Iseki SX

Differential fluid capacity & service interval

Iseki SX differential fluid capacity ranges from 15 to 16 liters. Service intervals consist of checks every 100 hours and changes every 300 hours. The data covers 2 configurations.

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

Additional Notes

  • The Iseki SX 75 front differential holds 15 liters, while the SX 95 front differential holds 16 liters, reflecting a one-liter difference between the two models across the 1988-1992 range.
  • A 15-liter or 16-liter differential capacity is characteristic of a full service fill, meaning the volume required to bring the differential to its operational fluid level during routine servicing rather than a complete overhaul drain-and-refill.
  • Both the SX 75 and SX 95 share a 300-hour front differential fluid change interval under normal use conditions.
  • The SX 75 specifications include a fluid check interval at 100 hours, which falls between service changes and serves as an intermediate inspection point to verify fluid level and condition before the 300-hour change is due.
  • The SX 95 specifications do not carry a separate check interval entry, meaning only the 300-hour change interval is recorded for that model's front differential.
  • Both models apply normal use conditions to the front differential service intervals, meaning the 300-hour change schedule is not adjusted for severe operating environments in the listed specifications.
