Iseki SX

Power steering fluid capacity & service interval

Iseki SX power steering fluid capacity ranges from 0,5 to 3,3 liters. Service intervals include checking at 100 hours and changing at 300 hours. The data covers 4 configurations.

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

Additional Notes

  • The Iseki SX power steering system holds 3.3 liters, a capacity typical of a hydraulic power steering circuit that includes a reservoir, pump, and associated lines rather than a simple gearbox fill.
  • The steering box on both the SX 75 and SX 95 carries a separate 0.5-liter capacity, reflecting a self-contained gearbox lubricant fill independent of the main power steering circuit.
  • A check interval of 100 hours applies to both the power steering system and the steering box across the SX 75 and SX 95, meaning fluid level and condition inspections are due at the same frequency for both components.
  • The power steering fluid change interval is set at 300 hours under normal use conditions, placing the drain-and-refill service at three times the frequency of the 100-hour check interval.
  • The steering box specification lists only a check interval of 100 hours with no corresponding change interval, meaning the service schedule for that component is limited to inspection rather than periodic replacement.
  • The SX 75 and SX 95 share identical capacity and interval figures for both the power steering system and the steering box, indicating no variation in fluid service specifications between the two models within the 1988-1992 period.
