Additional Notes

  • The Claas Dominator 108 Classic carries a combined transmission and hydrostatic fluid capacity of 17 liters, more than double the 8-liter figure shared by every other variant in the 1991-1999 range. A larger reservoir in a hydrostatic drive system generally supports greater heat dissipation and sustained hydraulic pressure under heavy load conditions.
  • The Dominator 108 Maxi SL and Classic SL share an 8-liter transmission and hydrostatic capacity despite carrying the same model number as the Classic. The difference in capacity between the 108 Classic and the 108 SL variants indicates a fundamentally different hydrostatic drive configuration between those two lines.
  • The Dominator 78 SL Classic, 88 SL Classic, 98 SL Classic, 98 SL Maxi, and 118 Maxi SL all specify an identical 8-liter capacity for the combined transmission and hydrostatic system. Uniform capacity across a wide spread of model designations points to a common hydrostatic unit used throughout the SL-series lineup during the 1991-1999 period.
  • All seven variants list a normal use condition for the transmission and hydrostatic fluid specification. In service interval contexts, a normal use designation typically reflects standard operating cycles rather than the more demanding duty cycles associated with severe use ratings.
  • The hydrostatic note applied to every row indicates the fluid capacity covers both the mechanical transmission and the hydrostatic drive circuit together as a shared system, rather than as two separately serviced volumes.
