Additional Notes

  • The Bobcat E55W with Yanmar 4TNV98-E engine carries a transfer box fluid capacity of 1.5 liters, which applies to both the normal service fill and the initial service interval.
  • Under normal use conditions, the transfer box fluid check interval is set at 250 hours, meaning the fluid level is inspected at that point without a full drain and refill.
  • The normal use change interval for the transfer box fluid is defined by whichever threshold arrives first: 6 months or 1,000 hours of operation.
  • An initial service change is specified at 100 hours, which is a break-in interval separate from the ongoing normal use schedule and reflects the need to remove contaminants introduced during early mechanical wear-in.
