Additional Notes

  • The Fenwick Forklift trucks, diesel (023 series) powershift transmissions carry either 42 or 46 liters of automatic transmission fluid, depending on the engine variant fitted to the machine.
  • Models equipped with the Scania DS11 66A engine — the H320, H370, and H420 — share an identical transmission fluid capacity of 42 liters under normal use conditions.
  • The H450 and H520, both fitted with the Scania DS11 59A engine, require 46 liters of automatic transmission fluid, representing a 4-liter increase over the DS11 66A-equipped models.
  • A 42- or 46-liter capacity is consistent with a large industrial powershift transmission, where fluid volume serves both hydraulic actuation and thermal management functions across heavy-duty operating cycles.
  • All five configurations share a fluid level check interval of every 10 operating hours, reflecting the critical role of fluid level monitoring in powershift transmission reliability.
  • The fluid change interval across all listed configurations is set at 1000 operating hours under normal use conditions, applying uniformly regardless of which Scania engine variant is installed.
  • In industrial forklift applications, operating hours rather than calendar time or distance are the standard basis for service intervals, since machine usage intensity varies considerably between sites.
