Additional Notes

  • The Wacker Neuson RD16 and RD16IRH, both from 2009 onward, share an identical cooling system capacity of 4.75 liters, with a check interval of every 10 hours of operation.
  • The RD27-100 and RD27-120 produced between 2006-2008 also carry a 4.75-liter cooling system capacity, placing them in the same fill range as the smaller RD16 models despite their larger designation.
  • From 2009 onward, the RD27-100 and RD27-120 cooling system capacity increases to 6 liters, a rise of 1.25 liters compared to the 2006-2008 versions of the same models.
  • The 10-hour check interval applies uniformly across all listed RD series models and year ranges, reflecting the demanding operating conditions typical of asphalt compaction equipment.
  • A coolant change interval of 72 months or 12,000 hours is specified for the RD27-100 and RD27-120 from 2009 onward. The dual-format interval means service is due at whichever threshold is reached first, accounting for both calendar aging and operational wear of the coolant.
  • No coolant change interval is listed for the 2006-2008 RD27-100 and RD27-120, nor for the RD16 and RD16IRH, meaning only the periodic check at 10 hours is specified for those configurations.
