Reform Mounty

Differential fluid capacity & service interval

Reform Mounty uses differential fluid with a capacity of 3 liters. Service intervals include checking at 100 hours and changing at 600 hours or 24 months. The data covers 2 configurations.

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

Additional Notes

  • The Reform Mounty 65 front and rear differentials each carry a capacity of 3 liters, a figure that reflects a standard service fill rather than a full overhaul volume.
  • Both the front and rear differential service intervals share identical check and change schedules, with fluid checks due at 100 hours and full fluid changes required at 600 hours or 24 months, whichever comes first.
  • The 600-hour or 24-month change interval applies under normal use conditions, meaning operating environments outside of normal classification may warrant different service timing.
  • The time-based threshold of 24 months runs alongside the 600-hour mark as an independent trigger, so calendar time alone can initiate a fluid change even when hour meter readings remain below the operational limit.
  • The symmetry between front and rear differential capacities, both at 3 liters, indicates a mechanically balanced drivetrain design across the 2001-2010 Mounty 65 production span.
