Grove Cranes Mobile cranes

Transfer case fluid capacity & service interval

Grove Cranes mobile cranes utilize transfer case fluid with a capacity range of 8 to 15 liters. The data covers 5 configurations.

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

Additional Notes

  • The Grove Cranes GMK4080-2 and GMK4090, both powered by the Mercedes-Benz OM470LA engine from 2017, share an identical transfer case fluid capacity of 14 liters under normal use conditions.
  • The 14-liter transfer case capacity on the OM470LA-powered models reflects a mid-range fill volume typical of multi-axle all-terrain crane transfer boxes, where larger fluid volumes support sustained load distribution across multiple driven axles.
  • The GMK6300L and GMK6300L-1, both equipped with the Mercedes-Benz OM926LA engine from 2018, each carry a transfer case capacity of 15 liters under normal use conditions, the highest capacity figure among the configurations listed.
  • The 1-liter difference between the OM926LA-powered GMK6300L variants at 15 liters and the OM470LA-powered models at 14 liters corresponds to a difference in crane class, with the GMK6300L series representing a larger six-axle platform.
  • The Grove Cranes GMK6400, fitted with the Mercedes-Benz OM502LA engine from 2018, carries a transfer case capacity of only 8 liters under normal use conditions, notably lower than the other configurations in the same model year group.
  • The OM502LA is a V8 engine, while the OM470LA and OM926LA are inline-six units. The difference in engine architecture between the GMK6400 and the other models may relate to differing drivetrain layouts, which can influence transfer case design and fluid volume requirements.
  • All five configurations specify normal use conditions, meaning the listed capacities apply to standard operating environments rather than severe-duty cycles involving extreme temperatures, heavy off-road operation, or other demanding conditions.
  • All listed capacities are designated as transfer box fills, indicating service-level fluid volumes rather than overhaul or dry-fill figures, which are typically higher due to residual fluid retained in passages and components during a standard drain.
