Additional Notes

  • All four WF-3 series compactors covered here use powershift transmissions, a type of automatic gearbox common in heavy construction equipment that allows gear changes under full load without interrupting power delivery to the drivetrain.
  • The Komatsu WF450-3 and WF450T-3 share an identical automatic transmission fluid capacity of 60 liters, indicating the same powershift transmission unit is used across both the standard and T-variant configurations in the 2000-2003 production run.
  • The WF550-3 and WF550T-3 each carry a 62-liter capacity, two liters more than the WF450-series equivalents, reflecting the larger powershift transmission assembly associated with the higher-rated 550 platform.
  • A 60- to 62-liter fluid volume is characteristic of a full service fill for a heavy-duty powershift transmission, meaning the figure accounts for fluid retained throughout the entire transmission circuit, including the torque converter, clutch packs, and internal passages, rather than just a sump drain quantity.
  • All four rows carry a normal use condition designation, meaning the stated capacities apply to standard operating environments rather than severe-duty cycles such as extreme temperatures or continuous high-load operation.
  • The T-suffix variants, WF450T-3 and WF550T-3, share their respective transmission fluid capacities exactly with their non-T counterparts, suggesting the T designation reflects a difference in another system or configuration rather than a change in the powershift transmission itself.
