Doppstadt Trac

Power steering fluid capacity & service interval

Doppstadt Trac uses power steering fluid with a capacity range of 35 to 60 liters. Service intervals include a check every 10 hours and a change every 500 hours or 12 months. The data covers 2 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, starting from 2000, carries a hydraulic system and power steering fluid capacity of 35 liters, while the Systra mechanical drive variant of the same model holds 60 liters — a difference of 25 liters between the two drivetrain configurations.
  • The 60-liter capacity on the mechanical drive variant is notably larger than the hydrostatic drive's 35 liters, reflecting the greater fluid volume demands of a mechanical hydraulic circuit compared to a hydrostatic one.
  • Both drivetrain configurations share an identical check interval of every 10 hours of operation, indicating a frequent monitoring requirement consistent with heavy-duty machinery hydraulic systems.
  • The change interval for both the hydrostatic and mechanical drive variants is set at 500 hours or 12 months, whichever comes first, applying under normal use conditions.
  • The dual-trigger change interval — 500 hours or 12 months — means that even in low-usage scenarios where 500 operating hours are not reached within a year, a fluid change is still due at the 12-month mark.
