Additional Notes

  • The WB93R-2 equipped with the Komatsu S4D106-2SFA engine carries a 16-liter automatic transmission fluid capacity for its powershift transmission under normal use conditions.
  • A 16-liter fill volume is characteristic of a powershift transmission, which uses hydraulic pressure and fluid coupling to shift gears without interrupting power flow, requiring a relatively large fluid reservoir to maintain consistent hydraulic function.
  • The normal use condition tied to the 16-liter specification indicates a standard operating environment, as opposed to severe-duty cycles that would typically involve more demanding drain and refill schedules.
