Additional Notes

  • The Fenwick Forklift trucks, diesel (358 series) equipped with the Perkins 1006.60T engine carries a powershift transmission fluid capacity of 19.5 liters across the H120/1200, H140/1200, H160, and H160/1200 variants, all sharing identical fill volume.
  • A 19.5-liter capacity in a powershift transmission is a substantial fill volume, consistent with heavy-duty industrial equipment where the transmission housing integrates torque converter circuits, clutch packs, and hydraulic control passages that collectively demand a large fluid reservoir.
  • The fluid check interval is set at 10 hours of operation under normal use conditions, a very short cycle that reflects the demanding duty cycles typical of forklift applications, where frequent load cycling generates heat and places continuous stress on transmission fluid.
  • The fluid change interval is specified at 1000 hours under normal use conditions, a time-based metric common in industrial machinery where calendar time is less meaningful than actual machine operating hours as a measure of fluid degradation.
  • All four variants in the 358-01 series share the same 19.5-liter capacity, 10-hour check interval, and 1000-hour change interval, indicating a uniform powershift transmission design across the H120/1200, H140/1200, H160, and H160/1200 configurations despite differences in load ratings suggested by their model designations.
