Note
    Trim both the input and output hoses to 26", insert the output hose into the fill hole until fully seated, and then pull back 5mm.
  7. Place the measured fluid container in the drain basket, fully submerge the input hose, then prime the pump with KAF 1 fluid.
  8. With assistance, pump KAF 1 fluid into the rear drive unit.
    Informational PurposesAn informational icon, calling your attention
    Note
    The minimum refill capacity of the rear drive unit assembly is 2.1 liters. Using excess gearbox fluid in the fill container allows the oil pump to dispense the full 2.1L without drawing air. Make sure that there is less than 200mL left when completed. Pumping the full 2.3 liters is not required.
    Informational PurposesAn informational icon, calling your attention
    Note
    The assistant will run the oil pump switch box using XP-10 Jump Pack and have the rear drive unit fill plug ready for installation.
    Informational PurposesAn informational icon, calling your attention
    Note
    Do not run the pump dry. Pump 5 full strokes from fluid container while simultaneously running the oil pump switch box for entire fill process. Keep running the oil pump switch box until the drain plug is installed in the next step. If the pump is not running or the drain plug is not installed, fluid will drain from plug within 10 seconds.
  9. Install the fill plug into the rear drive unit.
