Product Features & Engineering Advantages
  • Critical Component for Engine Longevity: The oil pump is the heart of the engine lubrication system, drawing oil from the oil pan and forcing it under pressure through oil galleries to rotating bearings, sliding pistons, and the camshaft.
  • Precision Gear Design: Features precision-engineered gears with 21-tooth configuration that ensures consistent oil flow and pressure to critical engine components.
  • High-Pressure Performance: Designed to deliver high-pressure oil to components requiring regular lubrication such as crankshaft and camshaft bearings, maintaining adequate pressure under heavy load conditions.
  • Robust Construction: Manufactured from high-strength materials with cast iron housing and hardened steel gears, built to withstand continuous operation in demanding construction and mining environments.
  • Direct Crankshaft Drive: Engineered for direct drive from the crankshaft, ensuring positive and reliable operation whenever the engine is running.
  • Compatible with Various Engine Configurations: Suitable for both naturally aspirated and turbocharged 6D125 engine variants.
  • Multiple Condition Options Available: Available as brand new aftermarket units, professionally remanufactured pumps, or inspected used pumps.
Quality Assurance
  • 100% Tested – Every oil pump undergoes functional testing to ensure proper pressure and flow characteristics
  • 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.
