International Harvester 44

Brake fluid capacity & service interval

International Harvester 44 requires brake fluid with a capacity of 0,5 liter. Service intervals include checks at 50 hours and changes at 1000, 1500, and 1600 hours. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

  • Change 1600 hours

Additional Notes

  • The hydraulic brake system capacity across all four configurations — the 644, 744, 844 S, and 844 XL — is 0.5 liter, a figure consistent with a service fill rather than an overhaul volume.
  • The International Harvester 44 series brake fluid check interval is set at 50 hours across all listed configurations, applying under normal use conditions.
  • The 644 (1975-1980) and 744 (1975-1980) share an identical change interval of 1500 hours under normal use conditions.
  • The 844 S (1974-1985) carries the longest change interval among the listed configurations at 1600 hours under normal use conditions, 100 hours beyond the 644 and 744 figures.
  • The 844 XL (1981-1985) has a change interval of 1000 hours under normal use conditions, the shortest among the four configurations and 600 hours less than the 844 S.
  • The 844 S and 844 XL share the same model designation base yet differ by 600 hours in their brake fluid change intervals, indicating a specification distinction between the two trim levels despite identical capacity and check interval values.
