  • OEM Standard – Manufactured to meet or exceed original equipment specifications
  • Warranty – 6-month warranty against manufacturing defects
  • Global Shipping – Fast DHL, FedEx, UPS shipping available from multiple warehouses
  • Expert Support – Assistance with part identification using engine codes or old part numbers
Installation Note
The oil pump is typically located at the front of the engine or inside the oil pan. When installing a new oil pump on a Komatsu 6D125 engine, it is critical to ensure proper priming before startup to avoid dry running damage. Always inspect the oil pickup tube O-ring and screen for debris during installation. Professional installation is recommended due to the precision required for proper alignment and sealing. Regular oil changes with the correct viscosity oil will extend the life of both the oil pump and the engine.
Warning: Never operate the engine without verifying proper oil pressure after pump replacement. Low oil pressure can cause immediate and severe engine damage.
