Additional Notes

  • The PW98MR-6 transfer case holds 1.5 liters of fluid, a relatively small capacity consistent with a compact transfer box unit in a wheeled excavator of this class.
  • The 250-hour interval applies to a fluid level check under normal use conditions, meaning the transfer box is inspected for proper fill without a full drain and replacement at that point.
  • The full fluid change interval for the Komatsu PW98MR-6 transfer case is set at 1,000 hours under normal use conditions, placing the drain-and-refill service well beyond the routine check interval.
  • The gap between the 250-hour check and the 1,000-hour change means the transfer box fluid level is verified four times before a complete fluid replacement is due under normal operating conditions.
