Additional Notes

  • The Case-IH 33 series manual transaxle fluid capacity ranges from 34 to 36 liters depending on the model variant, which reflects the physical size differences between transaxle housings across the lineup.
  • The 433, 533, and 633 share a 36-liter transaxle capacity under normal use conditions, while a separate 633 specification lists 34 liters, indicating two distinct transaxle configurations exist within the 633 model designation.
  • The 733 and 833 both carry a 34.5-liter transaxle capacity under normal use conditions, placing them between the two 633 capacity figures.
  • A fluid level check interval of 200 hours applies uniformly across all six rows, meaning routine inspection is scheduled well before the full drain cycle regardless of model variant.
  • The fluid change interval is set at 1600 hours across all listed configurations under normal use conditions, representing a long-cycle maintenance schedule typical of agricultural equipment operating in controlled workloads.
  • The ratio between the check interval and the change interval is 1:8, meaning eight fluid level inspections are expected to occur before a single drain-and-fill service is due on any of the listed variants.
