Refill

  1. Fill a 3000mL measuring container with 2.5L/2500mL of KAF1 gearbox fluid.
    Note
    The rear drive unit requires 2.3L/2300mL of fluid, however the excess fluid will prevent underfill and air entrapment.
  2. If not already the correct length, trim the fluid transfer pump hoses to 26 in (660mm) each.
  3. Install the hoses onto the fluid transfer pump.
  4. Place the measuring container and the fluid transfer pump into the oil drain basket.
  5. Insert the output hose of the fluid transfer pump into the fill hole of the rear drive unit until fully seated, then pull back 5 mm.
  6. Fully submerge the input hose of the fluid transfer pump into the measuring container.
  7. Pump 2.3L/2300mL of KAF1 gearbox fluid into the rear drive unit.
    Note
    Make sure the input hose end remains submerged, so that air is not pumped into the gearbox.
    Note
    When properly filled, there should be 200mL or less of gearbox fluid left in the measuring containter.
  8. Remove the output hose from the rear drive unit.
  9. Install the fill plug to the oil pump.
    15 Nm (11.1 lbs-ft)
    Note
    Inspect the O-ring for damage, and if the O-ring is damaged, replace the O-ring.
