Aro 24

Transfer case fluid capacity & service interval

Aro 24 uses transfer case fluid with a capacity of 1,25 liters. Service intervals occur every 30000 km or 36 months. The data covers 5 configurations.

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

Additional Notes

  • The Aro 24 transfer case holds 1.25 liters of fluid across all listed engine variants, a relatively modest capacity consistent with a compact, light off-road vehicle transfer box rather than a heavier truck-class unit.
  • The 30,000 km change interval applies under normal use conditions, meaning the fluid is expected to remain within acceptable service limits through that distance without the accelerated degradation associated with severe-duty operation.
  • The 36-month time limit runs alongside the 30,000 km distance threshold, so whichever milestone arrives first would govern the service point under normal use conditions.
  • The 2.5-liter petrol variant covers the 1984-2006 model range, while the 2.5 D diesel spans the wider 1980-2006 range, making the diesel the earliest-introduced engine among the listed configurations.
  • The 2.5 TD turbodiesel enters the specification from 1993 onward, representing a later addition to the lineup compared to the naturally aspirated 2.5 D, yet sharing the identical 1.25-liter transfer case capacity and 30,000 km / 36-month service interval.
  • The 2.7 D and 3.1 D diesel variants, despite their larger displacement relative to the 2.5-liter engines, carry the same 1.25-liter transfer case fill capacity, indicating the transfer box unit itself is common across the range regardless of engine size.
  • The 3.1 D begins its listed range in 1989, making it the latest-introduced diesel engine among the five configurations, yet the transfer case specifications remain unchanged from those of the earlier variants.
