Iseki TX/TXG

Differential fluid capacity & service interval

Iseki TX/TXG differential fluid capacity ranges from 0,7 to 4 liters. Service intervals include checking at 50 hours and changing at 50 or 300 hours. The data covers 11 configurations.

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

Additional Notes

  • Across the TX 1000, TX 1300, TX 1500, TX 2140F, and TX 2160F models covering 1978-1992, the front differential capacity is uniformly 0.7 liter, a figure consistent with the compact housing dimensions typical of small utility tractors in this class.
  • The 300-hour change interval applies under normal use conditions to all five TX-series models listed, meaning fluid replacement is tied to operating hours rather than a calendar period.
  • The Iseki TXG23, TXG237, and TXG237F3 each carry a front differential capacity of 4 liters, which is substantially larger than the 0.7-liter figure seen in the TX-series entries and reflects a heavier-duty front axle assembly.
  • For the TXG23, TXG237, and TXG237F3, a first-change-only interval of 50 hours is specified alongside the standard 300-hour normal-use change interval. An early drain at 50 hours is a common practice intended to remove metal particles and manufacturing residues that accumulate during initial component break-in.
  • The TXG-series entries also include a fluid level check at 50 hours under normal use conditions, separate from the first-change-only drain. A check interval shorter than the change interval allows for monitoring without a full fluid replacement at that point.
  • The TX 2140F and TX 2160F share the same 0.7-liter capacity and 300-hour change interval as the earlier TX 1000, TX 1300, and TX 1500, despite entering production in 1981 rather than 1978.
  • The TXG237F3 is associated with the Iseki E3112-B59 engine designation, while the TXG23 and TXG237 carry no engine qualifier in the specifications, indicating the front differential capacity and service intervals for all three TXG variants remain identical at 4 liters, 50-hour first change, and 300-hour normal change.
