Additional Notes

  • The BR350JG-1 with Komatsu SA6D102E-1 engine (serial number 1501 and above) carries a cooling system capacity of 23.3 liters, placing it notably below the larger crusher models in the BR lineup.
  • The BR500JG-1A with Komatsu SA6D125E-2 engine has a cooling system capacity of 43 liters, nearly double that of the BR350JG-1, reflecting the greater thermal load associated with the larger SA6D125E-series engine.
  • The BR550JG-1 with Komatsu SAA6D125E-2 engine carries a cooling system capacity of 43.9 liters, a marginal increase of 0.9 liters over the BR500JG-1A despite both machines sharing the same engine family designation.
  • All three configurations list coolant capacity under normal use conditions, meaning the 23.3-liter, 43-liter, and 43.9-liter figures each apply to standard operating environments rather than severe-duty cycles.
  • The SA6D125E-2 and SAA6D125E-2 engines, fitted to the BR500JG-1A and BR550JG-1 respectively, share a closely matched cooling system volume, suggesting a common engine block architecture with minor configuration differences between the two crusher models.
