Additional Notes

  • The front differential on the Goldoni Boxster series carries a fluid capacity of 1.35 liters, a figure consistent with a compact tractor front axle housing rather than a larger drivetrain assembly requiring multiple liters.
  • Both the Boxster 20 with the Yanmar 3TNV70 engine and the Boxster 25 with the Yanmar 3TNV76 engine share an identical front differential fluid capacity of 1.35 liters, indicating no variation in axle housing volume between the two configurations despite differing engine displacements.
  • The fluid check interval for the front differential is set at 50 hours of operation under normal use conditions, a relatively short interval that reflects routine inspection rather than a full fluid exchange.
  • The fluid change interval for the front differential is specified at 800 hours under normal use conditions, representing a long-term service milestone compared to the more frequent 50-hour check cycle.
  • The ratio between the check interval and the change interval, 50 hours versus 800 hours, means the fluid level and condition are inspected sixteen times before a full drain and refill is due under normal operating conditions.
