Iveco Massif, 33S15

Transfer case fluid capacity & service interval

Iveco Massif and 33S15 models require 2,4 liters of transfer case fluid. Service intervals occur every 40000 km, 24 months, or 800 hours. The data covers 2 configurations.

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

TypeSpecifications
Massif 3.0 HPI (107 kW) (2008-2011)
  • Use: Normal
  • Capacity 2,4 liter
  • Change 40000 km/ 24 months/ 800 hours
Massif 3.0 HPT (129 kW) (2008-2011)
  • Use: Normal
  • Capacity 2,4 liter
  • Change 40000 km/ 24 months/ 800 hours

Additional Notes

  • Both the Iveco Massif 3.0 HPI (107 kW) and the 3.0 HPT (129 kW) share an identical transfer case fluid capacity of 2.4 liters, which is consistent with a service fill rather than a full overhaul or dry-fill quantity.
  • The 2.4-liter capacity figure applies to the transfer box specifically, as noted in the specifications, distinguishing the transfer case service from any associated gearbox or axle fluid service.
  • Under normal use conditions, the transfer case fluid change interval is defined by three separate thresholds: 40,000 km, 24 months, or 800 hours, whichever is reached first.
  • The 800-hour threshold in the interval specification reflects a time-in-operation measure, which is relevant for vehicles used in low-mileage but high-running-time applications such as off-road or agricultural work.
  • The 24-month calendar interval means that even with minimal distance or operating hours accumulated, a fluid change is due within two years under normal use conditions.
  • The specifications for the 3.0 HPI and 3.0 HPT variants across 2008-2011 show no differentiation in transfer case fluid capacity or service intervals despite the 22 kW difference in power output between the two engines.
