Komatsu Charge Pumps Guide

Komatsu charge pumps maintain pressure and support specific hydraulic or transmission-related systems. They are not interchangeable with main hydraulic pumps simply because both are part of broader pump systems.


What Charge Pumps Do

  • Maintain charge pressure
  • Support hydrostatic or transmission systems
  • Feed fluid to related system components

Charge pumps are often overlooked during parts research because customers may know the machine uses a pump, but not which pump section or support pump the system actually requires.


Why Charge Pump Identification Matters

Charge pumps can vary by machine configuration, serial number, and system layout. The correct part should be confirmed against the appropriate diagram and serial-number-specific parts book references.


Where to Go Next


Always confirm using your Komatsu parts book for final fitment.
