Additional Notes

  • The Case-IH 40 series cooling system capacity varies by model, ranging from 14.1 liters on the 440, 540, and 640 up to 17.5 liters on the 740 and 18.5 liters on the 840 and 940, reflecting differences in engine displacement and thermal load across the lineup.
  • The 440, 540, and 640 share an identical 14.1-liter cooling system capacity, indicating a common engine cooling architecture across those three variants.
  • The 740 carries a 17.5-liter cooling system capacity, placing it between the smaller 14.1-liter group and the larger 18.5-liter group, consistent with a mid-range engine configuration.
  • The 840 and 940 both specify an 18.5-liter cooling system capacity, the largest in the series, which corresponds to higher-output engine installations requiring greater coolant volume for heat dissipation.
  • Across all six variants, the coolant check interval is set at 50 operating hours under normal use conditions, a relatively frequent interval that reflects the importance of monitoring coolant level and condition in heavy-duty agricultural equipment.
  • The coolant change interval is 1,200 hours for all variants under normal use conditions. At typical agricultural usage rates, 1,200 hours can represent several seasons of operation, making adherence to hour-based tracking more relevant than calendar-based scheduling.
  • The 440 and 940 are listed with a 1991-1992 year range, while the 540, 640, 740, and 840 carry a 1991 start year, meaning the specifications for the latter four models apply from 1991 onward within the scope of the data provided.
