Hürlimann H-300

Differential fluid capacity & service interval

Hürlimann H-300 uses differential fluid with a capacity range of 5 to 6 liters. Service intervals include checking at 150 hours and changing at 1200 hours. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Front differential fluid capacities across the Hürlimann H-300 series range from 5 liters to 6 liters depending on the model variant, with the H-356 (1984-1986) at the lower end and the H-358, H-358 Prestige, H-362, and H-372 at the higher 6-liter figure. These service fill volumes reflect the amount of fluid required during routine maintenance rather than a full overhaul, which would typically demand additional fluid to account for residual drainage and component displacement.
  • The H-351 (1987-1990) and H-361 (1987-1989) share an identical front differential capacity of 5.4 liters, placing them between the 5-liter H-356 and the 6-liter variants. Capacity differences of this kind in agricultural differentials generally correspond to variations in housing size or gear set dimensions tied to the power output of each model.
  • All six model variants share a uniform check interval of 150 operating hours under normal use conditions. In agricultural equipment, hour-based intervals are standard because engine load and field conditions vary widely, making calendar-based scheduling less reliable as a maintenance reference.
  • The change interval for front differential fluid is set at 1200 hours across all listed variants under normal use conditions. At typical seasonal usage rates for agricultural tractors, 1200 hours can represent several years of field operation, making the 150-hour check interval an important intermediate step to monitor fluid condition between full changes.
  • The H-358 and H-358 Prestige share the same 6-liter front differential capacity and identical service intervals, indicating that the Prestige trim designation did not alter the mechanical specification of the front differential assembly relative to the standard H-358.
  • The H-362 (1989-1994) and H-372 (1989-1994) carry the same 6-liter capacity and identical check and change intervals despite being distinct model designations. In tractor lines, shared differential specifications across adjacent models often reflect a common front axle platform used across a power range.
