Additional Notes

  • The SD122D, SD122Dx, and SD122F all share a transfer box fluid capacity of 1.8 liters, which represents the service fill volume for routine maintenance rather than a full overhaul quantity.
  • Across the Volvo SD122D, SD122Dx, and SD122F compactors from 2007-2012, the transfer box fluid change interval is set at 1,000 hours or 12 months under normal use conditions, whichever comes first.
  • The dual-trigger interval of 1,000 hours or 12 months means that even low-utilization machines reaching the calendar threshold are due for a transfer box fluid change before the hour meter reaches 1,000.
  • The 1.8-liter capacity is consistent across all three SD122 variants, indicating no differentiation in transfer box size between the standard, Dx, and F configurations within the 2007-2012 model range.
  • The normal use condition tied to the 1,000-hour/12-month interval applies uniformly to the SD122D, SD122Dx, and SD122F, with no separate severe-duty interval listed for the transfer box on these models.
