Steyr Multitrac/Kommunal 900

Differential fluid capacity & service interval

Steyr Multitrac/Kommunal 900 uses differential fluid with a capacity range of 4,5 to 5 liters. Service intervals include checking every 250 hours and changing every 1000 hours or 24 months. The data covers 4 configurations.

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

Additional Notes

  • The Steyr Multitrac/Kommunal 900 series front differential fluid capacity falls into one of two values across the four listed configurations: 5 liters for the M952a/KM952a and M963a/KM963a, and 4.5 liters for the M968/M968a/KM968a and M975a/KM975a.
  • A 5-liter front differential capacity is specified for the M952a and KM952a variants introduced from 1998, reflecting the fill volume required to bring the front differential to its correct operating level.
  • The M963a and KM963a share the same 5-liter front differential capacity as the M952a and KM952a, indicating a common differential assembly across those two configurations.
  • The M968, M968a, and KM968a carry a slightly reduced front differential capacity of 4.5 liters, a 0.5-liter difference from the M952a and M963a families, which points to a physically distinct differential unit in the M968 line.
  • The M975a and KM975a also specify a 4.5-liter front differential capacity, aligning with the M968 group rather than the 5-liter configurations.
  • All four configurations share an identical check interval of 250 hours under normal use conditions, meaning the fluid level in the front differential is to be verified at that frequency regardless of the specific variant.
  • The change interval across all listed configurations is 1000 hours or 24 months under normal use conditions, whichever comes first, applying uniformly to both the 5-liter and 4.5-liter differential groups.
  • The dual-format change interval of 1000 hours and 24 months means that calendar time serves as an independent trigger for fluid replacement, relevant in lower-utilization applications where the hour threshold may not be reached within two years.
