Additional Notes

  • The Iseki SF230FH front differential holds between 2.5 and 4.1 liters, a notably wide range that reflects variation across assembly tolerances or configuration states rather than a single fixed fill volume.
  • Across the SF300, SF310, SF330, and SF370, the rear differential capacity is uniformly 4.1 liters, while front differential capacities differ by model — the SF300 and SF330 specify 0.8 liters and the SF310 and SF370 specify 0.7 liters.
  • The first-change-only interval across all SF300, SF310, SF330, SF370, and SF230FH models is set at 50 hours. This early drain is standard practice for new or rebuilt differentials, as it removes metal particles generated during initial component wear-in.
  • Following the first change, normal-use intervals for the SF300, SF310, SF330, SF370, and SF230FH models extend to 200 hours, with a fluid level check specified at every 10 hours.
  • The SFH220T and SFH240F rear differentials, both introduced from 2008, share a 2.5-liter capacity and a longer normal-use change interval of 300 hours, compared to the 200-hour interval on the earlier SF-series models.
  • Despite the longer 300-hour change interval on the SFH220T and SFH240F, the 10-hour check frequency and the 50-hour first-change interval remain consistent with the rest of the SF range.
  • The SFH220T and SFH240F specifications cover only the rear differential, whereas models such as the SF300, SF310, SF330, and SF370 include both front and rear differential entries.
