Mercedes-Benz LK, 673 --> 679 (EU)

Transfer case fluid capacity & service interval

Mercedes-Benz LK, 673 to 679 (EU) models utilize transfer case fluid with a capacity of 4,5 liters. Service intervals include a check at 10000 km and a change at 40000 km. The data covers 2 configurations.

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

TypeSpecifications
914 AK (674.1) (1984-1995)
  • Use: Normal
  • Capacity 4,5 liter
  • Check 10000 km
  • Change 40000 km
917 (676) (1984-1995)
  • Use: Normal
  • Capacity 4,5 liter
  • Check 10000 km
  • Change 40000 km

Additional Notes

  • Both the 914 AK (674.1) and 917 (676) configurations carry a transfer case fluid capacity of 4.5 liters, which is a typical fill volume for a medium-duty transfer box of this era and reflects a service fill rather than a full overhaul quantity.
  • The check interval for the transfer case fluid is set at 10,000 km across both configurations, meaning the fluid level and condition are inspected at that mileage point without necessarily performing a full drain and refill.
  • The change interval is specified at 40,000 km under normal use conditions for both the 914 AK (674.1) and 917 (676), placing the drain-and-refill cycle at four times the frequency of the check interval.
  • The normal use condition tied to the 40,000 km change interval distinguishes standard operating environments from more demanding duty cycles, and both listed configurations share identical interval and capacity figures under that same condition.
  • The Mercedes-Benz LK 673-679 (EU) transfer case specifications apply consistently across the full 1984-1995 model year span for both the 914 AK (674.1) and 917 (676) variants, with no variation in capacity or service intervals recorded between those years.
