New Holland T4S

Differential fluid capacity & service interval

New Holland T4S differential fluid capacity is 6 liters. Service intervals include checking at 300 hours and changing at 1200 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 New Holland T4S front differential holds 6 liters across the T4.55S, T4.65S, and T4.75S variants, a capacity figure that reflects a service fill rather than a full overhaul volume.
  • All three variants share an identical check interval of every 300 hours under normal use conditions, which is a periodic inspection point rather than a full fluid exchange.
  • The change interval is set at 1200 hours or 24 months, whichever comes first, meaning time elapsed can trigger a fluid change even when the hour threshold has not been reached.
  • The 1200-hour change interval applies specifically to normal use conditions, as opposed to severe-duty cycles that typically demand shorter drain intervals on comparable equipment.
  • The uniform 6-liter capacity across the T4.55S, T4.65S, and T4.75S suggests a shared front differential housing design despite the differing power ratings among the three variants.
  • The ratio of the check interval to the change interval is 1:4, meaning the fluid level is inspected at 300, 600, 900, and 1200 hours before a full change is due within a single service cycle.
