Ursus 02/04 series

Differential fluid capacity & service interval

Ursus 02/04 series requires differential fluid with a capacity of 3,5 liters. Service intervals include a check at 100 hours and a change at 800 hours. The data covers 4 configurations.

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

Additional Notes

  • Across all listed configurations of the Ursus 02/04 series, the front differential carries a fluid capacity of 3.5 liters, a value consistent with a service fill rather than a full overhaul quantity.
  • The 1002 and 1004 models, covering 1978-1985, share identical front differential specifications with the 902 and 904 models introduced in 1983-1985, including the same 3.5-liter capacity and interval schedule.
  • The 1454, produced from 1983-1985, and the 1604, produced from 1979-1985, both follow the same 3.5-liter front differential capacity as the other configurations in the series.
  • Under normal use conditions, the front differential fluid check interval is set at 100 hours across all listed models, indicating a relatively frequent monitoring schedule relative to the change interval.
  • The fluid change interval for the front differential is specified at 800 hours under normal use conditions, applying uniformly to all four model variants listed in the series.
  • The ratio between the check interval (100 hours) and the change interval (800 hours) means a fluid change occurs once for every eight scheduled checks under normal use conditions.
