Dronningborg (Case IH) All models

Manual transmission fluid capacity & service interval

Dronningborg (Case IH) All models use manual transmission fluid with a capacity range of 3,5 to 6,5 liters. Service intervals occur every 500 hours or 24 months. The data covers 7 configurations.

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

Additional Notes

  • Across the Dronningborg (Case IH) lineup from 1982-1990, the manual transmission fluid system is a transaxle configuration, meaning the transmission and drive axle share a common housing and, in these specifications, a common fluid fill.
  • The D 4000S, D 4500, and D 7500 models all carry a transaxle capacity of 3.5 liters, regardless of whether the engine fitted is a Perkins or Valmet unit. The shared capacity across different engine pairings indicates the transaxle assembly itself is consistent across those model variants.
  • The D 8500 carries a notably larger transaxle capacity of 6.5 liters, nearly double the 3.5-liter figure specified for the D 4000S, D 4500, and D 7500. A larger transaxle volume of this kind is typical of heavier or higher-torque machinery where the drivetrain components are physically larger and require greater fluid volume to maintain adequate lubrication.
  • The 3.5-liter capacity listed for the D 4000S with both the Perkins 4.236 and the Valmet D411 engine reflects a service fill level. In transaxle systems, service fill capacity is the volume required when refilling during a routine fluid change, as opposed to a dry or overhaul fill which would account for residual fluid in passages and components.
  • The change interval for all listed models is 500 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger format, combining an operating-hour threshold with a calendar-based limit, accounts for machines that accumulate hours slowly and might otherwise go extended periods without a fluid change.
  • The 500-hour interval applies uniformly across all engine and model combinations in the 1982-1990 range, from the smaller D 4000S to the larger D 8500, with no variation tied to engine make or displacement.
  • The use condition specified for all rows is normal, meaning the 500-hour/24-month interval is not a reduced severe-duty schedule. In agricultural machinery contexts, a normal-use classification typically assumes operation within standard load and temperature ranges rather than continuous maximum-load or extreme-environment conditions.
