Additional Notes

  • The Case-IH 55/56 series manual transaxle fluid capacities span a notable range across configurations, from 31 liters in the smaller models up to 42.5 liters in the 856 XL Turbo and XLA Turbo variants.
  • The 1056 and 1056 XL, covering model years 1985-1992, share a 31-liter transaxle capacity with the 956 and 956 XL of the same production span, placing both pairs in the lowest capacity bracket within the series.
  • The 1255 XL and 1455 XL, both spanning 1985-1995, each carry a 40-liter transaxle fill, a figure that reflects the larger drivetrain housings associated with higher-output tractor configurations.
  • At 42.5 liters, the 856 XL Turbo and XLA Turbo hold the largest manual transaxle capacity across all listed configurations, a value consistent with the additional lubrication demands placed on turbocharged powertrain variants.
  • All five configurations share an identical service interval structure: a fluid level check at 200 operating hours and a full fluid change at 1,600 operating hours, both applied under normal use conditions.
  • The 200-hour check interval across all listed models serves as a periodic verification point rather than a fluid replacement event, allowing early detection of fluid loss or contamination between full change intervals.
  • A 1,600-hour change interval is a relatively extended service cycle by agricultural equipment standards, reflecting the large fluid volumes involved and the sealed nature of a manual transaxle housing in field-use machinery.
  • All specifications are designated for normal use conditions, meaning the 1,600-hour change interval applies to standard operating environments without adjustment for more demanding duty cycles.
