Additional Notes

  • The Volvo L45G and L50G in high-speed configuration hold 2.2 liters of transfer case fluid, while the same models in low-speed configuration hold 1.2 liters. The difference reflects the greater mechanical complexity and additional gearing within the high-speed transferbox assembly.
  • The low-speed transferbox on the L45G Stage IIIb/Tier 4i appears under both a normal and a preferred use condition, each specifying the same 1.2-liter capacity and the same 1000-hour/12-month change interval. The two entries represent different fluid type approvals rather than different service schedules.
  • Across all L45G and L50G Stage IIIb/Tier 4i configurations, the transfer case change interval is set at 1000 hours or 12 months, whichever comes first. The dual-trigger format is standard practice for heavy equipment, ensuring fluid degradation from time-based oxidation is addressed even when operating hours accumulate slowly.
  • The ZL302C, covering model years 1998-2005, carries a 1-liter transfer case capacity. At 1000 hours or 12 months, the change interval matches the later G-series models despite the older platform and smaller fluid volume.
  • The high-speed and low-speed designations on the L45G and L50G refer to the output speed range of the transferbox, which affects torque distribution and drivetrain loading. The nearly doubled fluid capacity in the high-speed variant corresponds to the larger internal volume required to lubricate higher-speed rotating components.
  • The L50G mirrors the L45G exactly in transfer case fluid capacity across both speed configurations, with 2.2 liters for high-speed and 1.2 liters for low-speed. Both models share the same Stage IIIb/Tier 4i emissions classification and the same 2012-2015 production window for these specifications.
