Steyr CVT (Kommunal)

Power steering fluid capacity & service interval

Steyr CVT (Kommunal) uses power steering fluid with a capacity of 51 liters. Service intervals include checking every 250 hours and changing every 1000 hours or 24 months. The data covers 3 configurations.

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

Additional Notes

  • The Steyr CVT (Kommunal) power steering system is part of a shared hydraulic circuit, as indicated by the "hydraulic system, power steering" note present across all three configurations — the CVT 120/KCVT 120, CVT 130/KCVT 130, and CVT 150/KCVT 150.
  • A 51-liter fluid capacity is specified uniformly across all three model variants. In agricultural and municipal machinery, a capacity of 51 liters for a combined hydraulic and power steering system reflects a large shared reservoir, typical of tractors where the hydraulic circuit serves multiple functions simultaneously.
  • The check interval is set at 250 hours across all variants. In hour-based service schedules common to tractors and municipal vehicles, a 250-hour check interval represents a routine inspection point rather than a full fluid replacement.
  • The change interval is specified as 1000 hours or 24 months, whichever comes first, for all three variants. The dual-condition format — combining an operational hour threshold with a calendar-based limit — accounts for machines that may accumulate hours slowly, ensuring fluid degradation over time is still addressed.
  • All three variants share identical capacity and interval specifications, meaning the CVT 120/KCVT 120, CVT 130/KCVT 130, and CVT 150/KCVT 150 show no variation in power steering fluid service requirements despite representing different power output levels within the same model family.
  • All specifications are listed under normal use conditions, meaning the 1000-hour/24-month change interval and 51-liter capacity apply specifically to standard operating circumstances rather than severe or demanding duty cycles.
