Terex Fuchs Wheeled excavators, MHB

Differential fluid capacity & service interval

Terex Fuchs Wheeled excavators, MHB differential fluid capacity ranges from 10,8 to 20,5 liters. Service intervals include 100, 1000, and 2000 hours for changes, plus 500 hours for checks. The data covers 12 configurations.

Additional Notes

  • The Terex Fuchs MHB230, MHB230C, and MHB230CS share identical front differential capacity of 10.8 liters and an identical rear differential capacity range of 11.2–13.8 liters, with all positions on a 2000-hour change interval under normal use conditions.
  • The rear differential capacity listed as a range of 11.2–13.8 liters across the MHB230, MHB230C, and MHB230CS reflects variation in fill volume, which in differential service typically corresponds to differences in axle configuration or drain-and-refill versus full overhaul fill procedures.
  • The MHB230ZW carries substantially larger differential capacities than the MHB230 variants, with a front differential holding 14.5 liters and a rear differential holding 20.5 liters, both on the same 2000-hour change interval under normal use conditions.
  • The MHB230ZW rear differential capacity of 20.5 liters is notably higher than the rear differential figures for all other MHB230-series variants, indicating a heavier-duty or differently configured axle assembly in the ZW model.
  • The MHB240 and MHB250 rigid axle differentials each hold 11 liters and follow a two-stage service schedule under normal use conditions: a fluid level check at 500 hours, followed by a full fluid change at 1000 hours or 12 months, whichever comes first.
  • Both the MHB240 and MHB250 include an initial service interval requiring a differential fluid change at 100 hours. An early change at this interval is standard practice for new or rebuilt gear assemblies, as it removes metal particles generated during the break-in period.
  • The MHB240 and MHB250 share identical rigid axle differential specifications across capacity, check interval, change interval, and initial service interval, with no variation between the two models in any of those values.
  • The 2000-hour change interval applied to all MHB230-series differentials is twice the 1000-hour change interval specified for the MHB240 and MHB250 rigid axle differentials, representing a meaningful difference in service frequency between the two model groups.
