Additional Notes

  • All three 4x4 configurations in the Mercedes-Benz Atego Euro 3 (EU) lineup share an identical transfer case fluid capacity of 5.5 liters, which represents a service fill volume for the transferbox rather than a full overhaul quantity.
  • The 12-month change interval applies under normal use conditions across the 1018 AK, 1318 AK, and 1523 AK variants, meaning fluid renewal is tied to a calendar-based schedule rather than a mileage or hour threshold.
  • The Atego 1018 AK 4x4 Euro 3 covers the widest model year span among the three, running from 2001-2006, while the 1318 AK and 1523 AK both entered the specification from 2003-2006.
  • A 5.5-liter transfer case capacity is a moderately substantial fill volume, consistent with a multi-axle drive unit designed for light-to-medium commercial truck applications rather than a compact passenger vehicle transfer case.
  • The uniform 5.5-liter capacity across all three configurations suggests the same transferbox unit is fitted regardless of the gross vehicle weight rating differences implied by the 1018, 1318, and 1523 model designations.
