Steyr CVT (Kommunal)

Differential fluid capacity & service interval

Steyr CVT (Kommunal) differential fluid capacity ranges from 2,2 to 8 liters. Service intervals include checks at 250 and 500 hours, and changes at 1000 hours or 12 to 24 months. The data covers 12 configurations.

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

Additional Notes

  • The Steyr CVT (Kommunal) front differential without suspension carries a capacity of 8 liters across the CVT 120, CVT 130, CVT 150, and CVT 170 variants, indicating a substantial fluid volume consistent with a heavy-duty axle housing rather than a compact passenger vehicle differential.
  • Front differentials equipped with suspension are split across two separate capacity figures: 2.2 liters and 5.5 liters. The two values likely correspond to distinct sub-chambers or housings within the suspended front axle assembly, both of which require individual service attention.
  • The standard change interval across nearly all configurations is 1000 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger format means calendar time can mandate a fluid change even when hour accumulation remains low.
  • The check interval for nearly all configurations is set at 250 hours under normal use, meaning fluid level verification is required four times before a full change interval is reached at 1000 hours.
  • One notable deviation appears in the CVT 130 and KCVT 130 front differential with suspension at the 2.2-liter position. The check interval for that specific entry is 500 hours rather than the 250-hour figure seen elsewhere, and the change interval carries a 12-month calendar limit instead of 24 months, making the time-based threshold twice as frequent despite the same 1000-hour operational limit.
  • The shortened 12-month change interval on the CVT 130 and KCVT 130 suspended front differential at 2.2 liters suggests a more time-sensitive fluid degradation profile for that particular housing, independent of machine operating hours.
  • All specifications listed apply to normal use conditions. No severe-use intervals are defined in the data, meaning the figures above represent the baseline service schedule rather than a reduced-interval alternative.
