Additional Notes

  • The Komatsu WF450-3 and WF450T-3 share an identical differential fluid capacity of 65 liters for both the front and rear differentials, each of which is a limited slip type.
  • The WF550-3 and WF550T-3 carry a notably larger differential capacity of 95 liters per axle, front and rear, reflecting the greater size and load demands of the 550-series compactors compared to the 450-series.
  • All eight rows across the 2000-2003 model range are rated under normal use conditions, meaning the listed capacities apply to standard operating environments rather than severe-duty cycles.
  • The parenthetical notation "+ hub reductions" on every capacity figure indicates that the 65-liter and 95-liter values cover only the differential housing itself. The planetary hub reduction units at each wheel end hold additional fluid volume not included in those figures.
  • Limited slip differentials, as specified across all four models, require fluid formulated to be compatible with the friction modifier demands of limited slip clutch packs. Using a standard gear oil without the appropriate additive package can cause chatter or premature wear in limited slip units.
  • The T-suffix variants, WF450T-3 and WF550T-3, carry the same differential capacities as their non-T counterparts within the same size class, with 65 liters for the 450T-3 and 95 liters for the 550T-3.
