Eicher 600 (VC/VAC)

Differential fluid capacity & service interval

Eicher 600 (VC/VAC) differential fluid capacity is 4 liters. Service intervals include checking every 200 hours and changing every 1000 hours or 12 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 Eicher 600 (VC/VAC) series front differential holds 4 liters of fluid across the 656 VAC, 666 VAC, and 680 VAC configurations for the 2000-2004 model years.
  • A 4-liter front differential capacity is a service fill figure, meaning the volume expected during a standard drain-and-refill procedure rather than a full overhaul or housing replacement.
  • Under normal use conditions, the front differential fluid on the 656 VAC, 666 VAC, and 680 VAC is subject to a check interval of 200 hours, which represents a relatively frequent inspection point relative to the full change interval.
  • The change interval for front differential fluid across all three VAC variants is set at 1000 hours or 12 months under normal use conditions, whichever comes first, combining an operational hour threshold with a calendar-based limit.
  • The 12-month calendar interval runs alongside the 1000-hour threshold, meaning a machine with low annual operating hours would still require a fluid change within a year under normal use conditions.
  • The front differential fluid specifications are identical across the 656 VAC, 666 VAC, and 680 VAC for the 2000-2004 period, with no variation in capacity, check interval, or change interval among the three variants.
