Valtra (Valmet) N5 Active

Differential fluid capacity & service interval

Valtra (Valmet) N5 Active differential fluid capacity is 7,5-8 liters. Service intervals include checks at 600 hours and changes at 1200 hours or 12 months. The data covers 4 configurations.

Additional Notes

  • The Valtra (Valmet) N5 Active front differential capacity is listed as a range of 7.5 to 8 liters across all four variants — the N135, N155, N155E, and N175 Active. A capacity expressed as a range rather than a fixed value typically accounts for minor variation depending on fill angle, temperature, or residual fluid left during a drain.
  • All four variants share an identical check interval of 600 hours under normal use conditions, meaning the fluid level is inspected at that point without a full drain and refill being required.
  • The change interval for the front differential fluid is set at 1200 hours or 12 months, whichever comes first, under normal use conditions. The dual-trigger format — combining an hour-based threshold with a calendar-based one — reflects that agricultural equipment may accumulate operating hours unevenly across seasons.
  • The check interval at 600 hours falls at exactly the halfway point of the 1200-hour change interval, which positions it as a midpoint inspection rather than an independent service event tied to a separate schedule.
  • The N155E Active carries the same 7.5 to 8 liter front differential capacity and the same 600-hour check and 1200-hour/12-month change intervals as the standard N155 Active, indicating no differentiation in differential service requirements between those two variants despite the "E" designation.
