Iseki TK

Differential fluid capacity & service interval

Iseki TK differential fluid capacity ranges from 4 to 7,5 liters. Service intervals include checking at 10 and 50 hours, and changing at 200 and 600 hours. The data covers 5 configurations.

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

Additional Notes

  • The Iseki TK front differential capacity splits into two distinct values across the TK lineup: 4 liters for the TK 527 F, TK 532 F, TK 538 F, and TK 538 FH, and 7.5 liters for the TK 546.
  • A 4-liter front differential capacity is shared identically across the TK 527 F, TK 532 F, TK 538 F, and TK 538 FH, indicating a common front axle assembly among those four variants.
  • The TK 546 front differential holds 7.5 liters, which is nearly double the 4-liter figure seen in the smaller F-series variants, reflecting a physically larger differential housing.
  • Under normal use conditions, the TK 527 F, TK 532 F, TK 538 F, and TK 538 FH all share a check interval of 10 hours for the front differential fluid.
  • The TK 546 front differential carries a check interval of 50 hours under normal use conditions, which is five times longer than the 10-hour check interval specified for the four smaller variants.
  • The front differential fluid change interval for the TK 527 F, TK 532 F, TK 538 F, and TK 538 FH is set at 200 hours under normal use conditions.
  • The TK 546 front differential fluid change interval under normal use conditions is 600 hours, three times the 200-hour interval assigned to the smaller F-series models.
  • All five variants carry a starting year of 1998 for the front differential specifications listed here.
