Additional Notes

  • The Sampo Rosenlew FR28 differential holds 11.5 liters, a figure that reflects a standard service fill for the main differential housing rather than a full overhaul capacity.
  • The FR28 bogie axle differential carries 30 liters per unit, a notably higher capacity than the main differential, which is consistent with the larger fluid volume demands of a bogie axle assembly.
  • The FR48 main differential shares the same 11.5-liter capacity as the FR28, despite being a different model introduced in 2018.
  • The FR48 bogie axle differential holds 20 liters per unit, which is 10 liters less per axle than the FR28 bogie axle specification, indicating a structural difference between the two models' bogie assemblies.
  • All four configurations across both models share a uniform change interval of 2000 hours under normal use conditions, applying equally to both the main differential and the bogie axle differentials.
