Valtra (Valmet) N5 Direct

Differential fluid capacity & service interval

Valtra (Valmet) N5 Direct 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) N5 Direct front differential capacity is listed as a range of 7.5 to 8 liters across all four variants — the N135, N155, N155E, and N175 Direct — rather than a single fixed value, which reflects a typical service fill tolerance rather than a precise overhaul measurement.
  • The N135 Direct, N155 Direct, N155E Direct, and N175 Direct all share an identical front differential check interval of 600 hours under normal use conditions.
  • The fluid change interval for the front differential is set at 1,200 hours or 12 months, whichever comes first, applying uniformly across all four variants under normal use conditions.
  • The 600-hour check interval falls at exactly half the 1,200-hour change interval, meaning one inspection cycle occurs between each fluid change.
  • Despite the N155E Direct representing a distinct variant from the N155 Direct, both share the same 7.5 to 8 liter front differential capacity and the same 1,200-hour or 12-month change interval under normal use conditions.
  • All four variants carry a 2021 starting year, and the front differential specifications — capacity, check interval, and change interval — are consistent across the entire N5 Direct lineup for that model year.
