Valtra (Valmet) N4 Active

Differential fluid capacity & service interval

Valtra (Valmet) N4 Active differential fluid capacity is 7,5-8 liters. Service intervals include checking at 600 hours and changing at 1200 hours or 12 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 Valtra (Valmet) N4 Active front differential capacity is listed as a range of 7.5 to 8 liters across all four variants, which reflects a typical service fill tolerance rather than a fixed overhaul volume, allowing for minor variation during draining and refilling procedures.
  • The N134 Active, N154 Active, N154e Active, and N174 Active all share an identical front differential capacity specification of 7.5 to 8 liters, indicating a common axle assembly across the N4 Active lineup for the 2015-2021 period.
  • A check interval of 600 hours applies to the front differential on all four variants under normal use conditions, meaning fluid level and condition are to be inspected at that point before the full change interval is reached.
  • The change interval for the front differential fluid is set at 1200 hours or 12 months under normal use conditions, whichever comes first, combining both an operational hour threshold and a calendar-based limit.
  • The dual-trigger change interval of 1200 hours or 12 months means that a tractor accumulating low annual hours would still reach the service point based on elapsed time alone, while a high-utilization machine would reach it on hours first.
  • All four variants — N134, N154, N154e, and N174 — carry the same check and change intervals for the front differential, with no variation in service timing across the engine displacement or power output differences represented by those model designations.
