Iseki TD

Power steering fluid capacity & service interval

Iseki TD power steering fluid capacity is 2 liters. Service intervals include checking at 100 hours and changing at 300 hours. The data covers 2 configurations.

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

  • Change 300 hours
TD 4451 TE, FE (1986-1992)
  • Use: Normal
  • Capacity 2 liter
  • Check 100 hours
  • Change 300 hours

Additional Notes

  • The Iseki TD 4411 and TD 4451 each carry a power steering fluid capacity of 2 liters, which represents the working system volume rather than a full hydraulic overhaul fill.
  • Both the TE and FE variants of the TD 4411 share identical power steering fluid specifications, with no differentiation between trim levels in the 1986-1992 production span.
  • The same holds for the TD 4451, where TE and FE variants are assigned the same 2-liter capacity, 100-hour check interval, and 300-hour change interval under normal use conditions.
  • A 100-hour check interval on both models reflects a periodic inspection point, not a fluid replacement, allowing the system level and condition to be monitored between full changes.
  • The 300-hour change interval applies under normal use conditions, meaning operating environments outside of normal parameters could warrant a different service schedule not reflected in these specifications.
  • Across both the TD 4411 and TD 4451, the ratio of check interval to change interval is 1:3, meaning three fluid level checks are expected to occur for every full fluid replacement cycle.
