Iseki TD

Differential fluid capacity & service interval

Iseki TD differential fluid capacity ranges from 6 to 12 liters. Service intervals include checking at 100 hours and changing at 300 or 900 hours. The data covers 2 configurations.

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

  • TD 4451 TE, FE (1986-1992)
  • Front
  • Use: Normal
  • Capacity 6 liter
  • Check 100 hours
  • Change 900 hours
  • Code: (4x4)

Additional Notes

  • The Iseki TD 4411 TE and FE front differential carries a capacity of 12 liters, which is a notably large fill volume for a front differential and reflects the demands of a full overhaul or complete drain-and-refill service rather than a partial top-up.
  • The TD 4411 TE and FE front differential service interval under normal use conditions is set at 300 hours, meaning fluid replacement is due at that operating hour threshold.
  • The TD 4451 TE and FE front differential holds 6 liters, exactly half the capacity of the TD 4411 TE and FE, indicating a meaningfully different differential assembly between the two models despite sharing the same production years of 1986-1992.
  • The TD 4451 TE and FE front differential service schedule under normal use conditions includes a fluid level check at 100 hours, which occurs well before the full fluid change interval of 900 hours, allowing for early detection of fluid loss or contamination without a complete service.
  • The 900-hour change interval on the TD 4451 TE and FE front differential is three times longer than the 300-hour change interval on the TD 4411 TE and FE, representing a substantial difference in scheduled maintenance frequency between the two configurations.
