Additional Notes

  • The front differential on the Fenwick Forklift trucks, diesel (023 series) H320 variant holds 28 liters, a notably smaller capacity compared to the 38 liters specified across all other variants in the lineup.
  • The H370, H420, H450, and H520 variants all share an identical front differential capacity of 38 liters, despite spanning two different Scania engine designations, the DS11 66A and the DS11 59A.
  • A fluid level check interval of 250 hours under normal use conditions applies uniformly across all five variants, from the H320 through the H520.
  • The fluid change interval is set at 2000 hours under normal use conditions for every variant listed, meaning a single change cycle represents eight times the duration of a single check interval.
  • The DS11 66A engine is paired with the H320, H370, and H420 variants, while the DS11 59A engine appears in the H450 and H520 variants, yet both engine families share the same check and change intervals for the front differential.
  • All five variants carry a starting year of 1995, placing the entire 023 series differential fluid specification within the same model year introduction point.
