Rasant Kombi Trak

Differential fluid capacity & service interval

Rasant Kombi Trak uses differential fluid with a capacity range of 1,4 to 5,5 liters. Service intervals include checks at 8 and 100 hours, and changes at 500 hours or 24 months. The data covers 10 configurations.

Additional Notes

  • Across the Kombi Trak lineup, front differential fluid capacity falls into three distinct values: 1.4 liters, 2 liters, and 5.5 liters. The 1.4-liter figure is the most common, appearing across the 1203 S, 1503 S, 1703 D, 1903-series variants, RS1305, and RS1904P configurations.
  • The Rasant Kombi Trak 9045 H, introduced from 1991, carries a front differential fluid capacity of 5.5 liters — nearly four times the 1.4-liter figure shared by the smaller-displacement models. A capacity this much larger typically reflects a heavier-duty axle assembly designed for higher torque loads.
  • The RS2205T and RS2805T both specify a 2-liter front differential capacity, placing them between the 1.4-liter and 5.5-liter figures found elsewhere in the range. Both models carry a starting year of 2000.
  • The 1203 S, 1503 S, 1703 D, and 1903-series Kombi Trak models, all introduced from 1988 or 1989, share identical front differential service intervals: a fluid level check every 8 hours and a full fluid change every 500 hours under normal use conditions.
  • An 8-hour check interval, as specified for the 1988-onward Kombi Trak models, is a very short cycle by general service standards. Intervals measured in operating hours rather than calendar time or distance are characteristic of agricultural or construction equipment, where machines may accumulate hours rapidly under variable load conditions.
  • The RS-series models introduced from 2000 — RS1305, RS1904P, RS2205T, and RS2805T — specify a check interval of 100 hours, compared to the 8-hour check interval on the earlier Kombi Trak models. Both generations share the same 500-hour change interval under normal use.
  • The RS-series front differential change interval adds a time-based threshold of 24 months alongside the 500-hour operating limit. The earlier Kombi Trak models specify only the 500-hour interval, with no calendar-based alternative stated in the specifications.
  • The 1903 S, SD, and 15 variants, starting from 1989, and the 1903 D, starting from 1988, are listed as separate configurations despite sharing the same 1.4-liter front differential capacity and identical 8-hour check and 500-hour change intervals under normal use conditions.
