Logset Forwarders

Differential fluid capacity & service interval

Logset Forwarders require differential fluid with a capacity range of 11 to 12 liters. Service intervals occur every 2000 hours. The data covers 8 configurations.

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

Additional Notes

  • The Logset 4F forwarder carries 11 liters of differential fluid in each axle, front and rear, for a combined differential fluid volume of 22 liters across both housings.
  • The Logset 5F, 6F, and 8F forwarders each specify 12 liters per differential, front and rear, placing each of those models at a combined 24 liters across both axle housings.
  • The step from 11 liters on the 4F to 12 liters on the 5F reflects the larger axle assemblies used in the higher-capacity forwarder models, where greater load-bearing demands require proportionally larger differential housings.
  • All listed forwarder models share a uniform differential fluid change interval of 2000 operating hours under normal use conditions, applying equally to both the front and rear differentials on every model.
  • A 2000-hour service interval is a common benchmark in heavy forestry equipment, corresponding roughly to one to two seasons of intensive field operation depending on annual machine utilization.
  • The front and rear differential capacities are identical on every listed model, indicating symmetrical axle designs where both housings are engineered to the same specification within each model variant.
  • The 5F, 6F, and 8F models share the same 12-liter per differential capacity despite representing different size classes, suggesting the axle hardware used across those three models is dimensionally consistent in terms of fluid volume.
