Valpadana 6400 Series

Differential fluid capacity & service interval

Valpadana 6400 Series requires differential fluid with a capacity of 3,3 liters. Service intervals occur every 1000 hours or 12 months. The data covers 6 configurations.

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

Additional Notes

  • All six configurations in the Valpadana 6400 Series share an identical front differential fluid capacity of 3.3 liters, indicating a uniform front axle housing design across the range regardless of engine or transmission variant.
  • The 3.3-liter figure represents a service fill capacity, which is the volume required when draining and refilling the differential during a scheduled fluid change rather than a full overhaul or assembly fill.
  • The change interval is specified at 1,000 hours or 12 months under normal use conditions, meaning whichever threshold is reached first triggers the required service.
  • The dual-trigger interval structure, combining an engine-hour threshold with a calendar-based limit, reflects the reality that low-utilization machines may reach the time limit before accumulating sufficient operating hours.
  • The 6450 and 6460 variants are paired with the Yanmar 4TNV88-KVA engine, while the 6475 variants use the John Deere 4024 HF295 engine, yet both engine pairings share the same 3.3-liter front differential capacity and 1,000-hour/12-month interval.
  • Within each engine family, the ISM and VRM transmission designations produce no variation in front differential capacity or service interval, placing the specification difference between those variants outside the differential system entirely.
  • All specifications apply to the front differential specifically, which in a tractor context refers to the fluid housing within the front axle assembly that manages torque distribution to the front wheels when four-wheel drive is engaged.
