Doppstadt Trac

Transfer case fluid capacity & service interval

Doppstadt Trac transfer case fluid capacity ranges from 0,9 to 6,7 liters. Service intervals consist of a 500 hour check and a 1000 hour change. The data covers 3 configurations.

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

Additional Notes

  • The Doppstadt Trac 80 with Systra hydrostatic drive carries a transfer case fluid capacity of 6.7 liters, a figure associated with the main transferbox as a standalone unit.
  • A separate front transferbox/p.t.o. compartment on the Trac 80 Systra hydrostatic drive holds 0.9 liters, indicating a distinct, smaller reservoir serviced independently from the main transferbox.
  • The Trac 80 with Systra mechanical drive shares the same 0.9-liter capacity for the front transferbox/p.t.o. as the hydrostatic variant, despite the differing drivetrain architecture.
  • Across all three listed configurations, the fluid check interval is set at 500 hours under normal use conditions, with a full fluid change required at 1,000 hours under the same conditions.
  • The 500-hour check interval serves as a midpoint inspection before the 1,000-hour change, allowing for fluid level and condition monitoring without a full drain-and-refill procedure.
  • All specifications apply to normal use conditions, meaning the 500-hour check and 1,000-hour change intervals are not adjusted for severe operating environments in the listed data.
