D375A-8 Crawler Dozer

Description

The D375A-8 crawler dozer features an EPA Tier 4 Final certified engine that produces over 20% more horsepower while the dozer is traveling in the reverse direction.  The additional horsepower yields faster cycle times and a productivity increase of up to 18%. 

 

This mining-class dozer also comes with structural enhancements for increased durability of the mainframe and track frame. The D375A-8 also features an improved suspended undercarriage, larger viscous cab mounts, and a new air-suspension heated and ventilated seat for overall operator comfort.

 

Under the Hood

  • A powerful Tier 4 Final SAA6D170E-7 engine with a net horsepower of 609 HP in the forward direction and 748 HP in the reverse direction.
  • No Selective Catalytic Reduction (SCR) system or Diesel Exhaust Fluid (DEF) required.
  • Variable Geometry Turbocharger (VGT) improves low speed response and boost.
  • High pressure, common rail fuel injection system.
  • Dual Komatsu Diesel Particulate Filters (KDPFs).
  • Large capacity and high-efficiency exhaust gas recirculation coolers.
  • Automatic, three-speed transmission with an automatically engaging lockup torque converter provides increased fuel efficiency and faster ground speeds during long pushes.

 

Machine Performance Enhancements

  • Changes to suspended undercarriage, cab isolators, operator seat, and ergonomics of operator interface significantly improve operator comfort and yield more productive shifts.
  • Structural enhancements of track frame and mainframe increase major component life.
  • New single link blade support and larger trunnion bearings reduce maintenance, increase blade stiffness, and minimize blade shake.
  • Standard features such as blade auto-pitch, ripper auto-return, and shoe slip control reduce operator fatigue and increase productivity.
  • Improved visibility to cutting edge and ripper point.
