Additional Notes

  • Both the Ford Model GPW and the Willys-Overland Model MB share an identical transfer case fluid capacity of 1.42 liters, which reflects a service fill figure for routine fluid maintenance rather than a full overhaul quantity.
  • The Jeep MB / GPW transfer case fluid change interval is set at 10,000 km under normal use conditions, applying equally to both the GPW and MB variants without distinction between the two.
  • The alignment of capacity and interval figures across the Ford-built GPW and the Willys-Overland-built MB is consistent with the standardized military specification design that governed production of both vehicles during the 1941-1945 period.
