Iveco-Astra ADT

Differential fluid capacity & service interval

Iveco-Astra ADT differential fluid capacity ranges from 14 to 35 liters. Service intervals include 100 hours, 1000 hours, or 12 months. The data covers 7 configurations.

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

Additional Notes

  • The Iveco-Astra ADT front differential capacity splits into two distinct values across configurations: 14 liters for the 25C, 30C, 35C, 40C, and 40D variants, and 35 liters for the 30D variant. The 35-liter figure is notably higher and reflects a larger differential assembly requiring a substantially greater fluid volume to fill.
  • The 14-liter front differential capacity appears across both Cursor 10 (F3A) and Cursor 13 (F3B) engine families, covering the 25C, 30C, 35C, 40C, and 40D model designations under normal use conditions.
  • The 30D with the Iveco Cursor 10 (F3A) engine, introduced from 2014, carries a front differential capacity of 35 liters under normal use, paired with a change interval of 1,000 hours or 12 months, whichever comes first. The dual-trigger interval means the fluid is replaced at the earlier of the two thresholds.
  • An initial service interval of 100 hours applies to the 30D front differential, separate from the standard 1,000-hour or 12-month normal use schedule. Initial service intervals are common in heavy equipment to remove metal particles and contaminants generated during the break-in period of new or rebuilt components.
  • The 30C and 30D share the same model number prefix but differ in front differential capacity: the 30C specifies 14 liters with no listed change interval, while the 30D specifies 35 liters with both a normal and an initial service interval. The 30C covers model years 2007-2014, and the 30D begins from 2014.
  • Among the Cursor 13 (F3B)-powered variants, the 35C, 40C, and 40D all share the 14-liter front differential capacity under normal use conditions, with no differentiation in capacity across those three configurations.
