Mercedes-Benz T2 (EU)

Transfer case fluid capacity & service interval

Mercedes-Benz T2 (EU) transfer case fluid capacity ranges from 0,8 to 5,6 liters. Service intervals include a check at 10000 km and a change at 20000 km. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
809 D/DT (1986-1996)
  • Use: Normal
  • Capacity 0,8 liter
  • Check 10000 km
  • Change 20000 km
814 D/DA (1986-1996)
  • Use: Normal
  • Capacity 5,6 liter
  • Check 10000 km
  • Change 20000 km

Additional Notes

  • The 809 D/DT transfer case holds 0.8 liter of fluid, a notably small capacity that reflects a compact transfer unit typical of lighter-duty drivetrain configurations.
  • The 814 D/DA carries a transfer case capacity of 5.6 liters, which is seven times greater than the 809 D/DT figure, indicating a substantially larger transfer unit suited to heavier load demands.
  • Both the 809 D/DT and 814 D/DA share identical service intervals under normal use conditions, with a fluid level check specified at every 10,000 km and a full fluid change at every 20,000 km.
  • The Mercedes-Benz T2 (EU) transfer case intervals listed here apply specifically to normal use conditions, meaning the 10,000 km check and 20,000 km change figures are not rated for more demanding operating environments.
  • The 20,000 km change interval is relatively short by modern standards, which is consistent with the maintenance expectations of commercial vehicle transfer cases from the 1986-1996 production period.
  • The 10,000 km check interval, set at half the drain interval, reflects a practice of monitoring fluid condition and level between full changes rather than relying solely on mileage-based replacement alone.
